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, learners make their own heat waves in an aquarium.

In this activity, learners explore the invisible infrared radiation from an electric heater.

In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.

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 related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.

In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.

In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.

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

In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

In this activity, learners use simple materials to create giant bubbles.
