Present these demonstrations in front of your class to excite your students about learning core physics concepts.

• Contents include two polarized filters, four transparent shapes and a demonstration guide

Set up and execution are simple, so you can spend more time engaging your students. Ideal for introducing a unit or using as reinforcement after a lesson, these demos are available for all fundamental physical science topics.

A simple, but powerful demonstration of polarization, this demo features two 15cm diameter polarization filters mounted on a base slightly off center from each other. Placed around their edges, a 360° protractor allows students to easily see what happens when the filters are perpendicular to each other. Also included are four transparent shapes that can be squeezed to show how a polarized filter can be used to see stress fractures in materials.
