Boat or Submarine
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
ConclusionI think the wider the better and the thinner the better.
