Method 1: Making a Hypothesis and Defining Variables and Controls.
Students will need an explanation of variables and control groups. Go over these concepts with your students before they try to form their hypotheses. See the Variables Lesson for ideas.
This guide will help you steer your students through the process of coming up with a good question to investigate for an Earth science fair project, designing a way to test that question, and creating a display to share findings and conclusions. The process begins with each student deciding on what he or she finds really interesting in the natural world. Use the navigation bar, above to navigate your way through each step.
