The Process of the Science Project » Conduct Your Experiment

Follow your experimental design to collect data and make observations.
Be sure to keep a log as you conduct the experiment to record your data, any problems you encounter, how you addressed them, and how these problems might have affected your data. Do not rely on your memory. This log will be used when you write your report.
Remember to change only one variable at a time when experimenting, and make sure to include control experiments in which none of the variables is changed.
Make sure you do sufficient trials in both control and experimental groups to be statistically valid.
