In this activity, learners play a game similar to Tic-Tac-Toe. In this version, learners try NOT to get three-in-a-row. The player who gets three-in-a-row first loses!

Los Momentos de Mixing in Math son actividades de 5 a 10 minutos que mantienen a los chicos ocupados, aprendiendo sobre el mundo, y usando matemáticas por su cuenta.

In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

We listen to stereo music systems, tv's, and radios because it simulates being where the sound originates.

In this activity, learners explore static electricity and electrical charges while experimenting with an inflated balloon, unflavored gelatin powder, and a wool sweater.

With a magnet, iron fillings, and a bottle, you can create a cool demonstration about magnetic lines of force: the fillings will arrange themselves within the magnet's magnetic field.

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

In this quick activity, learners explore static electricity using a plastic comb, wool cloth, puffed rice, and a plastic bag.

In this activity (13th on the page), learners complete a simple illusion trick to see through their own hand.

In this activity, learners create an optical illusion by spinning two attached cups. A round ball seems to magically appear when the cups spin.

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en libros de consulta o en línea.

In this physics activity, challenge learners to remove the bottom coin of a stack of nickels without knocking over the stack. Use this activity to demonstrate friction.

What happens when two wave pulses meet in the middle? Send waves down a spring to watch them travel and interact.

Can you deceive your eyes? When your eyes work normally, you see a nice 3 dimensional picture, but what happens when each eye sees something different?

This perception trick focuses on conflicting information to the brain...instead of trying to see two images, you're trying to get a bright spot by overlapping the image you see through two tubes.

In this quick and simple activity about reflexes (third activity on the page), learners conduct a simple test to explore the knee jerk reflex, typically conducted at the doctor's office.

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.

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.

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.

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.
