In this activity, learners work in NASA teams to build balloon-powered rockets using identical parts and compete to launch the greatest number of paper clips to "space" (the ceiling).

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this activity, learners work in pairs to conduct a series of experiments using a balloon, drinking straw, and paper.

In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

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.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

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 will create a model rocket out of an inflated balloon attached to a straw on a taught string.

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.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.
