Boat or Submarine

 Boat or Submarine  

Question/Goal/ problem
What shape of container will hold the most weight ?

Hypothesis ** Our shape is like a long rectangle and we think it will be good because it is quite wide because it will carry more coins.

Container filled with water, modelling clay, old coins

Method Create a boat out of modelling clay.
I Fill the container with water.
Place the boat carefully onto the water so it floats.
One at a time , put coins carefully into the boat . Count how many coins are in the boat before it sinks.
Observation/ Analyse (What happened and why I think it happened)
**Our shape held 6 coins  but then it sunk because it wasn't big enough and it was a bit too thick and it was to heavy

I think the wider the better and the thinner the better.
The pefect boat (Just about.)
