Abstract	The author and his first-year algebra students explored the quadratic behavior behind the parabolic shape of fountains at the local family splash park. This hands-on 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).
