Get to know quadratics from a couple of different perspectives. Classmates work in small groups to determine the optimal cooking time for microwave popcorn. Group members pop bags of popcorn for different times and collect data on the number of good kernels. They determine the equation that models the graphed data and search for a picture of a parabola, overlaying a coordinate grid over it to find the equation in vertex form that fits the picture.
