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 activity, learners with explore the gases present in air. They will then build their own wind cannons and challenge family and friends to a friendly competition.

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.

What keeps bubbles and other things, like airplanes, floating or flying in the air?

In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.

Is this activity concentrating on physical science, learners build their very own miniature hovercraft out of a paper cup. Using it, they can explore the concepts of friction and force.

In this activity about states of matter, learners get to witness firsthand the awesome power of air pressure. They watch as an ordinary soda can is crushed by invisible forces.

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 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.

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 weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!

In this activity, learners explore why frost forms. They create their own frost using a solution of ice water and salt in a glass.

In this activity about weights and balances, learners create their own balance using paper cups. Then, learners explore how to compare the relative mass of objects.

This is an online game recreating the longest ever (at that point in time) freefall jump by Air Force Captain Joe Kittinger.

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

In this physics activity, learners will explore buoyancy.

In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.
