In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

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.

Learners conduct four simple experiments to demonstrate the effects of air pressure.

In this physics activity (page 2 of the PDF), learners will construct their own walkalong glider. They will explore how air, though invisible, surrounds and affects other objects.

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

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

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

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

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

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

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.
