Energy From Garbage

Source: The Need Project
Topics: Preteen Years (9-13), Great Science Fair Project Ideas

Grade Levels:
4-6

Questions:
Can you produce a gas from decaying garbage?
Can you control the amount of gas produced from decaying garbage?

Possible Hypotheses:
A gas is/is not produced when garbage decays.
The amount of gas from decaying garbage can/can not be controlled.

Materials:
Packet of dried peas or beans
Six airtight clear plastic bags
Water

Procedure:

  1. Soak the beans or peas in water overnight.
  2. Place 10 beans or peas into each bag and squeeze out all the air before you seal them.
  3. Put two bags in a warm sunny place, two bags in a warm shady place, and two bags in a totally dark place for a week and observe what happens. Record your observations.

Analysis and Conclusion:
Did the decaying beans produce a gas? Which environment was best for producing gas? Do you think the gas could be used as a source of energy? Why and how?
