Here is an exciting exploration of a fascinating topic for your emerging ecologists: bird migration! They begin by visiting the US Fish & Wildlife Service website to discover which Arctic birds come to their areas. They are assigned one of those birds and sent off to do a bit of background research on it. They use an online distance calculator to discover how far that bird migrates and use critical thinking to predict what difficulties may lie along the path from one place to another. Though the lesson claims to be written for high schooler, it is easily adaptable to preteen groups.
