Refraction with Concave and Convex Lenses

Download Lesson

One of the ways we manipulate light to make it do what we want to do is by using lenses to change the direction of light via refraction. This is some background information for you, the teacher. Allow students to explore the materials, using worksheets for guidance, and then hold a classroom discussion to highlight the main learning points.
