Anyone who dives under the surface of the water notices that the pressure on his eardrums at a depth of even a few feet is noticeably greater than atmospheric pressure. Careful measurements show that the pressure of a liquid is directly proportional to the depth, and for a given depth the liquid exerts the same pressure in all directions.the pressure at different levels in the tank varies and this causes the fluid to leave the tank at varying velocities. Pressure was defined to be force per unit area. In the case of this tank, the force is due to the weight of the water above the point where the pressure is being determined. You may have noticed when you swim underwater, that the deeper you go the greater the pressure on your ears. You ve also probably seen how deep-sea divers must protect themselves against the water pressure at greater depths. This may get you curious as to how to verify the relationship between water pressure and depth.

Finding the relationship between water pressure and depth can be an idea for a science project in the area of physical science. The biggest problem is in measuring water pressure. A clever way to demonstrate increasing water pressure is by showing how far it will squirt from an opening.

Questions you may have include:

What is the purpose of the experiment?
What research must be done?
What is the experiment?

This lesson will answer those questions.
