Cool Puppy! A Doghouse Design Project

Students are given the engineering challenge to design and build doghouses that shelter a (toy) puppy from the heat—and to create them within material, size and cost constraints. This requires them to apply what they know (or research) about light energy and how it does (or does not) travel through various materials, as well as how a material’s color affects its light absorption and reflection properties. They work through the engineering design process as they build their doghouse designs and test them by taking thermometer readings under hot lamps, and then think of ways to improve their designs. This is a great project for learning about light and heat: energy transfer, absorption, insulation and material properties, and easily scales up/down for size and materials.
