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

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

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.

In this lab (Activity #1 on page), learners explore how we see color.

In this activity, learners construct a device that allows them to look over ledges or around corners.

In this activity, learners explore the many uses of periscopes and how this simple device was designed and is used in many applications.

In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).

Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.

Look at pictures through different color filters and you'll see them in a new way. People have used color filters in beautiful photography or sending secret messages.

In this quick activity, Dracula has a hole in his house and learners help solve the problem by using a mirror and protractor to reflect incoming light out of his house.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

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 science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this optics activity, learners use water to make a coin "appear" and "disappear." Use this activity to demonstrate how light refracts and introduce light as waves.

In this activity, learners create a water prism to break light into the seven colors of the rainbow.

In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).
