Decomposer Dynamics

Students propose how dead plants disappear over time, then examine mold, and talk about microbes as decomposers.

Students hear a story of a scientist who studies microbe decomposers, then plan and take a trip outside to collect items for culturing microbes.

Students do a controlled experiment to culture microbes living on items they collected outside.

Students work in groups to create displays that show what happens to a dead leaf over time.

Students test factors that promote the growth of microbes, then use their findings to make compost.

Students design and set up model waste disposal systems that will help biodegradable plastic bags decompose

Students analyze a trial involving a dispute about a composting business, then outline how a Special Investigator could gather evidence to help settle the case.
