Science: Race a Speedboat

Water tension Experiment
Equipment:
  • Coloured card
  • Washing up liquid
  • Pencil or sharpie
  • Scissors
  • Large container of water.


Prediction:
I think the boat will stay in-tact because the dishwasher liquid might be like a boost so it reaches the other end and then the boat might sink at the end.


Observe:
When I placed my boat into the water and placed my finger in there with the liquid, it glided.


Explanation:
I think it happened because paper is really light.


Metal clip Experiment
Equipment
  • Large container of water.
  • Metal paperclip.


Prediction:
Because it is made out of metal, it will sink.


Observe:
After a few tries, the metal clip finally floated.


Explanation:

It floated because if you gently place it down, the water’s surface won’t break causing the metal clip to float.
