Try it Yourself

How does light affect your sleep? Design an experiment that you think would work. Suppose you were asked to design an experiment to figure out if sleeping with the light on interrupted your sleep. Or try an experiment about the sleep patterns of people who work the night shift. What would your experiment look like?

Suggested Materials:

• paper

• pencil

1. Devise your hypothesis.

2. What is your procedure? List the steps.

3. How many trials will you do? What is your controlled variable? Your independent variable?

4. Predict what your results will be.

5. Explain what you think you would see.

6. Draw a conclusion.

Note: With your grown-ups’ permission, you might want to conduct your experiment on a weekend or a school vacation. Was your prediction correct?
