Scientific Method

1. Make observations and ask a question.

  • Questions about things that interest you are the best!

2. Form a hypothesis.  A hypothesis is a prediction of what will happen in your experiment.

  • Write an "If ... then..." statement.  For example: "If I soak the beans in vinegar overnight, they will sprout more quickly than beans soaked in water overnight."

3. Design an experiment that will test your hypothesis.

  • Repeat your test several times, or include a large sample size.
  • Include a control group as well as an experimental group.
  • Make a detailed list of materials you need.
  • Write a detailed procedure, step by step.

4. Gather data during your experiment.

  • Keep a careful record of your observations and measurements.
  • Take photos of your experiments.

4. Draw conclusions.

  • Look at your data and decide whether or not it supports your hypothesis.  Don't worry if your hypothesis was not correct; scientists often learn more from surprising results!

5. Share what you learned.
