Now it's time to test your hypothesis. This is done through experimentation. Start by explaining your procedure. Remember to keep your experiment fair and unbiased and watch those variables (change only one thing at a time). After you have your process figured out, make a list of materials you will need. Now you can conduct your experiment. Repeat your experiment several times to validate your findings. Keep careful notes and data.
Collecting data is an important part of your experiment. Be accurate and organized when collecting data. How will you collect this data: laboratory notebook OR graphs OR tables OR photos OR all of the above. Plan ahead.
