In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of 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 investigate the reflective properties of light and mirrors as they make a kaleidoscope.

In this activity, young learners will explore light and darkness through flashlight play.

This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.

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

In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.

An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.

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.

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

In this activity, learners investigate the effect of heat on a reaction.

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