I took a large pile of aluminum soda cans just waiting to be recycled. After talking (briefly) about recycling, we went outside with the cans. Oohh! It was cold! But the boys didn’t mind; they were busy running around and keeping their bodies warm with our activity. Each boy grabbed a can and stomped it flat. Then they grabbed a second and stomped it flat. Stomp! Stomp! Stomp! Soon we have a great pile of flat cans to put in our recycle bin.
