In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

"Molecules in Motion" explores how materials behave and change in a vacuum.

In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

In this activity, learners discover a trick to release the air out of a balloon without popping it.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In this weather-related activity, learners make a portable cloud in a bottle.

In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.

In this activity, learners construct a simple air pressure launcher for paper rockets.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

In this collection of demonstrations, learners explore Newton's Laws of Motion.
