In this unit I plan to explore electronic inventions that are directly related to the evolving of Technology At Home throughout the 20th century. I will look at household gadgets that use electricity, that students feel that they can't live without, such as: the telephone, refrigerator, television, stove, microwave, stereo, tape recorder, radio, vacuum cleaner, washer and dryer.
All of these products exist because of the discovery of electricity. Exploring the basic fundamentals of electricity, I plan to give middle school students a good understanding of how electricity works. We will examine life before electricity. List some possible motivation that pushed for its discovery. Once discovered, what people made electric inventions that led to the contributions that enhanced people living condition and their continued improvement through technology?
