Week 4 - Science Fair Homework

Science Fair – Week 4:
Continue to research the science behind your topic:
Remember to collect information from a range of sources:
 Websites (note down the name and address of the website in your logbook)
 Books – the library has a whole reference section (note down title, author, publisher and published date in your logbook.)
 Clickview – assessed on the school computers
 Interviews with experts – interviews can help you gather information which you find hard to find somewhere else. It could help you fill the gaps in your knowledge and understanding.
Method:
Plan and write your method for your investigation/experiment. Write down all the materials and equipment you will need. Write this as a list.
Next, write your method. This involves step by step of how you are conducting your experiment. Remember the steps must be in order. Your method must be clear enough for someone else to pick up your method and copy your experiment perfectly.
Draft of my method:



Fair Testing:
Fair testing finds relationships between variables. A single variable is changed while keeping other variables the same.
Identify what the variable (the one thing you are changing) and then observe or measure the change to your results.
Example: Crazy Canisters: we changed one variable, the amount of water used, but kept the amount of baking soda and tartaric acid the same. We then recorded the difference it made to our results.
Fair testing also involves repeating the experiment 3 times (if possible). This allows for you to check if you can get the same results each time and prove the validity of your experiment.
Record: What are your variables:
Which variable are you changing?
Why?
Which variables are you keeping the same? Why?
