Curated OER
Water Pressure - Observing Water Flow
Pupils discover that pressure increases the deeper the ocean becomes. They determine how water pressure differs at various depths by observing water flow.
Curated OER
Math Under Pressure
Students are told that an air tank contains a fixed volume of air under pressure. As air is used, the pressure decreases at a rate that depends on the depth. Students discuss how SCUBA divers calculate the amount of time they can spend...
Curated OER
Divers's Decompression
Students are exposed to the physics and physiology of scuba diving, study the principals applied in the U.S. Navy Decompression tables and work out typical decompression problems.
