National Council of Teachers of Mathematics' (NCTM's) (2000) Connections Standard states that students should "recognize and use connections among mathematical ideas; understand how mathematical ideas interconnect ...; [and] recognize and apply mathematics in contexts outside of mathematics" (p. 354). This article presents an in-depth problem-solving activity that can enhance students' understanding of the connections between a function and its derivative and generate important connections between mathematics and physics. Using motion detectors, calculus, and physics, algebra and precalculus students create height-, velocity-, and acceleration-versus-time graphs of a bouncing ball. After constructing their own graphs, students can compare their solutions to those produced by the calculator. (Contains 12 figures.)
