Essential Physics Demo: Polarization

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

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.
