In the Waterproof That Roof! challenge, students had the opportunity to take on the role of a structural engineer. We talked about the relevance of this challenge with the increase in more extreme weather events like Hurricane Sandy, and the importance of having safe and secure structures. We also did some research on roofs and how they are constructed. We learned about the pitch or angle of a roof, gutter systems, and the difference between absorbent and repellent materials.
Part of the challenge involved taking on the real challenges an engineer faces and having to work within constraints or limits. In this challenge, students had to work in material, budget, and time constraints. They followed the steps of the Engineering Design Process to complete their work.
The Challenge: Waterproof That Roof!
You are a team of engineers given the challenge of creating a waterproof roof for a small house. You may use any of the materials available to you, however you need to stay within the given budget. Your team will need to devise a frame and covering that will prevent water from entering the interior. You can expect a rainstorm containing a liter of water!
