Environmental Factors and Decomposition


The purpose of this project is to determine what environmental factors favor decomposition by soil microbes. They will use chunks of carrot for the materials to be decomposed, and their experiments will be carried out in plastic bags filled with dirt. Every few days the students will remove the carrots from the dirt and weigh them. Depending on the experimental conditions, after a few weeks most of the carrots will have decomposed completely..
