Given that science and engineering practices are a large focus in the Next Generation Science Standards, biology teachers need to find ways to incorporate the engineering design process into their curriculum. To address this need, I present a lesson that allows for student collaboration in designing and developing a solution to a global problem resulting from overfishing and our use of unsustainable fishing practices. This lesson also demonstrates to students that larger, global issues that seem insurmountable to solve can be broken down into smaller, more manageable pieces. My approach involves having students research a problem related to sustainable fishing practices and design a physical model of a solution to combat their specific issue. Peer review is then used in order to help students revise and edit their models during the lesson in response to the peer feedback received. The lesson will culminate in a presentation to the class about the biological, social, and economic ramifications of both their assigned problem and a potential solution.
