My World GIShttp://www.myworldgis.org/
My World GIS™ is a Geographic Information System (GIS) designed specifically for use in middle school through college classrooms. It was developed by the Geographic Data in Education (GEODE) Initiative at Northwestern University as part of a research program on the adaptation of scientific visualization and data analysis tools to support inquiry-based learning. My World GIS gives learners access to a variety of geographic data, enabling users to explore critical issues about the environment, geography, geology, demography, history, and much more. Its features include customizable display of layer variables, multiple geographic projections, table and map views of data, distance-measurement tools, and buffering and query operations.

My World Tool and Button Guides in pdf
The following guides can be downloaded to help with the use of the program:
United States Geological Survey (USGS) 24K Quad Datahttp://data.geocomm.com/catalog/US/group127.html (free data, requires a login)
These grids contain the quad reference number and name as maintained in the USGS Index to topographic and other Map Coverage books or Catalog of topographic and other Published Map books. These individual zip files are in an ArcView shapefile format.
National Wetlands Inventory (NWI)http://www.fws.gov/wetlands/Data/index.html
The Wetlands Data Extraction Tool uses the USGS topographic quadrangle names for area selection and extraction. If you are unfamiliar with the name of the quadrangle you wish to download you can use the Wetlands Mapper to zoom to your area of interest and view the quadrangle names. Most U.S. State datasets are available through this service.
Land Use and Land Cover (LULC)http://www.webgis.com/lulcdata.html
The Land Use and Land Cover (LULC) data files describe the vegetation, water, natural surface, and cultural features on the land surface. The United States Geological Survey (USGS) provides these data sets and associated maps as a part of its National Mapping Program. The LULC mapping program is designed so that standard topographic maps of a scale of 1:250,000 can be used for compilation and organization of the land use and land cover data. In some cases, such as Hawaii, 1:100,000 scale maps are also used.
LULC Classification Codes are described here: Appendix
Land Use and Land Cover (LULC) data are available for most of the contiguous United States and Hawaii.
