A scientific method is a a way to investigate a scientific problem. Although the order of steps can vary, the tasks performed during each step is often the same. During which step would a scientist collect data?

• Developing a plan

• Forming a hypothesis

• Testing the hypothesis

• Communicating the results

Why is it important to have more than one trial in an experiment?

• The results should differ each time.

• One of the trials will support your hypothesis.

• The conditions in an experiment are very different in every trial.
