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

Learners demonstrate how water can distort, refract and magnify light.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

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 two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

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

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.
