What you need

A shallow unbreakable bowl, a little water, a large clean sponge, and a large metal spoon.

Age: 3–5 years; choose for the individual child.

Let's make it happen

  1. Adult places a little water in the bowl and shows the sponge and spoon.
  2. Guess which object will stay at the surface, then adult gently places each in the water.
  3. Observe which floats and which sinks, then talk about whether the results matched your guesses.

Adult handles the objects and shallow water, stays within arm’s reach, and empties the bowl and dries spills afterward.
