In this activity, you’ll identify plate boundaries as well as continents, countries, and bodies of water to become familiar with an area known as the “Ring of Fire.”
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. Then everyone can compare their rocks to the ones found on Mars.
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.
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.
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.
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. They are also critically useful in other ways, such as in making wise land use decisions.
In 1972, NASA launched a special satellite called Landsat that contained a new camera designed to take pictures of the Earth. Why was this satellite so incredible? Well, it could take a series of pictures of almost the entire Earth over and over again, season after season, month after month, year after year. You will be seeing Landsat images in this activity and learn how to interpret them.
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.
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?
The Integrated Ocean Drilling Program (IODP), an international marine research program, offers a unique perspective on these issues. Like many research organizations, IODP sends press releases about scientific discoveries to the media that you may eventually read, hear, or see reported. This activity will use IODP as an example to help you find ways of checking science news stories for accuracy.
