A couple of weeks ago we created a small compost bin for a science project. Everything I had read since putting it together informed me that regular earthworms out of your yard would not work in breaking down the garbage. Guess what? They sure did. Just about every piece of veggie material was eaten and turned in to soil. Grace was so excited to see what the earthworms had actually done. I took the photo of the earthworm to show you just how big they had become. Originally about three dozen earthworms were placed in the bin and they were probably 1/4 the size they are now. Great experiment. Grace loved it.
