Explore the physical concepts involved when humans dive in the ocean. See how physical factors change as divers move deeper underwater. Learn how SCUBA allows us to discover an underwater world. Students will witness the changes in light underwater and the relationship between pressure, density and volume.

Physics of Diving Bottle Demonstration
What happens to pressure as depth increases? How does this affect the volume of an air filled space? See what happens and measure the volume of air in a two-litre bottle as it is brought up from the ocean depths by scuba divers during a Physics of Diving Live Dive.
