At the end of our ecosystem unit, fourth grade biologists worked in collaborative groups to design and construct forest floor ecosystems. The teams had gravel, soil, leaf litter, moss, ground cover, sticks, and grass seed from which to choose. Their challenge was to create an ecosystem that met the needs of their living organisms- plants, meal worms, pill bugs, and crickets. We investigated each of these animals in past labs. Our ecosystems represent a community with different populations who are interdependent with the abiotic (non-living) factors. The students brought the ecosystems back to their classrooms and placed them where they believe their ecosystems will thrive.
How do crickets chirp? Watch the video that Mrs. Denard captured.
