Worm farm

For discovery block on Tuesday we are doing a worm farm. All we need is 3 buckets a tap and a lid. There will be holes at the bottom of the top and middle buckets. The middle bucket is to keep the soil and the worms. The top bucket is where we will put the scraps then the worms will crawl up the holes to eat them. The bottom bucket is where the worm wee will drain into. The worm wee will be drained out of the tap into a cup and used as fertilizer.
