My school hosted a sustainbility fair which had many interesting displays and booths all about sustainibility. My Favorite part about the sustainbility fair was the worm bucket. It was so intereting because when the volunteer lifted the first bucket you saw decomposing foods and alot of worms eating it. When she lifted the next bucket underneath there was some soil and some decomposed foods and a different type of worms eating it. IN the last layer there was just soil which was made from the composte pile earlier. It was so intersting how a composte pile can turn into perfectly good soil. AMAZING!
