In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.

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

In this activity related to flight, learners conduct two simple tests to explore how lift works.

In this quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b

In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.
