In this online unit your child will examine and identify the causes of change in nature. He will explore the effects of heat, from stove tops to volcanoes, and learn about endangered and extinct animals species. To understand the impact that humans can have on a natural environment, he will follow the course of a river through generations.
This unit can be used independently, but it is designed to be used concurrently with the literature unit, Morning Girl.
