Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

Learners develop an understanding of air pressure in two different activities.

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

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

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners make optical fibers out of strips of gelatin.
