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

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

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

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

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

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 activity, learners conduct a simple test to find their blind spot.

In this activity, learners control the (apparent) size of a hole with their brain.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

In this quick activity, learners practice locating a constellation in a map of very dark skies.

Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

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

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

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.

Learners make a circuit board that has questions and answers. When the correct answer is chosen for a question, a circuit is completed and a light illuminates.

Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.

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 demonstration (18th on the page), learners conduct a simple test to explore how the cornea refracts light, which is further bent by the eye lens through a process known as accommodation.
