Organisms require cellular division and differentiation for growth, development, repair and sexual reproduction. In this unit, students investigate the biochemical and cellular systems and processes involved in the transmission of genetic material to the next generation of cells and to offspring. They consider different patterns of inheritance by analysing the possible genotypes and phenotypes of offspring. Students link their observations to explanatory models that describe patterns of inheritance and explore how the use of predictive models of inheritance enables decision making. Students investigate the genetic basis for the theory of evolution by natural selection through constructing, using and evaluating explanatory and predictive models for gene pool diversity of populations. They explore genetic variation in gene pools, selection pressures and isolation effects in order to explain speciation and extinction events and to make predictions about future changes to populations. Through the investigation of appropriate contexts, students explore the ways in which models and theories related to heredity and population genetics, and associated technologies, have developed over time. They investigate the ways in which science contributes to contemporary debate about local, regional and international issues, including evaluation of risk and action for sustainability, and recognise the limitations of science to provide definitive answers in different contexts. Students use science inquiry skills to design and conduct investigations into how different factors affect cellular processes and gene pools; they construct and use models to analyse the data gathered; and they continue to develop their skills in constructing plausible predictions and valid, reliable conclusions. Unit 4 – Surviving in a changing environment In order to survive, organisms must be able to maintain system structure and function in the face of changes in their external and internal environments. Changes in temperature and water availability, and the incidence and spread of infectious disease, present significant challenges for organisms and require coordinated system responses. In this unit, students investigate how homeostatic response systems control organisms’ responses to environmental change – internal and external – in order to survive in a variety of environments, as long as the conditions are within their tolerance limits. Students study changes in the global distribution of vector‐borne infectious diseases. They consider the factors that contribute to the spread of infectious disease and how outbreaks of infectious disease can be predicted, monitored and contained. Through the investigation of appropriate contexts, students explore the ways in which models and theories of organisms’ and populations’ responses to environmental change have developed over time. They investigate the ways in which science contributes to contemporary debate about local, regional and international issues, including evaluation of risk and action for sustainability, and recognise the limitations of science to provide definitive answers in different contexts. Students use science inquiry skills to investigate a range of responses by plants and animals to changes in their environments; they construct and use appropriate representations to analyse the data gathered; and they continue to develop their skills in constructing plausible predictions and valid conclusions. How do I achieve to the best of my ability? This year is designed to prepare you for further study and to equip you with the skills needed when you leave school. You may find that the material is presented at a faster pace and there is more responsibility on your part to keep up by regularly studying at home. Many students in the past have said that they wished they had studied harder from the beginning of the year. In particular, Biology is a technical subject and has a large and complex vocabulary, which must be mastered bit by bit. So to help you, here are some suggestions: Get organised. Have a master at home file for filing your notes and worksheets, set up topic by topic. After each topic put your notes into the master file and keep the topics separated by dividers. A definitions book is helpful. An exercise book works well. Where possible try to write the meanings in your own words. Make sure you understand everything you write in this book. Use the summary at the end of each chapter and the glossary at the end of the textbook to help you to compile your book. Study time. Although you will not have a lot of homework and assignments, you are expected to spend 3 hours a week on Biology. This time of study and revision is essential if you are to keep up with all of the information presented to you. Suggested things to do during this time: Read over the work covered in class that day – your notes and text book. Write new words and definitions into your definitions book. Write down anything you don’t understand and be sure to ask the following lesson. Review the work to date on the topic (look back a few lessons), trying to link concepts and information together. Test yourself on the work to date. Use your revision book. Class time. Make the most of class time – it is much harder to catch up if you waste this time. You can make good use of class time by: Paying attention. Getting involved in class: answering and asking questions, listening to other student’s answers, asking for help. Working quickly and quietly during practical sessions. Keep accurate records of your results, regardless of whether it is for assessment or not. Bringing your textbook to class. You can underline key concepts and write questions in the margin. Assignments. Start early and have your work totally ready to hand in on time (i.e. name on it, stapled, etc) well before coming to school on the due date. Exams. Go over your notes and textbook. Do not over study the areas you find easy and ignore the harder areas. Aim for a good working knowledge in all areas. Practice writing extended answers – they need careful planning and a logical order. Don’t write the topic out – just begin with a short topic sentence. End with a brief conclusion. Keep your sentences short – one sentence – one fact. Answer the question in the order it was asked – it is acceptable to partition your answer if the question was partitioned, to use dot points, well labelled and informed diagrams, tables (esp. for comparisons), etc. http://writing.colostate.edu/index.cfm AND http://www.lc.unsw.edu.au/onlib/exkey.html Date Visited: 16 December 2009 Answering Exam Questions Comment on To discuss, criticise, or explain the meaning as completely as possible Compare To show the similarities between two or more objects, theories, events, concepts, applications or explanations. Contrast To compare by showing the differences between two or more objects, theories, events, concepts, applications or explanations. Define To give the formal meaning by distinguishing it from related terms. Include elaborations and examples where applicable. Describe To write a detailed account or verbal picture in a logical sequence or story form; noting physical and sometimes chronological details (eg. describe the trends in a graph) Discuss To present arguments for and against a point of view and reach a conclusion. The arguments must be supported with appropriate evidence. Evaluate Requires a judgment about which theory, application, approach etc. is superior and why. To give an opinion, supported by some expert opinions, of the truth or importance of a concept. Show the advantages and disadvantages. Explain Requires an analysis of cause-and-effect or explanation of the reasoning process – answers ‘why’. Explore the rest of the question to see if there is an additional focus or link to other ideas, objects or theories. Illustrate To explain or make clear by concrete examples, comparisons and/or analogies. List To produce a list of words, sentences or comments. Can be in dot point form. Outline To give a general summary. It should contain a series of main ideas supported by secondary facts. Show the organisation of the idea. Name Eg: Name the process – photosynthesis, respiration, transpiration etc. Relate To show the connection between things, telling how one causes or is like another. State To describe the main points in precise terms. Use brief, clear sentences. Omit details or examples. Summarise To give a brief, condensed account of the main ideas. Chicago Style referencing for reports Murdoch University. Library. 2001. How to Cite References. http://www.murdoch.edu.au/library/find/citation/ (accessed October 27, 2009). CITATION WITHIN THE TEXT There are two options for in text references. Firstly, the reference can be placed at the end of the sentence wholly in parentheses. Alternatively, the author's name may be integrated into the text, and just the date and additional information placed within the brackets. See examples of both of these options in the next section below. There are four common methods of referring to a source document in the text of an essay, thesis or assignment. These methods are: 1. Quoting Quotations must be identical to the original, including punctuation, using a small section of the source. They must match the source document word for word, be enclosed within quotation marks, and must be attributed to the original author with an in text citation. When directly quoting from another source, ensure that the relevant page number(s) are given. Short quotes Larsen (1991, 245) stated that "many of the facts in this case are incorrect". Longer quotes In general, avoid using too many long quotes and remember to introduce or integrate quotations smoothly into the rest of your assignment. 2. Paraphrasing Paraphrasing involves putting a passage from the source material into your own words. A paraphrase must also be attributed to the original source with an in text citation. When paraphrasing, keep the meaning the same but do not use the original wording. The purpose of paraphrasing is that it flows better with your own writing. You generally need to change both the sentence structure and the expression, using synonyms or alternative expressions. Paraphrased material may be as long (or even longer) than the original source material. However, it is often shorter than the original passage, taking a larger section of the source and condensing it slightly. When paraphrasing, you must also include the page number(s) which relate to portion of the text that you have used. Original - "Named for James Brady, the White House press secretary who was shot and wounded by John Hinckley Jr. during the attempted assassination of President Ronald Reagan in March 1981, the Brady Bill establishes a national waiting period and background check for the purchase of a handgun" (Bender 1995, 137). Paraphrase - Bender (1995) explains that the introduction of a waiting period and a background check for people buying handguns in the US, is due to the Brady Bill. The bill was named after White House aide James Brady, who was wounded during an assassination attempt on President Reagan (137). 3. Summarising Summarising is condensing longer text to a much briefer version. It involves putting the main idea(s) into your own words, including only the main point(s). Once again, it is necessary to attribute summarised ideas to the original source with an in text citation. Summaries are significantly shorter than the original and take a broad overview of the source material. Page numbers should be given when summarising. THE BIBLIOGRAPHY PAY ATTENTION TO THE USE OF PUNCTUATION MARKS All documents cited in your assignment are listed in a single alphabetical list at the end of the assignment. The list is arranged by the author's family name or title if no author is present. The authors' names are given as they appear on the publication you have used. Capitalisation practice also should be consistent. Titles are given maximal capitalisation. All words other than prepositions, conjunctions, and definite and indefinite articles (a, an, the) are capitalised. Journal and book titles are italicised or if handwritten underlined. If any information is missing from the source (make sure you check thoroughly) then just use the information that is available. PRINT DOCUMENTS Books Author, A., and B. Author, eds. Year.
