ab: 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 studentsâ€™ 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 equationâ€’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)
