Create a painting by blowing air out of a straw. Push liquid acrylic paint around on some watercolor paper by aiming short bursts of air onto the paint puddle.

Learners develop an understanding of air pressure in two different activities.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

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

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.

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 physics activity, learners conduct two experiments to explore free-falling.

In this activity, learners use household materials to investigate and explore their ability to smell an odor.

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.

This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.

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.
