Students taking Calculus Honors designed and printed their own 3D objects in the Phyllis M. Taylor Maker Lab. Working together in small groups, they calculated the volume of their object through measurements. They filled their objects with water and filmed the water pouring out to determine the rate that the object was losing water. They performed this test three times. They then measured the true volume and created a free response question to have other students in the class calculate at what rate the height of the object was losing water at a specific time. This is known as related rates in calculus.
