In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

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

Students design and build their own parachutes in this hands-on engineering project.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this activity, learners make plates levitate! Learners build "hovercrafts" using simple materials to explore friction and motion.

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.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.

In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.
