In this activity, learners will explore how light can refract or break apart into different colors.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

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

In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl

In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

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

In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!

Did you know that using a lens one can bend light to make pictures of the world? It's true!

In this activity, learners use Jell-O to explore lenses. Learners cut Jell-O into convex and concave lens shapes and examine how light exits each lens in a darkened room.

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 activity, learners make optical fibers out of strips of gelatin.

This is an activity (located on page 3 of the PDF under Butterfly Wings Activity) about how visible light is affected by tiny nanoscale structures, producing iridescence on butterfly wings, soap bubbl

In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.

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

In this activity, learners explore light, color and rainbows by making their own rainbow glasses.

Light painting is a creative activity that involves creating striking images and illusions using a camera, a light source, and a little practice.

This is an activity about turbidity, or the amount of sediment suspended in water.

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

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