In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this activity, learners will test soil content using their sample, some water and a container that seals.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.

In this hands-on activity, learners use heat to shrink samples of polystyrene plastic (#6 recycle code). Learners compare the size and shape of the plastic pieces before and after shrinking.

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.

We're told from a young age that we have 5 senses, but we have many more. One of which is our awareness of our own body part's orientation and position.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

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.

Learners explore how recyclers take advantage of the different properties of materials, such as magnetism and density, to separate them from a mixture.

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

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

Listen to the beat of gravity. By taking two strings with weights tied to them at different, yet uniform intervals, you can hear the uniformity (and rhythm) of gravity's accelerating pull.
