Under Pressure

Source: Teach Engineering

Description: Students learn about Pascal's law, an important concept behind the engineering of dam and lock systems. Students observe the behavior of water in plastic water bottles spilling through holes punctured at different heights, seeing the distance water spurts from the holes, learning how water at a given depth exerts equal pressure in all directions, and how water at increasing depths is under increasing pressure.

Topics explored: hydropower basics; hydrology; dam materials; dam types; water pressure
