Biology or ecology learners studying parasitism or food webs will learn a lot from this lesson 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 lesson!
As a result of this activity, upper elementary ocean explorers will be able to describe several interrelationships: symbiosis, mutualism, commensalism, and parasitism. They learn that the biological richness is increased near seamounts and use this type of community to find examples of each of these relationships. After discussion of these concepts, learners work in groups to research an individual seamount community member. They prepare reports to share with the rest of the class.
This project provides students the opportunity to investigate parasites as a possible cause of the observed frog deformities. It asks students to view web-based evidence and interpret whether it supports the parasite hypothesis. Students write a letter to a scientist stating their opinions and questions about the parasite hypothesis as a culminating activity/assessment.
