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.
Paleontologists are the geoscientists who discover and study fossil evidence of past life. Sometimes they even find the footprints of dinosaurs that roamed the surface of the Earth long ago. Ever wonder how paleontologists are able to determine, based on fossil evidence, whether a particular dinosaur was walking or running when it left footprints behind? These two activities will help you to learn how these scientists can do that.
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.
People depend on their energy resources, so they need to know how to use them wisely. How do you think people can use the energy they rely on to heat their homes more efficiently?
Each group will design a water filtration system and present to the class, why they picked their design.
Water on earth is used over and over. The water cycle, the continuous movement of water from ocean to air and land then back to the ocean in a cyclic pattern, is a central concept in meteorology.
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.
To learn about sedimentary rock layers that we cannot see, geoscientists drill and bring up core samples of rock layers. Information from core samples, combined with that from other imaging techniques, allows geoscientists to map the depth and thickness of sedimentary rock layers below the surface. This activity will help you understand what's beneath the Earth's surface.
Learn to identify fire risk factors for a property located near a wildland area.
