Since I was just a child, I thought worms were fun. Maybe that was because my earliest memories about worms had to do with helping my aunt dig in layers of composting leaves to find fishing worms. What could be more fun for a preschooler than digging in mud to find cute, little wiggly critters? It is my theory that all young children love worms until that older sibling throws the worm on the unsuspecting younger child, who is then convinced the worm has something to do with the trauma. Otherwise, children seem more than eager to befriend any earthworm without reserve. But even though I grew up with a positive view of worms, I really had no idea what amazing creatures they really are, filling an invaluable role in our world.
