Boat or Submarine
Scientists:
Question/Goal/ problem
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.
Materials
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
Conclusion
I think the wider the better and the thinner the better. .JPG) |
