In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

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

In this activity, learners work in pairs to measure each other's ankles with lengths of string.
