World Food Day / Regrow Kitchen Scraps

Regrow Kitchen Scraps

Children rescue vegetable scraps like spring onion roots and celery bases, set them in water and watch new growth over the following days.

How to run it

  1. Talk about how much food gets thrown away and how scraps can still be useful.
  2. Give each child a scrap such as a spring onion root end, celery base or lettuce stump.
  3. Stand each scrap in a shallow cup of water on a sunny windowsill.
  4. Children draw and measure their scrap each day and change the water every second day.
  5. Plant the strongest regrowers in the garden or pots after a week.
