Essay --

Why Mt. Lassen is what it is today Lassen Peak, also known as Mount Lassen, is the southernmost active volcano in the Cascade Range. It is part of the Cascade Volcanic Arc which is an arc that covers southwestern British Columbia to northern California. Located in the Shasta Cascade region of Northern California, Lassen rises 2,000 meters above the surrounding terrain and has a volume of 0.5 cubic miles, making it one of the largest lava domes on Earth. It was created on the destroyed northeastern side of now gone Mount Tehama, a stratovolcano that was at least 1,000 feet higher than Lassen Peak. Lassen Peak was named in honor of the Danish blacksmith Peter Lassen, who guided immigrants past this peak to the Sacramento Valley during the 1830s. His trail never found global long-term use because it was considered unsafe. This trail was replaced by the Nobles Emigrant Trail, named for the guide, William Nobles. In 1864, Helen Tanner Brodt became the first woman to reach the summit of Lassen Peak. A tarn lake on Lassen Peak was named "Lake Helen" in her honor. In the 1914 to 1921 time zone, Lassen Peak emerged from inactivity with a series of steam explosions, dacite lava flows, and volcanic mud flows. There were 200 to 400 volcanic eruptions during this period of activity. Because of the eruptive activity and the area's brilliant volcanic beauty, Lassen Peak, Cinder Cone and the area surrounding were designated as the Lassen Volcanic National Park on August 9, 1916. Mt. Lassen eruptions On May 22, 1915, an explosive eruption at Lassen Peak devastated nearby areas and rained volcanic ash farther 200 miles to the east! This explosion was the most powerful in a series of eruptions from 1914 through 1917. ... ...e than 30 volcanoes that have erupted over the past 300,000 years in the Lassen Peak volcanic area. 6. Lassen Peak has the highest known winter snowfall amounts in California. There is an average annual snowfall of 660 in, and in some years, more than 1,000 inches of snowfall at its base altitude of 8,250 feet at Lake Helen. 7. The Mount Lassen area receives more precipitation than anywhere in the Cascade Range south of the Three Sisters volcanoes in Oregon. 8. The heavy annual snowfall on Lassen Peak creates fourteen permanent patches of snow on and around the mountain top, despite Lassen's rather modest elevation, but no glaciers. 9. Lightning has been known to strike the summit of the volcano frequently during summer thunderstorms. 10. Lassen Peak and Mount St. Helens are the only two volcanoes in the contiguous United States to erupt during the 20th century.

The Texture of the Sixth Poem of Song of Myself :: Song of Myself Essays

The Texture of the Sixth Poem of Song of Myself In number six of Whitman's poetic series "Song of Myself," it seems that he is trying to convey the point that to die is not what people make it out to be. Whitman throughout many of the poems in this series, describes death as "lucky" and beneficial. He also explains how death leads to the beginning of life in this poem. The tone at the very beginning of this poem seems a bit youthful. Especially when the question "What is grass?" is posed to him by a child. This opening line gives you a great mental picture of a child about the age of five or six, walking up and asking innocently a question that you cannot answer. By using the line, "fetching it to me with full/ hands;" Whitman gives you that image right from the beginning. From there he goes into this sort of naïve tone, guessing what grass means. By doing so he shows himself to be mortal and not all-knowing. During this time in the poem, he gives beautiful metaphorical imagery, comparing the grass to other things and illustrating a better idea of what the grass is. Also during this speculation period, the wording becomes denser, as the ideas become complex. Whitman moves from the single-lined "childish" voice, into the adult stage of the poem. Here, he becomes surer of what the grass is and does less guessing. Around line 101, Whitman starts toward the turning point in the essay, describing the death aspect of the grass. Words like "dark" change the mood of the poem to a slower, sadder state. At line 110, the poem takes a sudden change and reads much quicker. It changes into a kind of argument and Whitman speaks more affirmatively. Now it seems as if he has been enlightened and understands what the grass is. The feeling of death changes to life and darkness changes to light. In a subtle way, he gives the reader a feeling of lightness and life, because in the last four lines he begins all of the lines with "A's" and as you read it you get that choral "Hallelujah" feeling. Whitman shows you the light. He tells you why death is a good thing. There is no more fear. "To die is different from what any one supposed, and/luckier.

Psy: Obedience Essay

Obedience is the act of practicing obeying; dutiful or submissive compliance. Humans have an instinct to obey because of the role authority plays. Milgram’s research proves my point in his case study that involved shocks of voltage. From birth, we learn that everything has a consequence or punishment after an action. Children learn simple philosophies in their youngest age such as obeying their parent’s requests. Something as simple as eating vegetables has a consequence. A reward gives the child satisfaction to emphasize the good behavior or, in the opposite case, bad behavior. As humans get older, this simple idea enlarges when it applies to different phases in life. Scientists like Milgrim and Marta Laupa study factors that play a role in obedience using variables like electrical shocks. In the psychology department, scientists like Milgrim, studied obedience to understand human behavior. He used cruel and unusual ways to study how humans will react to authority. The punishments included electrical shocks at different voltages. This is just one of way psychologists test authority versus obedience. His experiment involved 42 participants, some of them being the enforcer and some acting as the victim. The authority role would execute the victim with electrical shocks beginning from 15 to 450. Milgrim’s blind case study took place at Harvard University where the participants agreed to take part without any kind of explanation. The authoritative volunteer requested the number of voltages from the patient. No one objected the voltage until it reached a maximum of 450. As the voltage amount rose, the participants allegedly showed signs of stress and nervousness but never refused the electricity until the last and most fatal amount of voltage. Later, Milgrim altered the study by placing the authority figure outside of the electricity room. He or she used a loudspeaker to inform the victim of the situation. Participants were all of the sudden more reluctant to obey. This unethical experiment showed researchers and fellow observers how humans obey powerful authority to almost fatal conditions. Rather than disobeying, humans will instinctively continue even when conditions are close to death. Milgrim’s results differ from Laupa. Unlike Milgrim’s results, Laupa’s were less shocking, literally. The process involved students who were appointed as conflict managers or honor patrol. The chosen ones were taught to approach students to resolve arguments such as turn-taking. Laupa required 80 children from four classes: first grade, third grade, fifth grade, and seventh grade. Subjects were then put in situations where they must chose to listen to another person. For example, the scientist listed a few such as la dy versus former peer authority. This example is fundamental to the understanding of obedience. This illustration baffles children because they are put in a situation where the lady has adult status, which shows authority but no knowledge, but the former peer authority shows knowledge but no adult status like the previous lady. Laupa’s case proves that children are a biased subject to chose for the obedience in Milgrim’s case because children have a different way of thinking compared to adults who have prior experience to the social world. Children’s naive way of thinking benefits them since they are not interested in social system that adults are in everyday. Common sense would tell us that most people believe obedience is a critical aspect in social life and plays a great role in maintaining social order. On the contrary, every human being at different ages posses different aspirations that reflect their behavior. While some people respect authority by obeying, many do not, such as criminals or the students in detention. In Milgrim’s study, it is obvious that almost everyone respected authority possibly because they were under the impression that there were greater consequences or that they were in dire need to comply. In Laupa’s study, however, it showed that children were doubtful to peer authority and even adult authority. While some children are less timid than others, children have the instinct to question others because younger people are unaware of the social status adult figures hold. When comparing the two cases studies by Milgrim and Laupa, observers would agree that from childhood, people identify authority and obey them according to their figure in society or the status they hold.

Early childhood deprivation Essay

Early childhood deprivation varies from the areas of health, nutrition and education (Biller and Solomon, 1996). However various intonations have been put forward to improve children’s welfare that aim at promoting early childhood care and foster holistic development and realization of child’s potential. Early childhood deprivations hamper child’s development and thus killing the future viable generation. In this regard, there’s need to invest in children welfare. During early childhood, child’s deprivation has the most profound negative influence on child’s development in terms of physical, mental and social domains. In most cases of children deprivation, the children usually lack essential interventions responsible to promote healthy development, thus there is hardly any pre-existing normalcy. Although deprivation occurs in children across all human race; black or white, girls or boys, rich or poor, the worst form of deprivation occurs in children who come from economically poor background. The tangible impact of childhood deprivation is in terms of mental health damage since most incidences of deprivation are interpreted as threats to the child, thereby causing trauma. However, in extreme cases of deprivation in childhood the children are deprived off stimulation or nurture. Types of Deprivation Child deprivation during the tender age can be classified in terms of Absolute deprivation, Relative deprivation and Perceived deprivation. Absolute deprivation entails lack of or preventing the child from gaining access to absolute development needs such as food, water, protection touch of who without the children usually dies the challenge with absolute deprivation is how much quantity is enough for the infants. For instance, studies show that infants or children who are not touched usually develop â€Å"nonorganic failure to thrive† syndrome (Brooks-Gunn, J. et al. , 2004, p. 106) that make then refuse to eat and became suicidal. Additionally, touch is necessary for emotional bond for the child that is responsible for creation of brain patten to support interaction behaviors and form basic for later empathy development, therefore, abosute deprivation is critical especially to child development and sustainability. Relative deprivation described as lack of child’s developmental needs that are determined by subculture and culture in which the child resides. Unfortunately, developmental expectations in relation to children development usually changes overtime. For instance in United States of America it has been a norm culture that children at age of 6 years are ready and expected to enter the first grade in order to learn how to write, read and do basic mathematics. Unfortunately, research by Biller and Solomon (1996) indicates that 20-30% of all children are not ready by this time. Moreover culture also oblige the parents give special attention to their children in terms of facilitating celebrating children status like birthday in order to promote children social conscious development, therefore in circumstances where the culture through parents denies children typical opportunity which is considered essential for a healthy child development it becomes deprivation. Moreover, children worldwide live in varied living conditions with resources never been equitably distributed to all children depending on familial social, ethnic identity, social economic and county of origin, this inequity hampers children development physically, socially and mentally precisely most children who are deprived off relatively usually develop maternal depression, abuse and family violence. Perceived deprivation results from children’s and parents feeling that the children are deprived due to frustrated desires as opposed to unmet needs. For instance, in a family set up there is child rivalry because it is normal parents usually favor some children than others. As a result, the child that is not favored feels unwanted no matter how hard parents can convince them. For instance, studies show that children who are taken good care of after incidences of neglect, despite sufficient supply of food and emotional support, they tend to exhibit signs of mistrust due to perceived deprivation (Biller and Solomon, 1996). The causes of deprivation The causes of deprivation vary across populations and societies. However, the most causes are familiar such as low skills and education, membership in minority groups, undevelopment and unemployment, social isolate from society’s mainstream and persistent and interrogational transmission of poverty to tolerate this factor (Brooks-Gunn, J. et al. , 2004), studies reveal that children in neigh hood without deprivation signs exhibited good growth and development outcomes as opposed to those with signs of deprivation. However, there are a number of additional aspects that greatly contribute to childhood deprivation, child neglect in the welfare system is a common form of child neglect in us where parents are givers fail to give the child essential resources as food, medical care, shelter and clothing which endanger child wellbeing. Development impacts of Deprivation Response of children to deprivation varies from one individual to another in the sense that human beings are shaped by the interaction of their genetic predisposition with stimulation, nurture, threats and other ennental forces. It should be noted that infancy experiences of children have a profound and long term effect on mental, physical, social and emotional characteristics, therefore, when deprivation is chronically and insidious pervasive the results are diastoles irreparable intellectual deficits, chromic health problem, mental illness, physical disabilities (Biller and Solomon, 1996), emotional disturbances and behavioral problem. Conclusion The paper has discussed early childhood deprivation and its major dimensions and its related effects. Fortunately, the effects of early childhood deprivation are treatable (Brooks-Gunn, J. et al. , 2004) by placing deprived child on a long-term and well structured relationship where the child learn or relearn that positive social interaction to offset the negative impact. It is encouraging also that across US there are various programs and interventions that are aimed at ensuring those children and/or individual degraded by deprivation are returned to normalcy.

Deception Point Page 80

â€Å"Do you have dogs, Dr. Harper?† He glanced up. â€Å"I'm sorry?† â€Å"I just thought it was odd. You told me that shortly after this Canadian geologist radioed in the meteorite coordinates, his sled dogs ran blindly into a crevasse?† â€Å"There was a storm. They were off course.† Gabrielle shrugged, letting her skepticism show. â€Å"Yeah†¦ okay.† Harper clearly sensed her hesitation. â€Å"What are you saying?† â€Å"I don't know. There's just a lot of coincidence surrounding this discovery. A Canadian geologist transmits meteorite coordinates on a frequency that only NASA can hear? And then his sled dogs run blindly off a cliff?† She paused. â€Å"You obviously understand that this geologist's death paved the way for this entire NASA triumph.† The color drained from Harper's face. â€Å"You think the administrator would kill over this meteorite.† Big politics. Big money, Gabrielle thought. â€Å"Let me talk to the senator and we'll be in touch. Is there a back way out of here?† Gabrielle Ashe left a pale Chris Harper and descended a fire stairwell into a deserted alley behind NASA. She flagged down a taxi that had just dropped off more NASA celebrators. â€Å"Westbrooke Place Luxury Apartments,† she told the driver. She was about to make Senator Sexton a much happier man. 94 Wondering what she had agreed to, Rachel stood near the entrance of the G4 cockpit, stretching a radio transceiver cable into the cabin so she could place her call out of earshot of the pilot. Corky and Tolland looked on. Although Rachel and NRO director William Pickering had planned to maintain radio silence until her arrival at Bollings Air Force Base outside of D.C., Rachel now had information she was certain Pickering would want to hear immediately. She had phoned his secure cellular, which he carried at all times. When William Pickering came on the line, he was all business. â€Å"Speak with care, please. I cannot guarantee this connection.† Rachel understood. Pickering's cellular, like most NRO field phones, had an indicator that detected unsecured incoming calls. Because Rachel was on a radiophone, one of the least secure communication modes available, Pickering's phone had warned him. This conversation would need to be vague. No names. No locations. â€Å"My voice is my identity,† Rachel said, using the standard field greeting in this situation. She had expected the director's response would be displeasure that she had risked contacting him, but Pickering's reaction sounded positive. â€Å"Yes, I was about to make contact with you myself. We need to redirect. I'm concerned you may have a welcoming party.† Rachel felt a sudden trepidation. Someone is watching us. She could hear the danger in Pickering's tone. Redirect. He would be pleased to know she had called to make that exact request, albeit for entirely different reasons. â€Å"The issue of authenticity,† Rachel said. â€Å"We've been discussing it. We may have a way to confirm or deny categorically.† â€Å"Excellent. There have been developments, and at least then I would have solid ground on which to proceed.† â€Å"The proof involves our making a quick stop. One of us has access to a laboratory facility-â€Å" â€Å"No exact locations, please. For your own safety.† Rachel had no intention of broadcasting her plans over this line. â€Å"Can you get us clearance to land at GAS-AC?† Pickering was silent a moment. Rachel sensed he was trying to process the word. GAS-AC was an obscure NRO gisting shorthand for the Coast Guard's Group Air Station Atlantic City. Rachel hoped the director would know it. â€Å"Yes,† he finally said. â€Å"I can arrange that. Is that your final destination?† â€Å"No. We will require further helicopter transport.† â€Å"An aircraft will be waiting.† â€Å"Thank you.† â€Å"I recommend you exercise extreme caution until we know more. Speak to no one. Your suspicions have drawn deep concern among powerful parties.† Tench, Rachel thought, wishing she had managed to make contact with the President directly. â€Å"I am currently in my car, en route to meet the woman in question. She has requested a private meeting in a neutral location. It should reveal much.† Pickering is driving somewhere to meet Tench? Whatever Tench was going to tell him must be important if she refused to tell him on the phone. Pickering said, â€Å"Do not discuss your final coordinates with anyone. And no more radio contact. Is that clear?† â€Å"Yes, sir. We'll be at GAS-AC in an hour.† â€Å"Transport will be arranged. When you reach your ultimate destination, you can call me via more secure channels.† He paused. â€Å"I cannot overstate the importance of secrecy to your safety. You have made powerful enemies tonight. Take appropriate caution.† Pickering was gone. Rachel felt tense as she closed the connection and turned to Tolland and Corky. â€Å"Change of destination?† Tolland said, looking eager for answers. Rachel nodded, feeling reluctant. â€Å"The Goya.† Corky sighed, glancing down at the meteorite sample in his hand. â€Å"I still can't imagine NASA could possibly have†¦ † He faded off, looking more worried with every passing minute. We'll know soon enough, Rachel thought. She went into the cockpit and returned the radio transceiver. Glancing out the windscreen at the rolling plateau of moonlit clouds racing beneath them, she had the unsettling feeling they were not going to like what they found onboard Tolland's ship. 95 William Pickering felt an unusual solitude as he drove his sedan down the Leesburg Highway. It was almost 2:00 A.M., and the road was empty. It had been years since he'd been driving this late. Marjorie Tench's raspy voice still grated on his mind. Meet me at the FDR Memorial. Pickering tried to recall the last time he had seen Marjorie Tench face-to-face-never a pleasant experience. It had been two months ago. At the White House. Tench was seated opposite Pickering at a long oak table surrounded by members of the National Security Council, Joint Chiefs, CIA, President Herney, and the administrator of NASA. â€Å"Gentlemen,† the head of the CIA had said, looking directly at Marjorie Tench. â€Å"Yet again, I am before you to urge this administration to confront the ongoing security crisis of NASA.† The declaration took no one in the room by surprise. NASA's security woes had become a tired issue in the intelligence community. Two days previously, more than three hundred high-resolution satellite photos from one of NASA's earth-observing satellites had been stolen by hackers out of a NASA database. The photos-inadvertently revealing a classified U.S. military training facility in North Africa-had turned up on the black market, where they had been purchased by hostile intelligence agencies in the Middle East. â€Å"Despite the best of intentions,† the CIA director said with a weary voice, â€Å"NASA continues to be a threat to national security. Simply put, our space agency is not equipped to protect the data and technologies they develop.† â€Å"I realize,† the President replied, â€Å"that there have been indiscretions. Damaging leaks. And it troubles me deeply.† He motioned across the table to the stern face of NASA administrator Lawrence Ekstrom. â€Å"We are yet again looking into ways to tighten NASA's security.† â€Å"With due respect,† the CIA director said, â€Å"whatever security changes NASA implements will be ineffective as long as NASA operations remain outside the umbrella of the United States intelligence community.† The statement brought an uneasy rustle from those assembled. Everyone knew where this was headed.

Functions of Management Essay

United Health group is a major insurance company that provides medical and mental health coverage to its consumers. The organization manages Medicaid and Medicare accounts as well as commercial accounts from employers. Providing healthcare insurance is a competitive job, therefore, the management of the organization has to use the four functions of management to remain in the competition. The four function of management are planning, organizing, leading and controlling. In this paper, we will discuss the four functions of management and how it relates to the organization. The four functions of management is planning, organizing, leading and, controlling. Planning is for the goals of the organization, planning sets the stage for action and major achievements. Organizing is assembling and coordinating human, financial resources needed to achieve the goals. This could be organizing activities such as grouping jobs into work units, marshaling and allocating resources and creating conditions so that people and things work together to achieve maximum success. Leading is stimulating people to be high performers. Leading can take place in departments, teams as well as divisions. By encouraging high performers, you are increasing their inner moral, making them feel and believe they can complete their goals rather it is individual goals that coincide with the organization’s goals. Another management function is controlling, managers make sure the organization’s resources are being used as planned and that the organization is meeting its goals for quality and safety. The four functions of management have in common is to achieve the goals for the organization. The four functions all work together. There are three different levels in management; top level managers, middle level managers and, front line managers. Top level managers are typically the CEO, COO or CIO. Middle level managers are under the top level managers and, frontline managers are considered operational managers. The top level manager determines and identifies the goals that are needed for the entire organization. Once the CEO has identified the goals and what steps that are  needed to achieve the goal, the information is conveyed to middle management. Middle management takes those goals and determines what’s needed to achieve the goals such as organizing workloads, teams or units. Then convey to frontline managers. Front line management does most of the leading, their more hands on with employees or teams. Front line managers assist with establishing individual goals that will benefit the company and coincide with the company’s goals. Front line managers also use controlling by making sure the e mployees utilize company resources if needed. Also by making sure the company goals are being met. The organization uses all four of the management functions. There have been many cases of increased health issues within call center environments such as; obesity, high blood pressure, depression and anxiety issues. The organization created incentives to make the idea more appealing to the employees. The organization has decided to inspire and motivate their employees to take better care of their health. By creating the goals of decreasing the health issues within the office setting the organization set their stage for action so they could achieve these goals. Now that the goal has been established the organization needs to assemble humans, physical information to coordinate ways to achieve the goals. The organization started providing bonus incentives such has decrease in insurance if you’re passed a bio metric screening. The organization also begin to partner with Weight Watchers providing employee discounts, LA Fitness (discounted membership), provide stress management classes along, with providing ways to exercise in the office. There are different teams within the company with a goal of losing the most weight. The teams encourage one another and provide support during their weight loss journey. All teams support and encourage with the expectations of dropping the weight and defeating the other team. The teams have weekly check-ins where the members have to weigh in, report their meal plans. By utilizing the four functions of management, the organization has been able to lower their premiums for their employees, and increase better health within the organization. The organization identified the issue of health  concerns within the office setting, set the goals of prevention and reduction. With those plans of prevention and reduction the organization was able to organize employees and coordinate ways to achieve the goals. The staff coordinated and provided information to their employees to educate and prevent. The leaders promoted the resources and encouraged those to be active and participate in all the resources the organization has to offer.

General Advice †¢ Answering questions. The questions are meant to let you show the biology you know. There are no trick questions. When you are writing your answers remember that another person has to be able to read it. o o o o o o o o Do not waste time by writing out the question before you start to answer. Keep your handwriting clear and legible. Keep you answer in the lines on the question paper.If you write in the margin, at the bottom of a page, or on blank pages, part of your answer might be missed. If you have to cross out something, put a line through, but do not scribble all over it. If you have to use a different space to write another answer to one you have crossed out, then put a note to say where it is, e. g. answer on page 5 Written papers are now marked on computer screen so your written paper will be scanned. If you write on the margin the scanner may not be able to copy this. Try to be precise, in other word be accurate in what you say. Read also Lab 2 BiologyUsing biological terms correctly can help. Do not use word like â€Å"it†, â€Å"they†, â€Å"effect†, â€Å"affect† without any more explanation. A sentence like â€Å"It has an effect on the body† or â€Å"They affect the process† does not say anything. – If you use the word â€Å"it† or â€Å"they â€Å"– think WHAT? – If you use the word â€Å"affect† or â€Å"effect† – think HOW? – e. g. State why magnesium ions are important for healthy plant development. [1] – â€Å"it are needed by the plant† is true but too vague. – â€Å"They are needed by the leaves† is still too vague – Ask yourself: What is it or they? What is the â€Å"need†? â€Å"Magnesium is needed to make chlorophyll† is a better answer – â€Å"Magnesium is part of a chlorophyll molecule. † Good answer! †¢ Terms. These are the n ames used in biology. These will be used in questions. You will get more marks if you can use them correctly in you examination. Ask your teacher if you are unsure of the different meanings between biological terms. o o Try to use the correct spelling. The person marking your answer will try to recognise what word you mean, but if the spelling is too wrong, then they cannot allow you a mark. Some biological terms have very similar spelling.One example is â€Å"ureter†, urethra† and â€Å"uterus†. If your mis-spelling is â€Å"uretus†, it could be â€Å"ureters† or â€Å"uterus†. Other common examples are ovum, ova, ovary and ovule, testes and testa; sucrose and sucrase. Do not try to mix the spellings of two words when you are not sure which of them is the correct answer, e. g. meitosis, when you are not sure whether the answer is mitosis or meiosis, or urether, when you are not sure if the answer is ureter or urethra. You need to check caref ully that you have used the right word when similar terms are used in the same topic , e. g. urea and urine, ureter and urethra. semen and sperm o o †¢ Writing in you own words. You sometimes have to write two or more sentences to answer a question. o o Use short sentences. If you write long sentences you can get mixed up. It is hard to find correct statements in a muddled answer. You are often asked to write down something you have learned. Make sure you have learnt the meanings of the common terms used in biology, e. g. photosynthesis, osmosis, fermentation. In the revision checklist there is a list of the terms which you should be able to â€Å"define†. You also need be able to write down the meaning of more complicated ideas, e. g. evel of organisation, natural selection, global warming, eutrophication. o What you should look for in a question 1) †¢ †¢ †¢ †¢ †¢ The number of marks. In multiple choice questions there is only one mark for a cor rect answer. Other sorts of question show how many marks at the end of each part like this [2]. The number of marks helps you decide how much to write. The number of marks is a guide to how long to spend on each question or parts of a question. If you allow about 1 minute per mark then you should finish in time to check your answers. Do not waste time and write long answer for a question which has [1].You will only get one mark even if the rest of the answer has correct statements. If there are two or more marks do not write the same thing in two different ways, e. g. The leaf is very large. The leaf has a large surface area. The instructions. These are called command words and tell you what to do. If a question says â€Å"Show your working† when you have to do a calculation, then write down the stages of your calculation to show how you got your answer. Even if you get the final answer wrong, you may be given a mark for knowing what to do. If a question asks you to â€Å"Na me† or â€Å"State† two things only the first two will be marked.Use the numbered lines for your answers if they on the question paper. If you write more than two and the first is correct but the second one is wrong, you will only get the mark for the first one. Even if the third answer is correct, it will not be marked. Some questions have two commands in the question, for example â€Å"Predict† AND â€Å"Explain† †¦. † This means you have to say what you think will happen AND then say why you think it will happen. The Revision Checklist has a list of terms used in biology papers to tell you what to do in an answer (section 4. 3 Command words and phrases).General Biology Ii Study Guide (Online Class)Make sure you know what these terms mean. e. g. â€Å"Name the process by which green plants make sugars†, all you need to write for your answer is â€Å"Photosynthesis†. A question which asks you to â€Å"Define photosynthesis† , would expect you to write one sentence such as â€Å"The process by which green plants use light energy to make sugars†. What the question is about. Make sure you know which part of your biology is being tested Read the whole of a question carefully before you begin to answer it. Some of the parts have similar answers so you need to work out the difference between them.If you write exactly the same thing in different parts of the same question, then only one of them might be a correct answer. It helps to highlight the main features of a question. e. g. â€Å"Name the tissue that transports the sugars made by photosynthesis to other parts of the plant†. This tells you that you want a one word answer, about plant transport of sugars. Do not be put off the question is about something you have not studied.

You may have to use information from them to answer the questions. Answer each question as far as you can. Do not spend a long time staring at a question If you have forgotten something, go on to the next question or part of a question. Come back to the ones you found difficult when you have finished all of the paper. Try not to leave blanks. When you come back to a question you often remember an answer you left out. Do not waste time by writing about things unrelated to the question. Paper 1 Tips †¢ Each question tests just one thing.You have about 1 minute to read and answer each question. o Some questions test what you know and understand. For example â€Å"What part of the eye detects light? † o Some questions test if you can use what you have learned to understand new data. These questions will often have a diagram, graph or table to use. Try to decide what the question is testing as you are reading it. o To answer a question that asks â€Å"What is a characteristic feature of all living things? o You need to know the characteristic features of living things. If you know a quick way of remembering all seven then you can jot it down on the question paper. . g. MRS GREN for Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion and Nutrition, or the first letters of Real Elephants Grow Massive Red Feet Slowly, o To answer a question that has a diagram of the circulatory system and asks â€Å"In which vessel will absorbed alcohol first be found? â€Å". You need to think about what the question is asking you. – Is it about digestion? – Is it about excretion (of alcohol)? – Is it about the circulation? The question is asking about something absorbed from the gut to be transported, so it is about circulation. – Which vessel carries substances absorbed by the gut? Answer â€Å"The Hepatic Portal Vein†. So you have to choose the letter which labels the hepatic portal vein. Do not try to find a pattern in the letter order of correct answers. o The same letter could be the correct for several answers in a row. o Letter A might be the correct answers for more questions than are B, C or D. Or there could be fewer correct answers shown by letter D than any of the others. o Do not let what you have chosen for the previous questions influence what letter you choose. †¢ †¢ Written Paper Tips †¢ You should read all of a question before you begin to answer it.Different questions will ask you to do different tasks to test how well you know and understand biology. o The topic is usually the same for all different parts of the question. Remember that underlining important words will help you to be clear about what you are being asked to do. o Look for clues in the words of the question. If you see â€Å"mammal† you know that the anima ls are warm blooded and have biological systems like ours. o If you are only given a Latin name or a name you do not recognise, e. g. â€Å"dik-dik†, look to see if you are told anything about it. If you are told it is a herbivore, then you know it eats plants.The main sort of tasks you might be asked to do are: †¢ Identify features of cells, tissues organs. For example, â€Å"label on Fig. 5. 1 using labelling lines, a petal, a sepal and a stamen. To answer this question o You have to know the structure of a flower. o You also have to be able to find the structures on a diagram of a flower you may never have studied. o You then have to draw a label line to the structure and write the name next to the labelling line. If you do not draw a label line, or use and arrow, you may not get any marks even if you have found the correct structures.Use information given in the question. For example if a question asks you to â€Å"Use examples from† or â€Å"Use only this i nformation† or â€Å"With reference to Fig. 6. 2† . . . STOP and THINK! Find out what you are expected to use as examples or get information from. You will not get any marks if you use examples from somewhere else. The information can be given to you in different ways: o Diagram like a food web, a set of apparatus or biological structure. o A graph, which could be a line graph, a bar chart or a histogram. Check the headings and units carefully o A table.Check the headings and units carefully o You may have to give examples to show that you understand an idea in Biology. – After a diagram of a food web you might be asked to â€Å"Name an organism from this food web that is a primary consumer, a tertiary consumers and a producer†. – To answer this question you have to know definitions of producers, primary consumers, tertiary consumers. Then you have to show that you understand how these terms apply to the food web shown in the diagram. If you put exa mples from other food webs you have learned, you will not get any marks.After a diagram of leaf structure you may be asked to â€Å"Describe and explain the advantage of the distribution of chloroplasts shown in Fig. 8. 1† – To answer this question you have to observe the diagram and describe which cells have the most chloroplasts. Then you have to work out why this arrangement might help photosynthesis. If you write answer about what chloroplasts do you will not get any marks. Draw or interpret graphs. If you are asked to draw a graph: †¢ †¢ †¢ †¢ †¢ Choose a scale which uses most of the grid. Choose a simple scale, e. g. one small square is equal to 1 or 2 or 10 units in the data.Do not give make it hard for by having to multiply each item in the data by 2/3! o Write the name of the axes and their units, e. g. rate of water loss/ g per h , temperature/ o C, time/ s o Plot the points exactly using a sharp pencil. Draw the points lightly so tha t you can rub them out if you need to. Make them more definite when you are sure they are right. o Use a cross (x) or a dot in a circle ( ) for your plot points. o Join the points with a â€Å"line of best fit or a zig -zag line. o Remember that all curves do not have to pass through the point where the two axes meet. Do not extend you graph beyond the plotted points. If you are asked to read figures from a graph: o Make sure you work out the scale. o Make sure you read from the correct axis and put in the units. o If you are asked for a trend or pattern, describe the overall change, e. g. the line increases and then levels. off. Do not describe each point of the graph. Draw or interpret tables If you are asked to draw a table o Use a ruler and a pencil to draw the table. o Write headings for each column or row of the table. 3 o Write in units if they are needed, e. g. volume of water/cm , mass of seed/g. Do not put units in the table spaces where you write numbers. Do calculations . If you are asked to do a calculation: o You may have to find the figures from a table or graph. o Make sure that you show the units in the calculation. o Show you working. o If you use a calculator, round up the figures to the same as in the question – do not copy all the figures after the decimal point, e. g. If the question figures are 5. 6, 4. 6, then your answer should only have one number after the decimal point. Show or complete equations. You do not have to know chemical symbols for equations of the processes in biology.But it will help you to understand them if you do. o If you are asked to give either a word or a symbol equation, do not combine symbols and words in the same answer – If you have to give the word equation for anaerobic respiration by yeast, write: o o Glucose > carbon dioxide +ethanol + energy If you have to give the chemical equation for anaerobic respiration by yeast, write C6H12O6 > 2C2 H5 OH + 2CO2+ energy Do not write something like gluco se > CO2 + ethanol and energy †¢ Make comparisons. If you are asked to compare two things make sure you make it clear which you are talking about. A question may give to table of data and then ask you about it. Make sure you only use information from the table. e. g. in a table of the composition of normal breast milk and colostrum, you can see which milk contains more fat, protein and sugar. Your answers should start with â€Å"colostrum has more †¦Ã¢â‚¬ ¦.. than breast milk† or â€Å"breast milk has more †¦Ã¢â‚¬ ¦ than colostrum†. Do not put â€Å"it has more protein. † The person marking cannot guess which you thought had more protein. o The question may ask you to make a comparison about biology you have learned. e. g. the differences between arteries and veins.The clearest way of answering is to make your own table. Make sure the headings are clear. Keep the comparisons of the same feature together. Artery has thick wall thick muscle layer ve in has thin wall very thin muscle A table like the one below will not get any marks as there are no comparisons of the same features. Artery thick wall no valves †¢ veins elastic layer small amount of muscle Extended writing. This means writing several sentences together. e. g. Suggest what happens if excess nitrogen fertiliser is washed into a stream or pond [4] o The mark scheme used for a question like this will have a list of oints that the person marking your answer will use. o There will be more points than there are marks, so you do not need to put them all in your answer. The points for this question could be: – Algae and aquatic plants grow faster using the fertiliser. – Algae cover the water surface. Light cannot pass to aquatic plants lower down. – These plants die. Bacteria of decay feed on the dead plants. – Bacteria increase in numbers. – These bacteria are aerobic. – They use up more oxygen. – There is not enough o xygen for other organisms which live in the water. – These organisms die. The process is called eutrophication. If your answer is something like â€Å"The fertiliser causes low oxygen and it affects animals in the water. † you will not get any marks. The answer is much too vague, in other words it is not precise. I your answer is something like â€Å"The animals do not have enough oxygen for their respiration and they die. † you will get some marks. Paper 2 tips †¢ †¢ †¢ †¢ †¢ †¢ Most of the questions are short answers. This means that you writing mainly one word or one sentence answers worth one mark. [1]. Longer answers will need two or three sentences. Check the number of marks.Check the number of command words, do you have to do one or two things. Use the lines given. Do not write too much. Check if you are asked for an actual number of answers. Only give that number. Use the numbered lines and give one answer per number. There will be a few parts of questions that need extended writing. These will have four [4] or [5] marks. The question will often be related to some information you are given. You will need to write four or five sentences in an order that makes sense. You can think of it like â€Å"telling a story†. Remember to refer to any information you are given.Paper 3 tips †¢ †¢ †¢ †¢ †¢ There is more to read in this paper. Many questions will be one, two or three sentence answers. Check the number of marks. Check the number of command word – do you have to do one or two things Check if you are asked for an actual number of answers. Only give that number. Use the numbered lines and give one answer per number. There are questions that may start in one part of the syllabus and link to another, e. g. the information could be about the animals in a particular habitat and what they eat. The first parts of the question might be about the food chains or food webs whic h include these animals.Another part of the question could be about the structure of one of the animals or about factors in its environment. You are likely to have questions about events and situations that are new to you. Do not be put off. The question will tell you all you need to know. What you need to do, is show that you can connect the biology you have learned with the new facts. e. g. you may not have learned anything about how cats inherit the length of their fur. o The question tells you that the alleles for fur length are co-dominant. o The question tells you the fur length of pure bred parents are long and short. You know that the offspring of cross breeding are heterozygous for fur length. o You know from your genetics lessons that for features controlled by co-dominant alleles, both alleles are expressed in the offspring. o You know enough to work out that the fur length of the offspring will be medium length. You are likely to be asked to interpret unfamiliar data, e. g. result from an experiment you may not have carried out or could not be carried out in a school. Do not be put off. Follow the same rules as before. There will always be enough information in the question for you to answer it. †¢ †¢General Tips for Practical Papers †¢ †¢ †¢ †¢ Look to see how many marks are given for each question. Divide the time of your examination in proportion to the marks given. Whichever paper you do the same rules for recording observations. Use the same rules as in the tips for written papers for tables, graphs, calculations and comparisons. Recording your observations †¢ You can record as: o statements in writing o as tables o drawings †¢ Neat work helps to keep you calm and feeling in control. †¢ Use all the space available on the paper for your observations. †¢ Do not write an explanation until the question asks for one. †¢ Use a sharp HB or B pencil.It can be rubbed out easily if you need to corre ct a mistake. †¢ Don’t forget headings for the columns and the rows or tables or graph axes. Don't forget the units! †¢ Make drawings as big as the space allows. †¢ Use a ruler for labelling lines. †¢ Label in pencil. Planning investigations Some times you are asked to suggest a way of carrying out an investigation or to improve the method that is in the question paper. †¢ When you read through an investigation try to work out three main things: 1. What is being changed – this is called the independent variable, e. g. light 2. What is being measured – this is called the dependent variable, e. . oxygen given off by plant 3. What is being kept the same – these are called the standard or control variables, e. g. type of plant, number of leaves on the plant, environment of plant ,the apparatus used, time for collecting oxygen. †¢ Some investigation needs to have two parts: o the experimental- which is the apparatus used to measur e the process being studied and contains the living organism being tested. o The control. –which will be exactly the same as the experiment except the living organism will be missing or replaced by something non-living. e. g. there would be no plant in one set of apparatus. The control shows that the results are due to the activity of the living organism and is not due to the apparatus or an environmental factor. Tips for paper 5 In paper 5 you are following instructions, using laboratory equipment, making observations, recording results and drawing conclusions. †¢ Start by reading the entire first question. †¢ Think about the apparatus needed for each step and imagine using it in your mind. †¢ Check the time to be allowed and imagine following the instructions. †¢ Do the same when you are ready to begin the next question. Following the instructions †¢ Follow the instructions for practical methods exactly.If you make a change in the method you can alt er the results. †¢ Do not take short cuts. †¢ Always label test tubes and other containers to help you remember which is which. †¢ If you are told to â€Å"Wash the apparatus thoroughly after each use† make sure you do. If there is anything left in the apparatus the next stage may not work. †¢ If you have to measure a specimen make sure you draw a line on your drawing to show where you made our measurement. †¢ You will get marks for following instructions accurately. Recording your observations †¢ Do not forget that observations can be seen, heard, felt and smelled. †¢ e. g. olour, fizzing, warming, smell of a flower, texture (feel) of a fruit. †¢ You can always something to observe, so make sure you record something for each observation. †¢ Write down exactly what you observe. †¢ e. g. if you add a drop of iodine to a drop of starch solution on a white tile, the colour changes. o You should write â€Å"the colour changed fro m yellow to black. † o If you write â€Å"it turned black† you have not given all the information. o If you add iodine to a drop of water on a white tile. o You should write down ‘the colour stayed yellow. ’ o If you write ‘the colour stayed the same’, or ‘no change’, you have left information out.Conclusions †¢ Use your own results for your conclusions. †¢ Do not write the conclusion you have learned from a class experiment or from theory. E. g. in an investigation you test drops of a mixture of sodium chloride, amylase and starch solution with iodine once a minute for eight minutes. Then you repeat this with a mixture of water, amylase and starch solutions. o The blue/black colour might disappear sooner in one test tube than the other. o Even if you know that sodium chloride usually makes amylase work faster, you must write down the results from YOUR investigation. You must draw conclusions from YOUR results. o If the c olour in both tubes changes at the same time, the conclusion has to be that the sodium chloride made no difference. That is the correct conclusion drawn from your observations. Tips for paper 6 In this paper you are making observations from information given in the paper, recording results and drawing conclusions. Try to imagine doing the practical which has produced the results in the questions. Recording observations †¢ All of your observations are either measurements that you make or diagrams on the paper. †¢ Write down exactly what you see.Making measurements †¢ Make your measurements as accurate as you can. Measure to the nearest unit e. g. mm. Do not try and â€Å"guess† 0. 5mm. †¢ Make sure you put units! †¢ If you have to make calculations use the blank pages within the paper. Do not write in the margin. †¢ Write neatly and show your working. The person marking your paper might be able to give you marks for knowing what to do if you make a mistake or do not finish the calculation. Conclusions †¢ Use your measurements or observations or on the results given in the question for your conclusions. †¢ Do not rely on something you have learned as â€Å"the right answer†.

General Advice †¢ Answering questions. The questions are meant to let you show the biology you know. There are no trick questions. When you are writing your answers remember that another person has to be able to read it. o o o o o o o o Do not waste time by writing out the question before you start to answer. Keep your handwriting clear and legible. Keep you answer in the lines on the question paper.If you write in the margin, at the bottom of a page, or on blank pages, part of your answer might be missed. If you have to cross out something, put a line through, but do not scribble all over it. If you have to use a different space to write another answer to one you have crossed out, then put a note to say where it is, e. g. answer on page 5 Written papers are now marked on computer screen so your written paper will be scanned. If you write on the margin the scanner may not be able to copy this. Try to be precise, in other word be accurate in what you say. Read also Lab 2 BiologyUsing biological terms correctly can help. Do not use word like â€Å"it†, â€Å"they†, â€Å"effect†, â€Å"affect† without any more explanation. A sentence like â€Å"It has an effect on the body† or â€Å"They affect the process† does not say anything. – If you use the word â€Å"it† or â€Å"they â€Å"– think WHAT? – If you use the word â€Å"affect† or â€Å"effect† – think HOW? – e. g. State why magnesium ions are important for healthy plant development. [1] – â€Å"it are needed by the plant† is true but too vague. – â€Å"They are needed by the leaves† is still too vague – Ask yourself: What is it or they? What is the â€Å"need†? â€Å"Magnesium is needed to make chlorophyll† is a better answer – â€Å"Magnesium is part of a chlorophyll molecule. † Good answer! †¢ Terms. These are the n ames used in biology. These will be used in questions. You will get more marks if you can use them correctly in you examination. Ask your teacher if you are unsure of the different meanings between biological terms. o o Try to use the correct spelling. The person marking your answer will try to recognise what word you mean, but if the spelling is too wrong, then they cannot allow you a mark. Some biological terms have very similar spelling.One example is â€Å"ureter†, urethra† and â€Å"uterus†. If your mis-spelling is â€Å"uretus†, it could be â€Å"ureters† or â€Å"uterus†. Other common examples are ovum, ova, ovary and ovule, testes and testa; sucrose and sucrase. Do not try to mix the spellings of two words when you are not sure which of them is the correct answer, e. g. meitosis, when you are not sure whether the answer is mitosis or meiosis, or urether, when you are not sure if the answer is ureter or urethra. You need to check caref ully that you have used the right word when similar terms are used in the same topic , e. g. urea and urine, ureter and urethra. semen and sperm o o †¢ Writing in you own words. You sometimes have to write two or more sentences to answer a question. o o Use short sentences. If you write long sentences you can get mixed up. It is hard to find correct statements in a muddled answer. You are often asked to write down something you have learned. Make sure you have learnt the meanings of the common terms used in biology, e. g. photosynthesis, osmosis, fermentation. In the revision checklist there is a list of the terms which you should be able to â€Å"define†. You also need be able to write down the meaning of more complicated ideas, e. g. evel of organisation, natural selection, global warming, eutrophication. o What you should look for in a question 1) †¢ †¢ †¢ †¢ †¢ The number of marks. In multiple choice questions there is only one mark for a cor rect answer. Other sorts of question show how many marks at the end of each part like this [2]. The number of marks helps you decide how much to write. The number of marks is a guide to how long to spend on each question or parts of a question. If you allow about 1 minute per mark then you should finish in time to check your answers. Do not waste time and write long answer for a question which has [1].You will only get one mark even if the rest of the answer has correct statements. If there are two or more marks do not write the same thing in two different ways, e. g. The leaf is very large. The leaf has a large surface area. The instructions. These are called command words and tell you what to do. If a question says â€Å"Show your working† when you have to do a calculation, then write down the stages of your calculation to show how you got your answer. Even if you get the final answer wrong, you may be given a mark for knowing what to do. If a question asks you to â€Å"Na me† or â€Å"State† two things only the first two will be marked.Use the numbered lines for your answers if they on the question paper. If you write more than two and the first is correct but the second one is wrong, you will only get the mark for the first one. Even if the third answer is correct, it will not be marked. Some questions have two commands in the question, for example â€Å"Predict† AND â€Å"Explain† †¦. † This means you have to say what you think will happen AND then say why you think it will happen. The Revision Checklist has a list of terms used in biology papers to tell you what to do in an answer (section 4. 3 Command words and phrases).General Biology Ii Study Guide (Online Class)Make sure you know what these terms mean. e. g. â€Å"Name the process by which green plants make sugars†, all you need to write for your answer is â€Å"Photosynthesis†. A question which asks you to â€Å"Define photosynthesis† , would expect you to write one sentence such as â€Å"The process by which green plants use light energy to make sugars†. What the question is about. Make sure you know which part of your biology is being tested Read the whole of a question carefully before you begin to answer it. Some of the parts have similar answers so you need to work out the difference between them.If you write exactly the same thing in different parts of the same question, then only one of them might be a correct answer.

You do not have to know chemical symbols for equations of the processes in biology.But it will help you to understand them if you do. o If you are asked to give either a word or a symbol equation, do not combine symbols and words in the same answer – If you have to give the word equation for anaerobic respiration by yeast, write: o o Glucose > carbon dioxide +ethanol + energy If you have to give the chemical equation for anaerobic respiration by yeast, write C6H12O6 > 2C2 H5 OH + 2CO2+ energy Do not write something like gluco se > CO2 + ethanol and energy †¢ Make comparisons. If you are asked to compare two things make sure you make it clear which you are talking about. A question may give to table of data and then ask you about it. Make sure you only use information from the table. e. g. in a table of the composition of normal breast milk and colostrum, you can see which milk contains more fat, protein and sugar. Your answers should start with â€Å"colostrum has more †¦Ã¢â‚¬ ¦.. than breast milk† or â€Å"breast milk has more †¦Ã¢â‚¬ ¦ than colostrum†. Do not put â€Å"it has more protein. † The person marking cannot guess which you thought had more protein. o The question may ask you to make a comparison about biology you have learned. e. g. the differences between arteries and veins.The clearest way of answering is to make your own table. Make sure the headings are clear. Keep the comparisons of the same feature together. Artery has thick wall thick muscle layer ve in has thin wall very thin muscle A table like the one below will not get any marks as there are no comparisons of the same features. Artery thick wall no valves †¢ veins elastic layer small amount of muscle Extended writing. This means writing several sentences together. e. g. Suggest what happens if excess nitrogen fertiliser is washed into a stream or pond [4] o The mark scheme used for a question like this will have a list of oints that the person marking your answer will use. o There will be more points than there are marks, so you do not need to put them all in your answer. The points for this question could be: – Algae and aquatic plants grow faster using the fertiliser. – Algae cover the water surface. Light cannot pass to aquatic plants lower down. – These plants die. Bacteria of decay feed on the dead plants. – Bacteria increase in numbers. – These bacteria are aerobic. – They use up more oxygen. – There is not enough o xygen for other organisms which live in the water. – These organisms die. The process is called eutrophication. If your answer is something like â€Å"The fertiliser causes low oxygen and it affects animals in the water. † you will not get any marks. The answer is much too vague, in other words it is not precise. I your answer is something like â€Å"The animals do not have enough oxygen for their respiration and they die. † you will get some marks. Paper 2 tips †¢ †¢ †¢ †¢ †¢ †¢ Most of the questions are short answers. This means that you writing mainly one word or one sentence answers worth one mark. [1]. Longer answers will need two or three sentences. Check the number of marks.Check the number of command words, do you have to do one or two things. Use the lines given. Do not write too much. Check if you are asked for an actual number of answers. Only give that number. Use the numbered lines and give one answer per number. There will be a few parts of questions that need extended writing. These will have four [4] or [5] marks. The question will often be related to some information you are given. You will need to write four or five sentences in an order that makes sense. You can think of it like â€Å"telling a story†. Remember to refer to any information you are given.Paper 3 tips †¢ †¢ †¢ †¢ †¢ There is more to read in this paper. Many questions will be one, two or three sentence answers. Check the number of marks. Check the number of command word – do you have to do one or two things Check if you are asked for an actual number of answers. Only give that number. Use the numbered lines and give one answer per number. There are questions that may start in one part of the syllabus and link to another, e. g. the information could be about the animals in a particular habitat and what they eat. The first parts of the question might be about the food chains or food webs whic h include these animals.Another part of the question could be about the structure of one of the animals or about factors in its environment. You are likely to have questions about events and situations that are new to you. Do not be put off. The question will tell you all you need to know. What you need to do, is show that you can connect the biology you have learned with the new facts. e. g. you may not have learned anything about how cats inherit the length of their fur. o The question tells you that the alleles for fur length are co-dominant. o The question tells you the fur length of pure bred parents are long and short. You know that the offspring of cross breeding are heterozygous for fur length. o You know from your genetics lessons that for features controlled by co-dominant alleles, both alleles are expressed in the offspring. o You know enough to work out that the fur length of the offspring will be medium length. You are likely to be asked to interpret unfamiliar data, e. g. result from an experiment you may not have carried out or could not be carried out in a school. Do not be put off. Follow the same rules as before. There will always be enough information in the question for you to answer it. †¢ †¢General Tips for Practical Papers †¢ †¢ †¢ †¢ Look to see how many marks are given for each question. Divide the time of your examination in proportion to the marks given. Whichever paper you do the same rules for recording observations. Use the same rules as in the tips for written papers for tables, graphs, calculations and comparisons. Recording your observations †¢ You can record as: o statements in writing o as tables o drawings †¢ Neat work helps to keep you calm and feeling in control. †¢ Use all the space available on the paper for your observations. †¢ Do not write an explanation until the question asks for one. †¢ Use a sharp HB or B pencil.It can be rubbed out easily if you need to corre ct a mistake. †¢ Don’t forget headings for the columns and the rows or tables or graph axes. Don't forget the units! †¢ Make drawings as big as the space allows. †¢ Use a ruler for labelling lines. †¢ Label in pencil. Planning investigations Some times you are asked to suggest a way of carrying out an investigation or to improve the method that is in the question paper. †¢ When you read through an investigation try to work out three main things: 1. What is being changed – this is called the independent variable, e. g. light 2. What is being measured – this is called the dependent variable, e. . oxygen given off by plant 3. What is being kept the same – these are called the standard or control variables, e. g. type of plant, number of leaves on the plant, environment of plant ,the apparatus used, time for collecting oxygen. †¢ Some investigation needs to have two parts: o the experimental- which is the apparatus used to measur e the process being studied and contains the living organism being tested. o The control. –which will be exactly the same as the experiment except the living organism will be missing or replaced by something non-living. e. g. there would be no plant in one set of apparatus. The control shows that the results are due to the activity of the living organism and is not due to the apparatus or an environmental factor. Tips for paper 5 In paper 5 you are following instructions, using laboratory equipment, making observations, recording results and drawing conclusions. †¢ Start by reading the entire first question. †¢ Think about the apparatus needed for each step and imagine using it in your mind. †¢ Check the time to be allowed and imagine following the instructions. †¢ Do the same when you are ready to begin the next question. Following the instructions †¢ Follow the instructions for practical methods exactly.If you make a change in the method you can alt er the results. †¢ Do not take short cuts. †¢ Always label test tubes and other containers to help you remember which is which. †¢ If you are told to â€Å"Wash the apparatus thoroughly after each use† make sure you do. If there is anything left in the apparatus the next stage may not work. †¢ If you have to measure a specimen make sure you draw a line on your drawing to show where you made our measurement. †¢ You will get marks for following instructions accurately. Recording your observations †¢ Do not forget that observations can be seen, heard, felt and smelled. †¢ e. g. olour, fizzing, warming, smell of a flower, texture (feel) of a fruit. †¢ You can always something to observe, so make sure you record something for each observation. †¢ Write down exactly what you observe. †¢ e. g. if you add a drop of iodine to a drop of starch solution on a white tile, the colour changes. o You should write â€Å"the colour changed fro m yellow to black. † o If you write â€Å"it turned black† you have not given all the information. o If you add iodine to a drop of water on a white tile. o You should write down ‘the colour stayed yellow. ’ o If you write ‘the colour stayed the same’, or ‘no change’, you have left information out.Conclusions †¢ Use your own results for your conclusions. †¢ Do not write the conclusion you have learned from a class experiment or from theory. E. g. in an investigation you test drops of a mixture of sodium chloride, amylase and starch solution with iodine once a minute for eight minutes. Then you repeat this with a mixture of water, amylase and starch solutions. o The blue/black colour might disappear sooner in one test tube than the other. o Even if you know that sodium chloride usually makes amylase work faster, you must write down the results from YOUR investigation. You must draw conclusions from YOUR results. o If the c olour in both tubes changes at the same time, the conclusion has to be that the sodium chloride made no difference. That is the correct conclusion drawn from your observations. Tips for paper 6 In this paper you are making observations from information given in the paper, recording results and drawing conclusions. Try to imagine doing the practical which has produced the results in the questions. Recording observations †¢ All of your observations are either measurements that you make or diagrams on the paper. †¢ Write down exactly what you see.Making measurements †¢ Make your measurements as accurate as you can. Measure to the nearest unit e. g. mm. Do not try and â€Å"guess† 0. 5mm. †¢ Make sure you put units! †¢ If you have to make calculations use the blank pages within the paper. Do not write in the margin. †¢ Write neatly and show your working. The person marking your paper might be able to give you marks for knowing what to do if you make a mistake or do not finish the calculation. Conclusions †¢ Use your measurements or observations or on the results given in the question for your conclusions. †¢ Do not rely on something you have learned as â€Å"the right answer†.
