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.

Materials

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.

The stuff Inderpreet and I made our boat out of.
