I would like to share this engaging lesson idea from: http://sciencenetlinks.com/lessons/technology-past-present-and-future/

This lesson aims to broaden students’ awareness of technology by examining inventions of the past and present and by learning how inventions inspire and lead to the development of other inventions.

Students investigate through the focus questions by using the Wayback Machine website – http://web.archive.org/web/20080709054044/http://www.cbc.ca/kids/general/the-lab/history-of-invention/default.html

Students can learn more about inventors and inventions by exploring the Inventor of the Week Archives from The Invention Dimension. This extensive database offers an alphabetical listing of numerous inventors of the past and present and detailed information on their important accomplishments.
