Explore air pressure and how it works. In a sealed syringe, as the plunger moves back and forth, the volume of air in the syringe changes. With a large enough syringe, a PocketLab can be placed inside to measure the change in pressure as the the volume changes.
In this experiment, students will:
1. Determine the relationship between air pressure and volume using a syringe.
2. Explore what is happening to the air molecules when there is a greater or less air pressure.
