Egg in a Bottle

Using a dry cleaner bag and a blow dryer, create a hot air balloon! The materials list suggests obtaining one dry cleaner bag per student, but since this is probably inconvenient, consider doing this as a demonstration during a lesson on...

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 weather,...

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.

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...

The classic egg-drop experiment gets a new bounce with an activity that asks pairs to design a lander similar to one used to land a rover on Mars within a fixed budget. The activity provides a great introduction to the idea of terminal...

This simulation begins with an exploration of water pressure and atmospheric pressure. In the flow portion, scholars reshape a pipe and see fluid dynamics at work. The water tower portion encourages pupils to determine how water...

Turn up the heat! What happens to the pressure in a closed system as temperature changes? Enhance your chemistry class' understanding of the gas laws with an illustrative interactive. Pupils change the Kelvin temperature before observing...

A teenaged Jack Spangler demonstrates how reducing air pressure in a bottle can pull a boiled egg inside. Then dad does a similar demonstration using liquid nitrogen to reduce the air pressure. Even though the result is the same, the...

Students discuss ways they might visually see pressure differences, and work in groups to create experiments to predict and prove what a change in pressure can do to objects exposed to the change.

Introuduce your scientists to the differences in air at varying altitudes with a colorful explanatory graph. After some discussion, they view unbelievable footage of mountain-climbing Leo Houlding and a narrative about how he might do...
