In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

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

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

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

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?

If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

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

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 hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.

In this optics activity, learners build a spy tool to secretly view things over walls or around corners.

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

If you had a long tube with a 5 millimeter wide slit, would you see the entire Golden Gate Bridge?

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

Create an illusion where it appears that your hand has a hole in it. You'll see the results from when one eye gets conflicting information.

In "Exploring the Universe: Exoplanet Transits," participants simulate one of the methods scientists use to discover planets orbiting distant stars.

Make a big canvas of iridescent color with pvc pipe! In this Exploratorium Science Snack, you'll need to cut and assemble some PVC pipe, but the pay-off, the soap-bubble canvas, is big.

Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.

In this optics activity, learners work in pairs to explore how mirrors work. Learners use tape to mark the angles needed to see each other's reflection in a wall mirror.
