Average Review Ratings (Poor to Excellent, 1-5 scale):
Description: This site allows students to find information about various countries around the world and to create graphs that compare
various items, such as CO2 and NOx production. Good for comparative background information of sources of differing
pollutants.
Summary of Reviews
Reviewer: Kirsten Butcher
Comments: Overall, this is a useful site in which students can explore statistical information on a variety of topics organized by
nations. Environmental data is included (e.g., CO2 emissions, CO2 pollution) but educators will need to support
students in building their understanding of different data types (e.g., what is an "ecological footprint") so that they can
complete meaningful comparisons and create meaningful graphs. Some educators may find the available environmental
statistics to be limited—information like temperature and rainfall is not included. Educators will want to become familiar
with the data types and the options for exploration before turning their students loose on the site—the options can be
dizzying and some students may have trouble developing useful representations.

Reviewer: Ellen DeBacker
Comments: This site would be a wonderful resource for students when they are comparing the impact of various regions of the
world on the global warming problem. Choices are available for multiple factors in the global warming issue, from CO2
and NOx emissions to land cover. These choices can then be graphed by the countries of choice to see the differing
impacts. This would be a good site to create graphs for use in presentations that would help back up experimental
findings of the students.
