In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

In this trick, learners discover how to stick a straw to the palm of their hand, window door, or anywhere using static electricity.

In this activity, learners make their own "tornado" using two soda bottles and water.

In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.

In this activity, learners will engineer three different parachutes to test how well each one works.

This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

In this activity, learners construct paper airplanes that twist and turn.

In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

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.

En esta actividad sobre la exploración e investigación, los aprendices harán ventanas de burbujas.

In this activity, learners turn an ordinary metal coat-hanger into a (very quiet) musical instrument.

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this weather activity/demonstration, learners watch as a ping pong ball is suspended in a stream of air supplied by a hair dryer.

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

In this activity, learners watch a figure "magically" float up through the air.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.
