This lab is not inquiry-based because the teacher must explain how to calculate pressure before doing the activity, but the lab gives students a great concept of what PSI means. They usually have no idea if 10 PSI is a lot or a little. They also don’t understand how a small pressure over a large area can create a large force. This lab helps them understand those concepts. There are great demonstrations to show the incredible lifting power of small pressures over large areas. Blowing up a trash bag with straws to lift a student is an example.
