MessA little messy

You need

  • Ice cubes
  • Two small plates
  • A sunny spot and a shady spot

Let's play

  1. Put one ice cube on each plate.
  2. Set one plate in the sun and one in the shade.
  3. Guess which will melt first.
  4. Check every 5 minutes. Which melted faster? Why?
Grown-up tip: Try a third cube under an umbrella you build: can you slow down the sun?
