Students complete this lab and show their knowledge of thermodynamics, heat transfer, insulation, and conductors. Students, over the course of a week, will draw and design a device that helps to stop the transfer of heat. They will begin the lab by brainstorming ideas for a design. They will also have an explanation sheet that says why they chose to use certain materials. Included in this lab are student directions, a student checklist, a grading rubric, and an explanation of each part of the lab that students must turn in. You can either supply the students with materials in order to create their cooler, or you can allow them to bring their own things in. In the past I've given out prizes for the most efficient cooler and also the overall best cooler. Students love the competition part of this lab and generally it is one of my most engaging projects of the year.
