Growth

 Students will explore the notion of Expansion- from how a country grows to how animal and plant populations grow. Students will learn about the various populations of organisms and the role they play in the cycle of ecosystems, how plants and animals manufacture and find food, effects of the environment, adaptations, and how humans fit in. Students will make connections from these survival systems to those of humans as they examine the expansion of our country through industrial growth, inventions in transportation and communication, and immigration/migration. It is natural for a species to want to reproduce and continue to do so against all odds.
