Some kids may squirm when they see an earthworm, but for most kindergarteners, these slinky critters are rather fascinating. And for budding scientists, earthworms also an important part of the study of earth science and conservation. Healthy soil should contain lots and lots of worms—they break down raw materials like dead leaves, ventilate the soil as they move through it, and build it up with their casings.
There’s only one problem for avid year one scientists: worms do all this underground, in the dark!
