Lesson focuses on how technology and engineering impact society, and how poll-taking has been influenced by engineering over time. Students design and construct a voting or polling machine out of everyday items, then evaluate the effectiveness of the design.
As a result of this activity, students should develop an understanding of:
mechanical engineering and design
voting and polling systems
Students learn how methods of voting have adapted over time using engineering to increase accuracy and privacy in voicing an opinion. Students work in teams to develop a voting system using everyday items. Teams plan their mechanical system, execute construction, troubleshoot, evaluate their own systems and that of other students, and present their findings to the class.
