Air Expansion and Contraction

Push the envelope with this lesson on atmospheric pressure! Your physics or geology juniors will be amazed at your super-human ability as you demonstrate the breaking of a stick using a newspaper! They also work with peers to construct a...

This presentation is about air. What makes it unique is that, in addition to simply providing information about the components of air and the action of air pressure, it  includes a series of four experiments that bring these...

Up, up, and away! Teach your class the science behind hot air balloons when by showing them the short video segment describing the physics of how they remain in the air and travel distances through different atmospheric...

Investigate what is pushing on us. An intriguing lesson has pupils calculate the amount of force on various squares due to air pressure. Using the data, individuals create a graph in the third lesson of the Up, Up and Away unit...

It's amazing how easy it is to forget that every second of our lives we are being pushed on by an uncountable number air molecules. Explore with your class the concept of air pressure and how it affects our bodies, the earth's...

Middle schoolers, in groups, create experiments to predict and prove what a change in pressure can do to objects exposed to the change. They use AppleWorks to write their hypotheses and the steps they need to conduct the experiment.

Do not let the pressure get to you. The first lesson in a unit of 22 introduces the concept of air pressure. Using background knowledge, the resource gives teachers the information they need to discuss how people measure air pressure and...

Do not let the pressure get to you. After watching a video on calculating values using the pressure formula, pupils work problems on two worksheets. The problems range from finding the pressure, the force, or the area given the other two...

Expanding gases are everywhere, from the kitchen to the cosmos. You've tasted their pleasures every time you've eaten a slice of bread, bitten into a cookie, or sipped a glass of soda. In this chemistry science fair project, you'll...

Love is in the air? Wrong — nitrogen, oxygen, and carbon dioxide are in the air. The final instructional activity in the series of five covers the impact of temperature on gases. Scholars view a demonstration of gas as a type of matter...
