Iteration: Redesign
As this poster from Ms. Salchli's classroom illustrates, framing failure as a learning opportunity motivates students to think about how they could make their designs better, rather than focusing on their design not working.
Reflect on the redesign step in the second water filter video on page 15. Recall how Ms. Salchli discussed the implications of doing only one cycle of design and building. Watch the video again if you'd like, then answer the following questions:
- What are the advantages of the iterative process?
- How do you currently use iteration in your classroom? Maybe you use it in ELA or math rather than science. How could you incorporate techniques you already use to help motivate your students through the engineering design process?
