This article describes an interdisciplinary unit of study on the inquiry process and experimental design that seamlessly integrates math, science, and reading using a rubber band cannon. This unit was conducted over an eight-day period in two sixth-grade classes (one math and one science with each class consisting of approximately 27 students and lasting 45 minutes). The authors begin by describing a series of interrelated curricular engagements that make up the unit. Throughout, they share samples of student work. Lastly, they describe some lessons learned and discuss both problems and pleasures of creating and implementing an interdisciplinary curriculum at the middle level. To get students started, the authors provided an overview of the interdisciplinary unit and displayed a rubber band cannon.
