Celebrate Wilderness Activity Source: U.S. Fish & Wildlife Service. Adapted with permission. The Wilderness Act, signed into law September 3, 1964, celebrates its milestone 50th anniversary in 2014. The legislation poetically defines this natural resource: “A wilderness, in contrast with those areas where man and his own works dominate the landscape, is hereby recognized as an area where the earth and community of life are untrammeled by man, where man himself is a visitor who does not remain.

Chemistry of Burning Activity Source: The University of Texas at Austin Bureau of Economic Geology. Provided by Association of American State Geologists. Adapted with permission. Why is CO2 increasing in the atmosphere? Who is doing it? Many people think that CO2 is “pollution,” so that clean burning should be a way to eliminate greenhouse gas emissions. In this demonstration, we review basic chemistry (see illustration) to realize that producing CO2 is an inevitable product of burning any fossil fuel. [Read More]

Chocolate Rock Cycle Activity Source: The Geological Society of London. Adapted with permission. How sweet is this activity? It’s an introduction to the rock cycle using chocolate! Chocolate can be ground into small particles (weathered), heated, cooled, and compressed — just like rocks. Unlike rocks, chocolate can undergo these processes safely and at reasonable temperatures. Use your chocolate to create “sedimentary,” “metamorphic,” and “igneous” chocolate. And at the end of it all, make a tasty treat! [Read More]

Citizen Science Activity Source: Adapted with permission by National Oceanic and Atmospheric Administration. How are people affecting your local environment? How is our planet changing? Join the “citizen science” movement, and you can help discover the answers. Citizen science is a form of open collaboration in which members of the public participate in the scientific process to address real-world problems. Volunteers can work with scientists to identify research questions, collect and analyze data, interpret results, make new discoveries, develop technologies and applications, as well as solve complex problems.

Clear as Black and White Activity Source: American Geosciences Institute What are some of the factors that might unnecessarily exclude people from learning about or working in the geosciences? Culture? Ethnicity? Sex? Language? A disability? Where they live? How much they earn? Something else? Let’s examine a disability-related factor. Considering the important role that color plays in many geologic maps, one might suppose that color blindness would prevent a person from reading or using geologic maps. [Read More]

Climate and Temperature Activity Source: Soil Science Society of America. Adapted with permission. There are many factors that combine to form soil, an important, slowly renewable resource. Some of these factors include climate, organisms, relief, parent material, and time. Soil provides the food, fiber, and building materials to nourish, clothe, and house Earth’s inhabitants. How does climate help soil to form? In warm, moist climates such as those in tropical rainforests, organic (formerly living) material breaks down most quickly. [Read More]

Climate Change and Resilience Activity Source: Earth Science Information Partners (ESIP). Created by the ESIP Education Committee using materials from Climate.gov. Adapted with permission. The United Nations advocates for 17 Sustainable Development Goals (https://sdgs.un.org/goals), one of which includes taking urgent action to combat climate change and its impacts. Climate resilience is the capacity of a community, business, or natural environment to retain essential functions before, during, and after changes to climate occur. [Read More]

Collecting Real World Data Activity Source: National Aeronautics and Space Administration. Adapted with permission. Scientists collect data to understand Earth and how it changes. Quantitative data involves taking measurements, while qualitative data are observations and descriptions of phenomena. When it comes to climate, scientists try to collect as much and as many types of data as possible to be able to analyze how climate is changing and what effects it is having. [Read More]

Composting Materials and Rates Activity Source: Geological Society of America. Adapted with permission. Activity authored by Jessie Bersson (Arizona State University), Carla McAuliffe (TERC), and Matt Dawson (GSA). (Inspired in part by an activity at www.sciencebuddies.org) Soils are a key component of the interface between the biosphere (life) and the geosphere (land). Soils support life.“Our soils support 95 percent of all food production, and by 2060, our soils will be asked to give us as much food as we have consumed in the last 500 years,” according to Living Soil by The Soil Health Institute.

Connect the Spheres Activity Source: Adapted with permission by National Aeronautics and Space Administration, Global Precipitation Measurement Mission. This activity will provide you with an introduction to a series of lessons — Survivor Earth — about water resources on Earth. You’ll investigate Earth systems by making observations in nature and identifying systems in the natural world. Ultimately, you will understand how the four spheres, or systems, on Earth — biosphere, hydrosphere, geosphere, and atmosphere — are interconnected. [Read More]
