Lights, camera, action: A video that introduces the NGSS practice of scientific argumentation

Following the recommendation to incorporate the Next Generation Science Standards (NGSS) science and engineering practices in their classrooms, schools across the country are looking for ways to integrate scientific argumentation into their curriculum. Since 2012 the High-Adventure Science project in collaboration with National Geographic Education has offered free online modules for Earth and space science topics—including climate change, freshwater availability, the future of energy sources, air quality, land management, and the search for life in the universe—that include multiple opportunities for students to engage in argument from evidence.

Over 67,000 teachers and students across the globe have used High-Adventure Science modules. Based on teacher feedback, classroom observations, and analysis of student data, we have learned that when students engage in argumentation from data and model-based evidence, they need a lot of support on how to write a convincing argument.

Last year, we added an introductory activity to each module where students learn about the component parts of a scientific argument before they are asked to write one. In this highly scaffolded task, students see written examples of a claim and explanation and learn about uncertainty in scientific data and how to express this uncertainty. In High-Adventure Science, argumentation takes a special form, including a multiple-choice structured claim, open-ended explanation, five-point Likert scale uncertainty rating, and uncertainty rationale.

In this introductory activity, students learn about the components of a good explanation.

Even with this new activity, some students still struggled, so we recently created an animated video to introduce the scientific practice of developing an argument. We start by helping students identify the difference between a scientific argument and so-called “arguments” they may have with their friends (e.g., arguing about favorite ice cream flavors!), and making the distinction between claims backed by evidence and opinion. The goal is to introduce students to scientific arguments in a fun and relatable way and to make the terminology and process of scientific argumentation less daunting.

We’re piloting the video in our Will there be enough fresh water? module for select students. We’re looking forward to student and teacher feedback and may revise the video based on their comments. We want everyone to be able to engage in the critical practice of arguing from evidence.

We welcome your comments about our video, as well as your challenges and successes with incorporating the NGSS practice of engaging in argument from evidence.

The repeal of the Clean Power Plan and how to teach about energy choices and climate change

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?

 

Two “Global Experiments” about Climate Change

In an earlier post on this blog I wrote about the need to increase our knowledge of how people think about climate change and then apply that knowledge to expedite policy changes. Subsequently I discovered that there is an active community of psychologists, experts in communications and other researchers who conduct valuable inquiries in this field.

Some of their findings are sobering, such as data from April 2014 showing that only one in three Americans discusses global warming with family and friends even occasionally. One of the many reasons this is true is that for more than five years, with little variation from year to year, only about one in three Americans have believed people in the U.S. are being harmed “right now” by global warming—despite Superstorm Sandy, Hurricane Katrina, extreme drought in the West and other once-rare climate events. One does not wish for more droughts, extreme heat waves, superstorms or wildfires; however, those are the kinds of events that may, slowly, change opinions about climate change.

People who realize how threatening climate change is believe that we are conducting a risky “experiment” with the sensitivity of Earth systems to increasing levels of carbon dioxide and other heat-trapping gases. For example, we still don’t understand climate “tipping points” well; however, our global experiment is already teaching us about tipping points, like it or not.

Professor Richard Somerville of the Scripps Institution of Oceanography at UC San Diego—who was Coordinating Lead Author of the Intergovernmental Panel on Climate Change’s fourth assessment report (2007)—wrote, in his 2006 paper called “Medical metaphors for climate change,”

“What is still not obvious to many is that all of us are now engaged in a second global experiment [emphasis added], this time an educational and geopolitical one. We are going to find out whether humanity is going to take climate science seriously enough to act meaningfully, rather than just procrastinating until nature ultimately proves that our climate predictions were right.”

This educational experiment—where education is broadly defined and includes more than what is taught in schools—could hardly be more important. It will take a concerted effort, over many years, by formal and informal institutions, political leaders and organizations, TV stations, museums, churches and others, to increase knowledge and a sense of urgency among policymakers and the public. The Concord Consortium’s High Adventure Science (HAS) project is one element in this long-term effort.

The Next Generation Science Standards include climate change as an important topic for instruction, which is significant because more people need some understanding of the science behind climate change. But the “educational experiment” the world is conducting requires policymakers and the public to learn far more than science. Better understanding the economics, political, regulatory, governance, diplomatic and technology issues needed to address climate change will be vital, as will an emphasis on ethics and values. It would be interesting to know how, and how often, climate change is a topic of study in other subjects taught in schools, colleges and universities (including social science classes, like Psychology), or whether it is addressed almost exclusively in “hard science” courses.
