Boat Or Submarine

Title  Boat or Submarine  
Scientists: Inderpreet and Zeb.

Question/Goal/ problem
What shape of container will hold the most weight ?
My partner and I have decided to go with pan.

Hypothesis (The shape I have chosen and why I think it is the best shape)
Because it has a larger bottom, it can hold more coins and can float.

Container filled with water, modelling clay, old coins

Method (What I did)
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)
It sunk because it got heavier and holes were formed.

Conclusion  (What I discovered about floating/ sinking )
The bigger it is the better it floats and it can hold more coins.

This is me and Zeb's container, it successfully held 5 coins!
Oh yeah, this is a pan alright...
