What is buoyancy?
Criteria: Boat must be made of one 5x6 piece of foil
- You can only use foil
- When testing the boats, the last mass added to the boat (the one that makes it sink) must be removed from the boat before totaling the mass that the boat held.
Check out this episode of "Ruff" on building a better flotation device. How is a billion dollar boat made? Check it out here.Brainstorm ideas. Choose the best one.
PLAN: Check out a few of our diagrams here.
CREATE: It was fun to test out our foil boats. We found that our boats shaped like rafts fit more pennies, than boats shaped like canoes. We also found out it was important for us to put pennies in all parts of our boats. If we put all the pennies in one spot it would sink fast. Some of our predictions were WAY too low and others too high. Noone had a prediction that was the same as th outcome. The winning boat held 72 pennies!
IMPROVE: Reflections coming soon!
