In this activity, learners explore what happens when polarized white light passes through a sugar solution.

This is a great activity about wave interference. Learners will create their own wave machine and discover wave properties through hands-on investigation.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

In this optics activity, learners explore interference by adding wax blocks to a ripple tank.

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.
