The invention of the typewriter led to the keyboards on the computers of today. Show your class a computer and a typewriter or two if you can find significantly different typewriters, such as a manual one and an electric one. Begin an inquiry-based study that compares typewriters to computers. Students can talk about everything from the appearance of the two tools to the way that one gets the final, finished product (a piece of paper with alphanumeric figures on it) to the different ways that they might use the two machines if they were composing a paper. As a conclusion to the project, ask students to hypothesize about how the shift from typewriters to computers changes the way that work is done.
