Compost Heater

Compost Bioreactor Design

Grades:
7-12
Unit:
Bioreactor Water Heating
Lesson Number:
2
Description:

Solar energy is available when the sun shines but energy can be supplemented at night by the release of energy during the composting of organic waste. In this activity, we will experiment with the feasibility of harnessing thermal energy to heat water with...

Learning Goal(s):
1. Students will research the science of composting and proper maintenance methods to build their own bioreactor. 2. Students will research the proper composition of compost for maximum heat production. 3. Students will transfer the thermal energy in compost to a container of water heat water with by placing a vessel in the middle of the active compost/bioreactor.

Learning Goal(s):
1. Students will examine the properties of solar water pumping systems using KidWind solar water pumps or similar water pumps. 2. Students will experiment with the properties of water and its limitations in circulating due to pump power and distance. 3. Students will evaluate the use of a heat sink/chiller in the circulation of water through the bioreactor.
