LIFE VEST CHALLENGE PRESENTATIONS Slide 6 should include: • Thoughts from your team reflections • What things went well during challenge • Struggles and how your faced them • Changes you would make next time 18
Cardboard Chair Challenge Our team really struggles during the design phase. We had a hard time converting our measurements to 1/10 th scale. WE also struggled to build our scale model. Upon reflection, we found that these struggles made our construction phase go much smoother. We had worked out many problems we would have faced during the design phase. After reflecting, our team would make the following changes to our design: • Make base 1. 5 feet tall instead of 2 feet tall. • Provide more support in the back piece. 19
