Cooking with quadratics. (English)
Math. Teach. (Reston) 104, No. 4, 308-314 (2010).
Summary: A project that mixes algebra with data collection, uses technology, extends into data analysis, and cooks marshmallows can excite both teachers and students. This article describes a project that intends to pique students’ interest in higher mathematics, incorporate their knowledge of parabolas, and offer a meaningful mathematics experience. Using basic properties of a parabola, students collect and analyze temperature data and construct a three-dimensional model from a quadratic equation‒to cook marshmallows. Cooking with quadratics made mathematics meaningful to students. A student instruction sheet and project guidelines are included. (Contains 3 figures and 2 tables.) (ERIC)
