- How many times to conduct your experiment.
- The number of subjects you will test.
- How long the experiment will last?
- How will you measure the effects of your experiment?
- Where will the experiment be carried out?
Once these decisions have been made you are ready to write your procedure in your log book. The procedure is a set of step by step instructions that you will follow as you carry out your experiment and that another person would be able to follow if they wanted to repeat your experiment.
Once you have written your procedure, it is experiment time!
Follow your procedure and record your results in your log, perhaps in a table or chart. Remember to take any photographs or make any drawings that you may want to use on your display. Repeat your experiment if necessary, this will make your data more reliable.
