Want to be an archaeologist without leaving your school? No problem! Use a computer to become a space archaeologist (no spacesuit required)!
As a citizen scientist, you can take your own air temperatures with an outdoor thermometer and compare your readings to the official ones from the National Weather Service. It is important that you follow the correct procedures, however, for placing your thermometer. This activity will help you to do that, as well as find out what the normal yearly average temperature is for each day.
Various types of sediments, or “surficial features,” lie above the bedrock in many places. The following activity shows how a visualization map of surficial features can be used to consider the interactions of the geosphere, hydrosphere, biosphere, and atmosphere.
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.
The following activity can leverage SeisMac technology to help students understand how a seismometer records ground motions.
No matter where we are on Earth, we can observe changes in vegetation. Some changes are drastic, such as going from dormant to full growth during a temperate winter.
Vegetative growth is dependent on both surface temperature (which influences soil temperature) and precipitation (which influences soil moisture). Together these environmental variables help determine the beginning, duration, and end of the growing season; the latter marked by leaf senescence, when leaves of deciduous trees die and turn colors.
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.
The Gravestone Project, part of the global citizen science program called EarthTrek (www.goearthtrek.com
), is seeking volunteers to visit cemeteries around the world and collect scientific data on how marble gravestones are weathering.
Learn about ocean currents and systems in this activity from NOAA.
Students will observe fault movements on a model of the earth's surface.
