The five national marine sanctuaries along the West Coast monitor the health of the rocky intertidal ecosystem. One way of doing this is to collect data on the relative abundance of the organisms living in that ecosystem. Since this is such a big task, the national marine sanctuaries are training students in how to follow standardized protocols to help with the monitoring. The information collected is added to an online database that the sanctuaries use to collect baseline data and track long-term changes in the environment. This activity will allow you to learn the sampling techniques used in the field by these citizen scientists who participate in LiMPETS.
Learn about fossil preservation, paleontology, and stratigraphy in this detailed activity from the USGS.
Natural gas, which is mostly methane, is an energy resource used for generating electricity and heating, powering transportation, and manufacturing products. Right now, one-quarter of the world’s energy comes from natural gas. In this investigation, you will make a simple model of how gases can form from decaying material. You will also explore the effects of temperature on gas formation.
In this activity, students will learn the pattern of major ocean currents and how they are changed by wind, land and water.
Citizen scientists involved in the Geological Society of America's EarthCaching project (http://www.earthcache.org) use GPS technology and latitude and longitude coordinates to find special places on the Earth. This activity will help you learn how to find locations using latitude and longitude.
Students can monitor local ozone by looking in their neighborhoods for ozone-injured plants or establishing similar gardens outside their schools or in their backyards.
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.
What is sea ice? It is simply frozen ocean water. Why is sea ice important? While it occurs mainly in polar regions, sea ice influences our global climate. Changing amounts of sea ice can affect ocean circulations, weather patterns, and temperatures around the world. Sea ice insulates the relatively warm ocean water from the cold polar atmosphere, except where cracks in the ice allow for the exchange of heat and moisture. The exchange of salt between sea ice and the ocean alters the density of ocean waters, thus influencing ocean circulation. Many animals, such as polar bears, seals, and walruses, depend on sea ice for their habitat. These species hunt, feed, and breed on the ice. Satellites provide the best way to observe sea ice, the factors that affect sea ice, and the ways sea ice affects global climate. Scheduled to launch in 2010, NASA’s Aquarius mission will measure global sea surface salinity with unprecedented resolution. Even small variations in sea surface salinity — the amount of salt present near the ocean’s surface — can have dramatic effects on sea ice, the water cycle, and ocean circulation.
This activity allows you to investigate how often earthquakes of various magnitudes happen within a geographic region of your choice. You will use the online resources of the Incorporated Research Institutions for Seismology (IRIS) to do the investigation. These resources are available at http://www.iris.edu
In this activity, students will conduct experiments or participate in demonstrations to answer questions about sky and weather phenomena. Students also will analyze and present data.
