DUNGOG HIGH SCHOOL SCIENCE DEPARTMENT INDIVIDUAL RESEARCH PROJECT YEAR 10 2014 This project is a compulsory part of the Science course for all students in NSW. Any student who does not complete the task will receive a Board of Studies N award warning letter. Students who do not meet course requirements in Science do not receive a RoSA. Due Dates: Part 1 (Preliminary report) 17th March 2014 Part 2 (Final report plus this booklet) 4th April 2014 Late Policy: If you cannot hand this task in by the due dates you must complete an illness/ misadventure appeal form within two days of the due date or on return to school if absent. The head teacher will consider the appeal and notify you of the outcome. There must be very good reasons for an appeal to be successful. If illness is claimed as a reason for an appeal, a doctor’s certificate will be required. If the appeal is due to absence from school, very good reasons will be required. Appeals involving computer malfunction or lost assignments will not be upheld. It is your responsibility to save and keep multiple copies of your work. Name:_______________________________ 1 Class:________ Choosing a Topic Select a topic that interests you, something that you are prepared to work on for several weeks, at least. Is there a problem that you would like to solve? Start by doing some reading. There are many books and websites available which contain ideas for projects. It is best for you to be CREATIVE and ORIGINAL. Make the project your own unique endeavour. Project Ideas About Plants Most plant investigations would involve too long a time frame for this project. Into everyday problems e.g. What is the best way to remove ink marks from school clothes? Involving Chemistry e.g How can new dyes or indicators be made from natural products? Studying animals e.g. How can I prevent snails from eating lettuce seedlings in my vegetable garden? Of consumer interest e.g. How can you best prevent bread or cheese or yoghurt from going mouldy? Studying electricity e.g How can a lemon or an orange act as a battery to power a clock? For more Ideas See Appendix 1 and the following website has some more ideas http://www.csiro.au/resources/ps1z1.html 2 Planning What to Do What are you actually going to do? What are you going to find out? What measurements and observations will you need to take? What results do you expect to obtain? Which factors will affect the results? Planning your Experiment The hypothesis Form a hypothesis. This is an “educated guess” about what you think will happen in a certain set of circumstances or conditions. You will need to decide what these conditions are. It is important that you keep as many factors the same as possible, so that you can clearly interpret the results. Your hypothesis must be able to be tested. It needs to be simple and very specific. Equipment You will need to decide on the equipment that you are going to use and the method that you will use. The Variables When you carry out an experiment there will be several conditions or factors that could change during the experiment. These factors or conditions are called VARIABLES. Some variables will be kept the same throughout the experiment while others are changed. For your experiment to be a FAIR TEST, as many variables as possible should be kept the same while you change one particular variable. In this way you can sort out which change led to the results that you obtained. If only one variable changes, while all others are kept the same, the results that you can detect must be caused by the variable which has changed. Accuracy When making measurements, you need to be careful to ensure that they are as ACCURATE as possible. To do this, you will need to think carefully about what you are trying to measure, and the tools that are available to use for measuring Repeating an experiment more than once will give you more confidence in your results. It also enables you to detect results that are unusual. You need to keep repeating your experiment until you get several answers which are very similar. 3 Preliminary Report You must complete this sheet and have your project approved by your teacher before starting any experiment. You will not be given approval if your teacher considers it dangerous, impractical, harmful to living things or the environment etc. You also need to have your parent’s approval for your particular project as projects may sometimes involve expenses or inconvenience at home. Keeping a Record An important part of carrying out your investigation involves keeping track of the work that you do and the decisions that you make. You could use One Note on your computer or obtain a book in which you can record your original idea and the comments that other people made when you discussed it with them. Your teacher will probably want to check it from time to time. You will need touse it to keep track of the time you spend on your project. In your log book, record your hypothesis, your research and discussions, the aim, the list of equipment that you need, your method, all results and all other work. If you make changes to the method or if you have problems which need to be overcome, this information should be recorded. Can also include diagrams and/or photos where necessary. Record all your thoughts and ideas in your book. Make notes and comments in your book. It is like a diary. Your Log Book is not your final report. 4 Recording your Results Start thinking about how you are going to report you results. Could you take some photographs to show what happened? Would a graph or a diagram be useful? Can the information be recorded in a table to make comparison easy? Look at the results and think about what they mean? Has your original aim been answered or do you need to carry out further experiments to help you come to a conclusion. Are any of your results unexpected? How can you explain them? You do need to be able to prove that you conducted the experiment. Photographs, even taken on your phone are a great thing to include. Discussion and Conclusion The last part of your project involves a discussion of the results that you obtained. Describe any difficulties that you had carrying out the experiment and interpreting the results. Any suggestions for how the experiment could be improved should be included here too. You also need to outline your research and discuss how it relates to your experiment and your results. Finally, write a conclusion based on the results that you obtained. Aknowledgements It is important in any project that all the help that you received is acknowledged with a bibliograpy. A bibliography is a list of books, magazines, internet sites and other resources you have used to complete a task. A bibliography always comes at the end of a piece of work and is always arranged in alphabetical order. A bibliography must include: the name of the author or editor the publisher of the book the date the item was published the internet address the title of the article “n.d.” stands for ‘no date’ the full title of the book For example: Book Whalley, K. 2003, Science Focus 1, Pearson Longman, Sydney. Webpage Heaps, S. 1996 (updated 2009), ‘History of chemistry ’, Chemistry, Wikipedia. Retrieved 1 January 2014 from http://www.wikipedia.org/chemistry.html Webpage (No Author, no publication date) “Light: The eye and colour vision” n.d., Physclips, UNSW. Retrieved 3 March 2014 from http://www.animations.physics.unsw.edu.au/light/eye-colour-vision/ 5 The Final Report The following is a list of headings that you should use when writing your report. Title Hypothesis Aim Variables o Dependent Variable o Independent Variable o Controlled Variables Equipment Safety Issues Background Information Method Results Graph Analysis Conclusion Bibliography 6 PRELIMINARY REPORT SHEET Name: __________________________ Science Class: _____________ Teacher: ___________________________ Title of Project:______________________________________________________ My Hypothesis: ___________________________________________________________________ Brief description of project: ___________________________________________________________________ ___________________________________________________________________ ___________________________________________________________________ Controlled variables Independent variable Dependent variable (What I will keep the same) (What I will change) (What I will measure) Parent Acknowledgement: I am aware that the science project that my son/daughter is about to commence is a major assessment task and will be used in the calculation of the end of year grade in science.
