Sinking and floating is great first science activity for even very young children and can easily be extended for older children. We’re all about the pirates this week, so collected lots of pirate themed treasure to test.
A large container half filled with water
Pirate treasure – coins, necklaces, bracelets etc
Somewhere to record your results
Plasticine – to extend the task
Ask the children to feel each object and predict whether they will sink or float.
Record the predictions in a table ( printable coming soon )
Test each item by dropping it carefully into the water.
Record your results.
Can you make a plasticine shaped boat, what happens if you place an object that sank into the boat?
