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 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.

This lesson guide includes six simple and quick activities to help learners better understand Bernoulli's Principle.

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.

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

In this activity (page 1 of PDF under SciGirls Activity: Forecasting), learners will construct an air cannon by cutting a hole in the bottom of a bucket and stretching a garbage bag over the other end

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

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

Students design and create their own air-powered rockets, in this hands-on activity.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

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

In this physics activity, learners will build their own parachutes out of tissue paper. They will explore the effects of weight, height, and design on the parachutes' speed and stability.

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

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

In this weather activity, learners build their own wind detector and test for the presence of convection currents in their indoor location.

In this outdoor activity and bingo-like game, learners explore why and how seeds spread far from the plants that produce them.

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.

Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

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
