Technology Lessons is part of a University of Michigan Web site operated by Reach Out! and the Southeastern Michigan Math-Science Learning Coalition. There are many lessons that have been divided into appropriate age levels, ranging from early elementary school to high school. Each lesson begins by discussing insights and connections into the subject and is followed by a main activity with suggestions for extending the concept further. Topics covered on the site include Electric Cars, Making a Steam Powered "Rocket Boat," and How TV Works, to name just a few. The lessons are all interesting and educational, and can be used in or out of the classroom.
