Answer:
Decomposition occurs everywhere. If everything existed forever, we would be buried in our waste. Our waste products are varied: some are made of easily degradable materials while others will last for thousands of years.

Display a piece of glass, paper, metal, plastic, and food. Ask the class to predict which of these substances are biodegradable (capable of rotting or decomposing)? Conduct the following experiment to determine whether their predictions were correct.
Dig enough soil from a garden or vacant lot to fill five containers. (One pound cottage cheese containers would be suitable.) Fill five of the containers half fullwith soil, and the other five half full with sterile potting mix. Place a piece of each type of waste into each container. Continue filling the containers with soil or sterile mix, whichever they already contain. Add enough water to all pots so that the soil or sterile mix is damp but not wet to the touch. Cover the containers. Label the containers to indicate the type of waste and whether it contains soil or sterile mix.
After one week, examine the waste in each container. Which wastes are decomposing? Cover the wastes again, and continue to check them once a week for as long as you want. Record your observations.
Check the original predictions and draw conclusions about which substances are biodegradable and under what conditions.
