In this activity, learners overlap the three primary colors to see how all other colors are made.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

Can gelatin (like Jell-O ®) change the speed of light?

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

This is an online game about stopping distance. Learners choose one of three vehicles and one of three speeds.
