Students begin the lesson by developing a map of Kelsey Island by following specific instructions. In groups, they are given a block of ice in which they tie a rope around and drag over various rocks for different distances. They record, compare and contrast their answers. They also discover how the sea level rises when ice is put into water with their ice block. They end the lesson by discussion how this affects coastal areas. Full Review »
