Rock Art in the National Parks Activity Source: Views of the National Parks, National Park Service. Adapted with permission. Human beings have been linked to earth materials since prehistoric times. They used caves for shelter, shaped rocks into stone implements, and later refined metals to make tools. Beyond practical purposes, Earth materials also were used to make pigments for paint. Rock walls became canvases where ancient artists expressed themselves. In this exercise, we will explore the link between Earth materials and art. [Read More]

Sea Level and the Terrapin Activity Source: U.S. Environmental Protection Agency. Adapted with permission. The diamondback terrapin (Malaclemys terrapin) is the only North American turtle fully adapted to life in brackish water (mix of saltwater and freshwater). Its home is in coastal salt marshes of estuaries along the Atlantic and Gulf coasts of the United States. Although they can live 40 years or more, most turtles do not make it to their first birthday, because they are prey for foxes, otters, raccoons, skunks, and birds. [Read More]

Soil Color and Redox Chemistry Activity Source: Soil Science Society of America. Adapted with permission. Are soils like M&Ms™? Yes! Typical soil colors are red, brown, yellow, or black. These colors are often not the color of the minerals in the soil but coatings of iron oxides (Fe203, FeOOH, and so on) or organic matter on particles. The minerals beneath are often quartz or feldspar, which are grey. To see how coating affects soil color, consider red M&Ms™. [Read More]

Solar Cell Energy Nationwide Activity Source: Adapted with permission by NASA. MY NASA DATA microsets are created using data from NASA Earth science satellite missions. A microset is a small amount of data extracted from a much larger data file. Data is available on the atmosphere, biosphere, cryosphere, ocean, and land surface. Data and related lessons can be used with existing curriculum to help students practice science inquiry and math or technology skills using real measurements of Earth system variables and processes.

Traveling Nitrogen Activity Source: Windows to the Universe. Adapted with permission. Nitrogen is an element that is found both in living things and the nonliving parts of the Earth system. In this classroom activity, students play the role of nitrogen atoms traveling through the nitrogen cycle to gain understanding of the varied pathways through the cycle and how nitrogen is relevant to living things. For the teacher: To prepare, set up nitrogen reservoir stations around the classroom (or outside). [Read More]

Using Global Earth Science Data Activity Source: NASA Background With the use of cutting-edge remote sensing technologies, NASA can collect a wealth of data that offers a comprehensive understanding of the dynamics of our planet. This data ranges from monitoring land cover changes and oceanic currents to deciphering climate patterns and atmospheric composition through an intricate network of satellites, ground-based sensors, and aerial platforms. The My NASA Data visualization tool, the Earth System Data Explorer (ESDE), helps learners visualize complex Earth System data sets over space and time. [Read More]

Your Own El Nino Activity Source: Adapted with permission by the National Weather Service from Discover Your World with NOAA: An Activity Book Background El Niño storms have taken thousands of lives and caused billions of dollars in damage in recent decades. Where do these storms come from? Every two to seven years, trade-winds in the Pacific Ocean slow down or reverse their direction — no one is sure why. [Read More]
