Hooray! In this design challenge activity, learners invent a device that launches a spoonful of confetti into the air. Learners are encouraged to create the biggest cloud of confetti possible.

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

In this activity, learners watch a figure "magically" float up through the air.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

This is a great activity for investigating the basics of lift and drag as they pertain to flight. Learners will discover how to avoid "taking a nosedive" by building their own paper airplane.

Take the two-straw challenge and discover how pressure affects vacuums! In this activity, learners experiment with drinking through one and two straws, comparing the amount of liquid they can drink.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this dramatic activity/demonstration about phase change and condensation, learners place an aluminum can filled with about two tablespoons of water on a stove burner.

In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.

In this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

In this activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.

In this activity, learners explore Charles' Law in a syringe.

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 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 build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.
