Building challenges- boat builders

The blue group continue to explore modes of transportation. This week, we explored some ideas about boats and floating. We initially challenged the students to build a boat that would hold a marble. We set out a variety of materials such as pipe cleaners, plastercine, wooden popsicle sticks, lego, etc. We had limited success. 

We then watched a few videos that helped explain why boats float and how to build a tinfoil boat.

After watching the video, many students asked to use tinfoil, and formed them into a canoe shape. 

We were able to make boats that held many marbles.
