Soil: The Great Decomposer DLESE Reviewed Collection
http://www.globe.gov/tctg/decomp.pdf?sectionId=107
From GLOBE Program Collection
Comment on this resource
The purpose of this resource is to understand that soil, under different environmental conditions, plays a role in the decomposition of organic materials. Students use bottle experiments to observe changes in the decomposition of vegetable scraps. Students vary temperature, moisture, and light conditions to determine the conditions that best facilitate the decomposition of organic material in soil.
