In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

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

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 evaluate the potential performance of air rockets placed inside a wind tunnel.

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.

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this activity, learners examine raindrop bottles (prepared ahead of time) to observe in slow motion the behavior of falling droplets and explore concepts such as drag and terminal velocity.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this activity, learners explore clouds and how they form.

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 activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.
