Dry beans pressed against the glass by damp paper open up over a week: first a root, then a stem, all of it in plain view. Your child measures the sprout every morning.

What you need

  • Clean glass jar
  • Paper towel or cotton wool
  • Dry beans or peas
  • Water
  • Ruler or a strip of paper

How to play

  1. Line the inside of the jar with damp paper towel.
  2. Slide three beans between the glass and the paper so they stay visible.
  3. Pour a little water into the bottom so the paper never dries out.
  4. Stand the jar on a warm windowsill and keep the paper damp every day.
  5. Measure the root and the stem each morning and mark them on the paper strip.
