Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

In this activity, learners will experiment with water- and air-filled balloons as a way of dampening sound before it reaches their ears.

In this challenge, learners make a helium balloon hover in one spot and then move it through an obstacle course using air currents.

In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.

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

This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

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.

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

Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.

In this activity, learners will make and launch feather rockets. Lerners will use science process skils such as making predictions and measuring while launching the rockets.

In this activity, learners observe what would happen to their bodies if they went to outer space without a space suit.

To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.

Learners follow the template to build and fly a paper helicopter.

En esta actividad, los participantes explorarán las fuerzas de gravedad y la resistencia al aire usando paracaídas.

In this activity, learners will construct an air cannon as a model for the human ear.

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