Old banana peels, apple cores, and moldy bread: doesn't sound very appetizing for people, but for worms, it's a feast fit for a king. Trevor Roy explains:

"It was fun, and they're wiggly and they were cute and they were tiny"
Seven year old Shelby was just one of the kids feeding worms at UMD's child place day care center.

The kids were learning about the benefits of composting.
Composting is a way to make fertilizer that can be used in gardens and help the environment at the same time.

Here's how it works; wasted food products like orange or banana peels are put in a large bin filled with soil and worms.

The worms eat the peels and transform the waste into a useable fertilizer.

Day care director Jen Johnson says this is a way for the kids to learn about protecting the environment.

"Teaching the children the importance of taking care of our world and our environment, especially now–a–days. You know the big concern is our globe, our global environment and how we're treating it and you know so now's the time to teach them that"

Just don't ask her what kind of worms they are.

"Red...wiggly, I think it's something like that. "

The worms will be on the job permanently at the day care, eating and recycling the kids scrap food from their meals and snacks.
