Ring of Fire

Ring of Fire Activity Source: National Park Service. Adapted with permission. A plate boundary is a line on a map that defines the edge of a tectonic plate, usually indicating where one plate meets another. Plate boundaries are further divided by the direction that they are moving relative to one another. When plates are moving towards one another, the point of contact is called a convergent plate boundary. When plates are moving away from each other, it is called a divergent plate boundary.

Rock Around the World

Rock Around the World Activity Source: National Aeronautics and Space Administration and Arizona State University, 2006. Adapted with permission. Background Scientists need your help. Those studying Mars are asking students from around the world to help them understand “the red planet.” Send in a rock collected by you or your classroom from your region of the world, and NASA scientists will use a special tool like the one on the Mars Rover to tell you what it’s made of.

ShakeAlert Earthquake Early Warning

ShakeAlert Earthquake Early Warning Activity Source: U.S. Geological Survey, Adapted with permission. Have you ever felt an earthquake? What was it like? Where were you? What did you do? More than 143 million people are exposed to potentially damaging shaking in the United States. When an earthquake happens, seismic waves travel outward in all directions. Primary (P) waves travel faster than secondary (S) waves, which do most damage. But electronic information can be sent faster than P and S waves. [Read More]

Survey Mark Hunting

Survey Mark Hunting Activity Source: National Oceanic and Atmospheric Administration. Adapted with permission. Geodesy is the science that measures and represents the size and shape of Earth. In the United States, survey reference points are developed and maintained by NOAA’s National Geodetic Survey (NGS). In this activity, you will find data on the location and description of survey marks in your area and—if you like—search for them through a variation of geocaching. [Read More]

Systems in Earth Science

Systems in Earth Science Activity Source: Adapted with permission by SEED (Schlumberger Excellence in Educational Development). What systems can you find within the Earth sciences? How do they work? How do they interact with each other? Within its new online Earth sciences theme, SEED has collected articles, activities, animations, and simulations to highlight the many systems of Earth. For example, the water cycle represents a system. A part that is often neglected is groundwater. [Read More]

Texas Rocks

Texas Rocks Activity Source: Houston Geologocial Society. Adapted with permission. Geologic maps can tell you a lot about the rocks beneath your feet. You can use the legend with the map to figure out what rock types are in various geographic areas. The legend can also tell you in what geologic period those rocks formed. Geologists use such maps to help identify where natural resources are and where natural hazards are likely to occur. [Read More]

Third From the Sun

Third From the Sun Activity Source: “Third From the Sun,” University of California at Berkeley, 2001. Adapted with permission. Background Since our beginnings, we humans have had a narrow view of our home - Earth. For many years, standing on the ground and looking around or climbing a mountain and squinting down were the most useful ways people had of trying to understand the planet’s surface. Only in the past few hundred years have we been able to better understand what the planet really looks like. [Read More]

What Covers Our Land?

What Covers Our Land? Activity Source: NASA, Adapted with permission. Looking at Earth from space is inspiring. All of the colors you see in a satellite image tell you a lot about the world around us. What is on the land around you? Pavement? A grassy lawn? A forest? What covers our land matters because we depend on and pasture to produce food, forests for wood products, plants for clean air, and water to support wildlife. [Read More]

What Lies Beneath the Upper Crust?

What Lies Beneath the Upper Crust? Activity Source: JOI Learning, 2006. Adapted with permission. Background Bombarded by Web sites, the evening news, newspapers, and popular magazines, citizen scientists often have to interpret scientific information directly from the media. Sometimes this can be a confusing process. How can you, as a citizen scientist, figure out whether science information you get from the media is reliable? More importantly, how can you find out what the information means for your life and the decisions you make? [Read More]
