Fifth grade is finishing up a project in which they were given the task of designing and building an iPhone dock for me made out of Legos. Most of the students had used Legos before to create models, such as cars and airplanes, but none had built an item out of the material that actually could be used for something useful. The students were given my criteria in the first session and then began building. In the second session, they attempted to improve their design. Students in lower grades were able to view the prototypes and evaluate them.
