The 4th graders led the Eco-Fair as a service learning project.  They studied four themes: bugs, soils, vermicomposting, and watersheds.  Each of the 4 fourth grade classes led one booth at the Math Night and Eco-Fair and taught students from all grade levels and their families about what they learned in class.  Seventy-five students attended with their families bring the total in attendance to 200 participants.
