Air ...What Gives?

I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

If a heavy steel car can't protect you from injury, how can a bag filled with air? The lesson answers this question and many others as young scientists experiment with the impulse and forces related to air bags in automobiles. 

Experiment investigating atmospheric pressure using simple materials.

We all have standards and scientists are no exception. Presentation covers standard temperature, standard pressure, temperature conversions, and absolute zero. It explains pressure using pascals, mm of mercury, atmosphere, and torr, then...

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...

Does it feel a little humid in here? Learners assume the role of water vapor in the atmosphere as they explore the differences between warm and cold air. They roll dice to determine their level of energy, which determines if they...

How can people control a hot air balloon? The simple simulation allows scholars to adjust the payload mass, burner, and vent position on a hot air balloon and observe the changes in velocity and altitude over time. Challenge questions...

[Free Registration/Login Required] Uncover the relationship between pressure, force, and contact area in the context of a fire truck. Play with vehicle mass, number of tires, and guage pressure with this simulation to see what...

Learners complete an experiment in which they demonstrate that air exerts a force. In groups, they create their own siphon and define air pressure. They estimate the time it might take to siphon various amounts of water. They collect,...

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...
