Consumer electronics: A high school unit on solid state physics

The Consumer Electronics unit developed during this study is a series of labs and lessons designed as an extension of a regular introductory Physics unit on electricity. It is intended to achieve four broad objectives: (1) To help students maintain a childlike enthusiasm for science. (2) To provide students practical experience using and extending theories learned in previous lessons. (3) To develop the idea that real-life situations often require a deeper understanding of physical interactions. (4) To help students gain the determination and skills required to handle complex problems.; The centerpiece and inspiration for this unit is the construction of a working oven from a tissue box lined with aluminum foil. Developing an understanding of the science principles involved as well as the actual building of the oven comprise the first three weeks. The second half of the unit is an exploration of the physics behind the electrical devices that define our modern world. Based on personal observation and testing of core concepts, I found the teaching of this unit to be successful both in terms of student enthusiasm and involvement.
