In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.

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.

In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

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

In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

In this activity, learners will explore ways static electricity interacts with the surroundings of an object. The activity has step-by-step instructions in English and Navajo.

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

In this demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as

In this activity, learners observe what would happen to their bodies if they went to outer space without a space suit.

In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.

En esta actividad, los participantes explorarán las fuerzas de gravedad y la resistencia al aire usando paracaídas.

In this engineering design challenge, learners build an air-powered spinning machine.

In this activity, learners will engineer three different parachutes to test how well each one works.

In this physics activity (page 4 of the PDF), learners will construct their own spiral "snake" and use it to explore the relationship between heat and kinetic energy.

In this activity, learners explore how sound travels through solid objects better than through air. Leaners attach a metal clothes hanger to a piece of string and hold it to their ears.

Capture soap bubble patterns on paper! In this activity, learners can create beautiful pictures from popping soap bubbles.
