Botanical Leaf Chlorophyll Steam Extraction Print

35 mins Ages 7-9 Indoor

An engaging, screen-free learning activity that builds real-world creativity and critical thinking for kids aged 7 to 9.

Materials Needed

  • • Fresh green leaves and colorful flower blossoms (4–6 leaves)
  • • White cotton fabric scrap or heavy watercolor paper (1 sheet/cloth)
  • • Smooth rounded river stone or wooden craft mallet (1 unit)
  • • Wooden cutting board (1 unit)

Pro Tips

  • → Hapa zome is the Japanese art of pounding fresh plants and flowers directly into cloth or paper.
  • → Sandwich fresh green leaves between two layers of paper towel or raw cotton fabric on a wooden cutting board.
  • → Tap the leaf firmly with a smooth stone: ruptured plant cells release chlorophyll dye, transferring an exact green leaf print.

Safety First

Watch fingers when tapping with smooth stones or wooden mallets.
