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

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

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 activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

Learners add drops of alginate solution to a solution of calcium chloride. The alginate does not mix with the calcium chloride, but forms soft gel beads.

This is a quick and simple demonstration about reflexes (fourth activity on the page). One learner stands behind a see-through barrier like a window or wire screen.

In this activity, learners create a hearing based memory game that they can share with friends.

In this optics activity, learners discover that when they rotate a special black and white pattern called a Benham's Disk, it produces the illusion of colored rings.

This activity introduces learners to wolf behavior and communication.

In this activity, learners practice drawing 3D structures in two dimensions. Learners draw cube stacks from five different points of view.

The beautiful iridescent colors of a bubble in a can! With this Exploratorium Science Snack, create beautiful soap films on the open end of a can to see beautiful rainbows of color.

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.

In this Bob the Builder(TM)-themed activity, learners go on a nature walk outside and describe what they observe using their senses.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

Audio Boggle is an activity that lets you listen to a track (that you make yourself) and see what you can hear!

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

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 group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.
