We got a 30 cm x 30 cm foot of aluminum foil and tried to make a rectangular boat that will hold the most plastic bears. The point of this is to see what ratio of height to width to length will be the best at holding plastic bears.
Prediction: My prediction is that the sides should be an inch tall and that it should be 3/4 as wide as it is long. I think it will hold about 40 bears.
Assumptions:
- Everyone uses a 30 x 30 x 30 cm piece of foil
- All sides must be square (rectangular)
- Only use big bears
Boat Dimensions:
height = 5 cm
length = 22 cm
width = 22 cm
volume = 2420 cm3
Based on Emma's, I'm changing my prediction to 150.
Results: It held 209 bears and 25 spoons.
Experiment #2 (try 2)
We're not going to use bears anymore, because they're too light. We're going to rebuild our boats and only use spoons.
Boat #2 Dimensions:
length = 17 cm
width = 17 cm
height = 7 cm
volume = 2023 cm3
I made the sides higher because the last one sank because the water went over the sides.
Prediction: I predict it will hold 60 spoons.
"We've used ALL the bear counters. What do we do now?"
