![]() ![]() Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth’s systems. * Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment. ![]() Construct a scientific explanation based on evidence for how the uneven distributions of Earth’s mineral, energy, and groundwater resources are the result of past and current geoscience processes. This unit builds toward the following NGSS Performance Expectations (PEs): Students work through a systematic evaluation process to consider (1) each solution’s potential to solve the carbon imbalance, (2) tradeoffs associated with solutions based on student-identified constraints, and (3) whether the solution in question makes sense for their community’s stakeholders. The unit ends with students evaluating different kinds of solutions to these problems and how they are implemented in communities. Students figure out that the rising temperatures are caused by an imbalance in Earth’s carbon system, resulting in a variety of problems in different communities. They use evidence to support a scientific explanation that two climate variables (temperature and precipitation) are changing precipitation patterns in the case sites they investigated. Students spend the first lesson set gathering evidence for how a change in temperature affects evaporation, precipitation, and other parts of Earth’s water system. This initial work sets students up to ask questions related to the query: How do changes in Earth’s system impact our communities and what can we do about it? This prompts them to develop an initial model to explain how rising temperatures could cause both droughts and floods and leads students to wonder what could cause rising temperatures, too. Students figure out that these drought and flood events are not normal and that both kinds of events seem to be related to rising temperatures. This unit on Earth’s resources and human impact begins with students observing news stories and headlines of drought and flood events across the United States. 7.6 Earth’s Resources & Human Impact How do changes in the Earth's system impact our communities and what can we do about it?
