Float Your Boat challenge – scientific method project

CHALLENGE:

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

 

PROBLEM:

to build a boat that will hold the most number of pennies while staying afloat

 

HYPOTHESIS:

if the weight is distributed evenly onto the boat then the ability of holding the most amount of pennies would improve because all sides would be constructed parallel to each other and evenly balanced; eradicating any chance of tipping to one side.

IDEA FOR ORIGINAL DESIGN:

We believed that even weight distribution was key in our construction, so we attempted to make our construction as symmetrical as possible. For example, we made sure that all the straws were cut at all the same length and placed 4 marshmallows; one on each side of the boat to create even buoyancy all around. Our original inspiration was how a boat / raft was constructed. Using the boat’s football-like shape, we added a canoe inspired inside beaming on the inside to prevent the bottom from collapsing on itself and mimicked a raft’s side beams on the bottom for flotation. We also used marshmallows to act as buoys.

 

HOW MANY PENNIES DID YOUR BOAT HOLD?

Our boat was able to hold 98 pennies, just short of 100.

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

I believe our boat construction was very successful; there is not much i would change except for maybe reinforcing our walls. Rewatching the video, I noticed that the boat floor and buoyancy worked well, but the reason why our boat sank was because of a wall collapsing in on itself. If given the opportunity to redo this challenge, I would have sacrificed a bit of the boat’s size to give extra reinforcement to the sides of the boat by folding it in on itself to make it thicker and sturdier.
