In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.

In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.

This resource contains several mini-explorations using a slide projector as a light source to investigate light and the properties of images.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this activity, learners make a photographic image—without a camera!

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

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 will explore how light can refract or break apart into different colors.

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

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

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 trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

In this activity, learners explore their eye pupils and how they change.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this activity about light and perception, learners create pictures in thin air.

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

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

This activity generates learner excitement about light through the creation of a room-sized rainbow.

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