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

In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.

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 activity about light and perception, learners create and observe moire patterns.

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

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