Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.

The demonstration/experiment provides quick proof that air has mass.

In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

A group of learners models the Sun shining on the Earth. By rotating the Earth, they demonstrate how the Sun only shines on a portion of the Earth at a time.

Are balloons porous or non-porous? In this activity, learners watch an entertaining Mr. O video and conduct a simple experiment to find out.

This magic trick is based on how computers detect and correct data errors.

In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

Learners complete two simple experiments to prove the existence of air and air pressure which surround us.

This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

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

In this activity, learners create a water prism to break light into the seven colors of the rainbow.

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 activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

This activity generates learner excitement about light through the creation of a room-sized rainbow.
