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.
