In this simple activity, learners investigate refraction by placing a picture of an arrow behind a glass of water.

In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.

Like water drops in falling rain, a CD separates white light into all the colors that make it up.

Learners demonstrate how water can distort, refract and magnify light.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.

In this optics activity, learners explore how light bends and affects what we see.

Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.

In this optics activity, learners make a "light fountain" from a clear plastic bottle, flashlight, and other simple materials.

In this optics activity, learners use paint thinner to make a small jar seem to disappear inside a larger jar.

Can gelatin (like Jell-O ®) change the speed of light?

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

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 (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction.

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

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of
