Make a Worm Compost Bin

Worms might make you squirm, but many kids love them. Harness this interest with a worm composting project, suggests Kristin Arrigo, environmental writer and author of Seasonal Home Repair Checklist: Eco-Alternatives for Maintaining Your Home. Use a shallow plastic box with a loose-fitting lid. Drill a few drainage holes in the bottom of the box and place a tray underneath. Lay torn newspaper or cardboard in the bottom of the box and mist it well for worm bedding. Add a half-pound of red worms. Each week, add up to 3 pounds of kitchen scraps, such as vegetable and fruit peels, coffee grounds, egg shells and stale bread. Place more newspaper over the scraps and mist well. In six months, you’ll have rich, dark humus for your garden!
