This group activity will help students understand the population graphs and carrying capacity. It has them simulate the changes that could occur in the boreal forest between the snowshoe hare and the lynx. Students graph the changes in population as well as place the paper hares and lynxes into a forest. This allows them to see the changes in two ways. Students will see the fluctuations that occur and will see the meaning of carrying capacity. This topic is in line with the NGSS science standards.
