How to Investigate
What do you need to do for your science investigation ???
I expect students to write their reports with the following headings:
- Your teacher will tell you the purpose or aim of the investigation.
- You should already know something about the topic you are investigating and
- you can do some research for your homework.
- Although you may not get any marks for this section, if you do not know anything about the topic you will be unable to write a sensible hypothesis.
- This should have two parts to it:
Predict what will happen in your experiments
Explain why you think your prediction is right. (do make this scientific)
- Just write a list of what you need.
- Your instructions should be clear enough for another pupil to do the experiment.
- Remember to include the safety instructions.
- If there is nothing dangerous, say so.
- Remember that it must be a fair experiment
- explain how you are going to make it fair.
- You should list the variables which are important in this investigation:
the “independent variable” (the one you are testing)
the “dependent variable” (the one you are measuring)
the “controlled variables” (all the other variables must be kept constant)
- You will probably have a table of results and
- some charts or graphs to show what happened
- Make sure that you write down what the charts and graphs show even if it is obvious.
- Say whether your prediction was true or false
- Explain what happened in the experiment.
- Say how accurate your experiment was
- Write down any improvements which you can think of.
