Teachers, save “(A2.7) Engineering Design Process: Fresh…” to assign it to your class.

Engineers use science knowledge to design solutions to solve problems. The city of East Ferris has a water shortage problem. Mayor McKnight has learned that it is possible to get freshwater from salt water. Distilling is the process of purifying a liquid by vaporizing, cooling, condensing, and collecting it. Mayor McKnight wants you to work in collaborative groups to design and build a freshwater collection system. A system is a group of parts that work together. Design Problem: Convert salt water into freshwater. 1. Observe the materials. 2. With your group, discuss a plan for your freshwater collection system. 3. Design Plan: Draw a diagram of what your freshwater collection system will look like. Label the parts. Take a photo of your plan. 4. Think: How will your freshwater collection system allow water to condense? 5. Build: Build your Freshwater Collection System. Take a photo of your system. 6. Test: Add saltwater to test your system. Take a photo. 7. Go to Seesaw and open Freshwater Collection System (A2.7). 8. Document: o Take a photo of your plan and upload to slide 1. Use the microphone to explain the challenge and identify your design plan. o Take a photo of your Freshwater Collection System and upload to slide 2. Use the Seesaw Tools to Label your system. Use the microphone to record a summary of how you hope your system will work. o Take a photo of the saltwater in your system. Label your initial observations. Use the microphone to record a summary. Include the date and any immediate observations. 9. Save as a draft. 10. Wait for results.
