Maine Edge advances 4-H Science Saturday on soil, extinctions

The Maine Edge reported the connection between fire, people, soil and extinct foxes is part of a University of Maine Cooperative Extension 4-H Science Saturday from 10 a.m. to 1 p.m. Oct. 24 at Sawyer Environmental Research Center. Youth in grades six through eight will learn to use a coring device to collect soil sediments that are thousands of years old. Sediments give a snapshot of past ecosystems, as well as extinctions and how humans interacted with and changed the environment. Participants will obtain data from the cores and learn how past fires affected the environment and wildlife.
