This Earth Day, why not make a compost bin? Put some soil in a plastic bin or tub. Add leaves and twigs. Moisten with water. Now you can add scraps of fruits and vegetables. You can also add coffee grounds and old tea bags.
How does composting work? Tiny creatures found in soil will feast on the food scraps. They will break them down. The soil will become rich with nutrients. It can be used to grow plants.
Look at the illustration below. It shows which items should be composted and which should not. Use it to help you with your compost project.
