In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design. Learners read about several different valves used at home and in industry, and three different mechanical heart valve designs. Learners then examine and operate both a ball valve and a gate valve. Finally, learners work as a team of "engineers" to develop and sketch enhancements to the mechanical heart valve.
