Float Your Boat! – Scientific Method Project

CHALLENGE: Make a boat that can float in water and hold the most amount of pennies.

PROBLEM: The limited recourses each group has to make a boat in ten minutes.

HYPOTHESIS:  (Use an “If…then… because ”statement)

If the weight distribution is supporting the surface area of the boat, then the boat will hold many pennies because of the strength in balance the boat has.

IDEA FOR ORIGINAL DESIGN:  Insert image and write a description explaining your thinking/reasoning as to why you chose that particular design.

We as a group chose this design because we wanted the maximum balance on our boat so we made a tic tac formation as the base and put aluminum foil on top. Our intention was to make a dent in the middle of the boat and around the boat we make the coins fall off, to stop misbalancing. We also trapped the air in the straws by plugging the straws in marshmallows. This would theoretically prevent drowning if the straws absorb the water and provide an extra cushion. We put the remaining part of the marshmallow in the middle to have middleweight. Our main goal was to prevent tipping.

HOW MANY PENNIES DID YOUR BOAT HOLD?

The boat held 16 pennies.

WHAT WOULD YOU KEEP OR CHANGE ON YOUR BOAT DESIGN IF YOU WERE TO DO THIS AGAIN?

I would change the boat design because ours was ineffective; it was too small to hold many pennies. I would change the size of the boat to be larger, I would also make it deeper rather than a flat raft. The balance was very good (for its size). If I were to think of real boat designs, you don’t see many rafts holding more than two people, so it was a bad idea to create a raft design.
