Boats and STEM

This week my students have been working on a STEM boat project. We had been talking about absorbency. The goal of this project was the students would design, build, and test a boat. They had several opportunities during the week to make changes. The only catch was they were given so much money to spend, as when they were broke. That was it. Some of the boats turned out really amazing, and they held a lot of weight. Then some boats sank immediately.
