ab: Summary: 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)
