This page is the worksheet’s home: see the whole sheet, download it or print it, and pass it on. Solving on screen happens in the class’s own activities on the Learning Path — this page is for the table, the kitchen and the fridge door.

Six object cards — a wooden cube, a metal spoon, a cork, a stone, a toy boat and a metal key — above a water tub with a FLOAT bin and a SINK bin.
ABOUT THIS WORKSHEET

What your child practices.

Sink-or-float is the classic first experiment because the prediction feels brave and the test is instant. The material is the hidden clue — wood and cork trap air, metal and stone do not — and the bath confirms everything.

  • Making predictions
  • Sorting by behaviour
  • Material vocabulary (wood, metal, stone, cork)
  • Testing ideas

On the sheet: Guess which objects will sink or float!
