In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.

In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

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 about electricity, learners imagine that they are out in the wilderness and it is getting dark. Their task is to use the materials supplied to build a simple flashlight.

In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

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 construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.

Learners explore their surroundings while reasoning about categories and counting.

In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.

In this activity, learners explore how mirrors reflect light and change the way we see things.

In this activity, learners construct a device that projects images onto a surface, so they can trace landscapes and other sights.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.

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

In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.
