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

In this activity, learners surprisingly pop balloons without touching them using orange peels. This Mr.

In this activity, learners explore polymer structure and their ability to reform around objects by attempting to stab a wooden skewer through a balloon without popping it.

Learners construct a rocket from a balloon propelled along a guide string.

In this activity, learners use simple materials to construct a balloon-powered pinwheel. The pinwheel is a great way to investigate Newton's Third Law of Motion.

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 activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.

Learners will build a homemade pump using a balloon, a mason jar, and some straws.

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 try to blow up a balloon hanging inside of an empty bottle.

In this math lesson, learners explore the real world meaning of slope. Learners conduct a balloon experiment in which they measure the circumference and flight time of deflating balloons.

In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.
