Students could have class demonstrations showing the decomposition of leaves through biodegradable, incineration, creation of gas through biomass. Students will decide which are more efficient processes of disintegration. Have students make a diagram of the life and death of a tree and what it goes through to show some natural stages of decomposing. Then have students make a diagram of the life and death of a wood product like a chair. Conclude with statements about man's role in utilizing resources.
Solid waste is disposed in a variety of ways.
Some are natural processes, but some may require awareness as to their impact upon other living organisms. Parents can show how much of their taxes are spent on a landfill. They should be prepared to answer what they are putting in that landfill. Students will correctly define and spell vocabulary. Research what things take up the most time to decompose.
