You've got to pump it up! Using the equations for projectile motion and Bernoulli's Principle, class members calculate the water pressure in a water gun. The pupils collect data on the number of pumps and distance traveled in order to determine values used in the equations. They then create and analyze graphs to determine the relationship between the pressure, the number of pumps, and the distance the water travels.
