Composting is a great way to get children involved in recycling. First, they discuss how biodegradable products decompose to make compost. Then, they talk about what can and cannot be composted. They play a game similar to around the world where they toss a ball to each other, calling out compostable materials. Once everybody is sitting down, they play a game of tag that continues to reinforce the concept of composting biodegradable objects.
