Earthworm Soil Test

The Abundant Garden: Growing Quality Kids Through Gardening by Kinderfarmhomeschool.comImage by WordSwag

Earthworm Soil Test – an activity for children of all ages. We can read all the books in the world about how important earthworms are to soil, but until we see it with our very own eyes, we may not really understand or believe it. This experiment will allow a child to see for themselves the impact worms have on soil. Do they truly make a soil richer?

*Note: this experiment was adapted from an activity found in the Wiggling Worms at Work book by Wendy Pfeffer.

  • Supplies:
    • two medium-sized pots
    • gardening gloves
    • spade
    • soil
    • worm castings (you can find these on Amazon, in your worm tower or in the soil outdoors)
    • seeds of your choice: we suggest pumpkin seeds or alfalfa (if you live in a colder climate, you may need to move your pots indoors)
    • gardening notebook/journal
    • paper (if using a binder) – copy paper, cardstock and/or 140 lb weight paper if using watercolors
    • pencil and eraser
    • art medium of choice (colored pencils, watercolors, crayons, or markers)
    • page protectors
  • Fill both pots with soil.
  • Add the worm castings to one pot.
  • Plant seeds in each pot per seed packet’s directions.
  • Place both pots in the sun.
  • Water the plants equally, again per seed packet’s directions.
  • Note and document findings.
  • Place the page(s) in a protector when finished and include them in the garden notebook/journal.
  • Don’t forget to transplant your plants outdoors when able (will depend upon your growing zone).
  • Take pictures and tag #theabundantgarden on Instagram to share your fun and for an opportunity to be featured @theabundantgarden.
