Summary: The author and his firstyear algebra students explored the quadratic behavior behind the parabolic shape of fountains at the local family splash park. This handson discovery project has three main parts: (1) gathering data by experimenting with and photographing the fountains; (2) analyzing the photographs to obtain numerical data; and (3) creating and fitting appropriate quadratic equations to the data. This experience could easily serve as a capstone project for a unit on quadratic equations. (Contains 8 figures and 1 table.) (ERIC)
