Earthworms are our Friends!
Our kindergarten classes are learning about earthworms. Here are some of the things we've learned:
They can live up to 10 years
They have no eyes, arms, legs or ears
They never sleep
They never catch diseases
They are able to eat their own body weight every day
They have strong mouth muscles but no teeth
They eat leaves and turn them into nutrients
They breathe through their skin
They can live underwater for a while
They are cold blooded
There are 2,700 different types in the world
They are perfect recyclers
They aerate and mix up our soil
They are extremely sensitive to environmental pollutants
They are very important for our soil!
After we watch them eat leaves & burrow into the sand in these jars for a few weeks, we will release them into the garden. We are experiencing more and more earthworms in the garden...a sign of healthy soil!
