What Causes Pressure?

What Causes Pressure?

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope. Learners explore how air molecules move in different scenarios: added pressure, reduced volume of the container, increased heat, etc. Learners will make "beeps" to help the group measure the pressure and hear the difference between low and high pressure. This is a great way to introduce the concept of air pressure and illustrate how it varies with density and temperature.
