Making compost is not only a great way to recycle your leftovers and provide yourself with rich organic material for your garden, but it's also a great way to teach children about how things break down into the earth.
Steps to be taken
1. Purchase a compost bin, or let making a bin be part of the project.
2. Fill the bin with dried leaves, grass clippings, vegetable peels, newspaper and other materials that break down easily. You can observe over time how things break down.
