Students learned to identify Honeysuckle, Buckthorn and Poision Ivy (pictured below).
  
 Our guide taught us how to identify the leaf of the Poison Ivy plant by crossing our hands.  The Poison Ivy plant has “thumbs” like our thumbs pictured above.

Students played a game to demonstrate how pesticides can affect the food chain especially animals at the top.  Ospreys were unable to hatch because the mother’s eggs were  deficient in Calcium due to DDT in the food chain.  Michigan’s Osprey chick population was wiped out and the species became endangered.  They are now on their way back.
