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 quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

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

In this activity, learners create their own obstacle course based on Bernoulli's Principle and try to get a floating ball from the start of their course to the finish line.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

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

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

In this activity, learners construct a simple air pressure launcher for paper rockets.

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

Learners follow the template to build and fly a paper helicopter.

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