The Clean Power Plan, which sets state-by-state targets for carbon emissions reductions, has been called a climate game changer, but the director of the Environmental Protection Agency, Scott Pruitt, has repealed the plan to curb greenhouse gas emissions from power plants.
Over the last several decades there has been an increasing awareness of the ways humans affect Earth’s systems. To understand the impact of policy changes, it is important to understand the core science concepts and the role of human activity. With this latest decision by the EPA, there is no better time to learn about energy choices and the future of Earth’s climate.
The Concord Consortium’s High-Adventure Science project has developed six free, high-quality curriculum modules in collaboration with National Geographic Education for middle and high school classrooms. One module explores the question “What are our energy choices?” Another investigates “What is the future of Earth’s climate?”
In the climate change module, students explore interactions between factors that affect Earth’s climate. Students analyze temperature data from ice cores, sediments, and satellites, as well as greenhouse gas data from atmospheric measurements. They also run experiments with computational models and hear from a climate scientist working to answer the same question about the future of the Earth’s climate.
The NASA Goddard Institute for Space Studies video shows the changes in Earth’s temperature across the globe between 1884 and 2012, compared to the baseline temperature between 1950 and 1980.
In the energy module, students explore the advantages and disadvantages of different energy sources for generating electricity with a particular focus on natural gas extracted from shale formations through the hydraulic fracturing (“fracking”) process. Students examine real-world data to learn about electricity consumption trends worldwide, and use an interactive with data from the Energy Information Administration to investigate the sources of electricity in their state (and across the U.S.) from 2001 to 2010.
Explore some ways that an aquifer can be contaminated by drilling for shale gas. Click the About link in the upper right of the model for instructions to create a drill, set off explosions to fracture the shale layer, fill the pipe with water or propane to hydraulically fracture the shale further, and pump out the fracking fluid.
When considering our energy future and how that impacts climate change there are no easy answers. Many factors need to be considered when making energy choices. The choices we make—whether locally, nationally, or globally—have direct and indirect effects on human health, the environment, and the economy. How do you teach your students about energy choices and the future of Earth’s climate?
