Electrical Inventions Timeline

Students are looking at a variety of inventions created that use electricity.  Using a timeline, where they ordered the given times themselves, students started looking at ordering different electrical inventions by date.  They were encouraged to use critical thinking skills (ie if a microwave uses light then the light would be invented prior to the microwave) to help them decide where to order items, and it was great to see schema coming into play as well (some students asked when Thomas Edison was born to help them decide when his invention would've been invented).
