6.4 How Do Humans Affect the Earth Around Us?
This module focuses on energy transfer as a mechanism for understanding issues related to global warming and climate change and the effects that humans have on both. Using land, water, air, and organisms as focal points, the module investigates how humans have impacted those components of the Earth system. Students analyze a human-impact problem and design solutions to minimize its effects, and they consider the consequences of those designs for Earth and its inhabitants. Once encountered here, climate change is able to be addressed in future modules, including its importance in sustainability, addressed in 8th grade.
