See what force a magnet has on a wire that has current running through it: will it push it, pull it, or will nothing happen? This is the foundation of a simple electric motor.

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

Balance a ball in the air with a hair dryer! This Exploratorium produced activity shows learners concepts like lift and air streams. You can try many different angles, speeds, and ball types.

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

Which one of your eyes are dominant? Do they act independently or are they equally "in control?" This activity explores how your eyes work (or don't work) together.

Learners compare the properties of two balls that appear identical. One ball bounces, while the other ball "thuds." The “bounce” ball is made of the polymer polybutadiene (-C4H4-).

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 this activity, learners cook amino acids and sugar to explore the range of aromas released.

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

Spin in an office chair holding milk jugs! Plus, learn physics. Very fun (but stay safe) activity from the Exploratorium Science Snacks series.

A simple, yet fun activity that lets learners find the center of balance of a ruler (or any long thin object). Developed by the Exploratorium and no assembly needed.

Learners press their fingertip onto a clean Plexiglas sheet. The fingerprints are then revealed as learners dust over the print with fingerprint powder.

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.

Here's a very simple activity if you have paper and scissors: make one cut, unfold, and you have a beautiful star! A great way to learn about polygons and origami mathematics.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

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.

Your tongue can sense about 6 different flavors (salty, sweet, bitter, sour, umami/savory, and fat), but your nose provides a lot more "taste" information than you realize when you eat.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

Exploring the Solar System: Solar Eclipse” is a hands-on activity demonstrating how the particular alignment of the Sun, Earth, and Moon can cause an eclipse.

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