Pressure

In this topic, you will learn about density and pressure. Density and pressure are very important to divers. Water is eight hundred times as dense as air and this has a dramatic effect on pressures felt by the diver. In this topic, you will learn the physics behind  the changes in pressure in fluids and why this is important to divers. You will calculate the pressures at different depths in water.

Essential Questions:

• What is density and how is it measured? 
• What is pressure and how is it measured and calculated?
• How does pressure change as you go deeper underwater?
