About:

This comprehensive science worksheet covers the foundation of the scientific method for Grades 7–8. Students analyze an experimental scenario about sleep and test performance to identify variables, write hypotheses, calculate averages, and create graphs. The worksheet also addresses scientific theory versus law, the importance of replication and peer review, and how to handle data that doesn't support a hypothesis. Useful for introducing or reinforcing scientific inquiry skills, in-class work, homework, or unit review.
