Models in Technology and Science by Bernie Zubrowski. Students carry out simple tests of different kinds of containers to determine what is the best kind for making ice cream. They then gather data on cooling rates of hot water in a selected container surrounded by three different cooling solutions. A cardboard box oven is constructed to study convection and radiation. Collected results are used to make ice cream in a container and bake a cake in the cardboard box oven. These experiences provide the context for introducing conduction, convection, radiation, and phase change.
