In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

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

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

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 activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

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

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 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.

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

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

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

In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.

In this amazing activity about light and reflection, learners will use a pie plate and reflective strips from a mylar balloon to try to morph their face into a friend's.

In this optics activity, learners build a spy tool to secretly view things over walls or around corners.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan
