College Instructor edition with experiments covering introductory and general environmental science topics.

Acid Deposition

Lab Summary

Use My World GIS and student-collected data from the GLOBE project to discern patterns of acidic pH measurements, particularly in cities in the United States.

**Requires My World GIS License.

Theory

In this activity students use student-collected data from the GLOBE project to discern patterns of acidic pH measurements, particularly in the United States. They also:

  • Explore the relationship of population centers to acidic water bodies.
  • Explore the relationship of industrial polluters to acidic water bodies.
  • Consider the effect of wind carrying acid deposition to remote areas.

Method

Students gain experience conducting the following procedures:

  • Using My World GIS (global information system) software to examine an international database of pH measurements taken and reported in a student GIS GLOBE project.
  • Correlating areas with low pH measurements with population and industrial centers.
  • Looking for patterns that give clues as to the sources of acid in the atmosphere.
