Boat or Submarine

Title  Boat or Submarine  

Scientists:

Question/Goal/ problem

What shape of container will hold the most weight ?

Hypothesis We have chosen a bowl because it will hold more weight because it is bigger.

Materials

Container filled with water, modelling clay, old coins

Method (What I did)

Create a boat out of modelling clay.

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 We put the shape into the water and put coins on it and it sink. I think it happened is because it was bigger on the sides and it sunk.

Conclusion  (What I discovered about floating/ sinking )
