Composting

This Composting lesson plan also includes:

Using 2-liter bottles, junior ecologists create composting tubes in which they place nitrogen-rich and carbon-rich materials. They observe what changes occur over two weeks' time. Provide more specific direction to your class as to what observations should be made: Does the total mass of the tube and its contents change? Does the color or volume of the materials change? How can the drainage that is produced be described?
