Trophic Cascades Modeling Task (assessment in the style of NGSS)

I love this activity because it REALLY forces students dig into one of two really cool ecosystems--Yellowstone or Isle Royale. Prior to this activity, my Enviro Sci students spend some time learning about keystone species, invasive species, trophic cascades, food webs, top down/bottom up control, and the idea of interdependence.
