In this quick activity, Dracula has a hole in his house and learners help solve the problem by using a mirror and protractor to reflect incoming light out of his house.

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 explore how nanosized structures can create brilliant color.

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

In this activity, learners make their own heat waves in an aquarium.

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.
