Boat or Submarine  

Question/Goal/ problem

make a shape that will hold more than 11 coins

What shape of container will hold the most weight ?

We are choosing a pan because it is wide and the wider it is, the more water keeps it afloat

Hypothesis

• It will be able to hold more than 5 coins.
• 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

We made a pan and we got 5 coins in so that's pretty good we thought we needed the pan to be bigger.

Conclusion  

I discovered that if you make it light the water support’s it more.

It floated because it was light

"Ok class What happens when I do this?"
