In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.

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.

This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

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

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

A magic lantern is a light that projects an image onto a screen.

In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

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.

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.

This activity guide includes instructions for building a spectroscope using a standard classroom overhead projector.

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

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

In this activity, learners will explore light and rainbows with this easy setup! Learners will only need a cup of water, some paper and a flashlight.
