Description:

Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes. They place carrots in plastic bags filled with soil (with or without added materials), then subject these bags to different conditions. Every few days, students 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.
