Biology or ecology learners studying parasitism or food webs will learn a lot from this instructional activity on the activity of nematodes. Learners collect soil samples, bait them with insect larvae, and then examine insect carcasses over time to observe the parasitic action of nematodes. This activity is an in-class field study requiring minimal preparation and equipment. You get a lot of bang for your buck with this instructional activity!
