Map of surface temperature changes influenced by ground cover displayed in an example in My World. Click on image for larger view.
While the specific details of each local study will vary, this example shows what a completed GIS project may look like. This project shows how surface temperatures change as the type of ground cover varies on a school campus. While this study has been done on a small scale, the results allow users to form hypotheses about the larger-scale implications of their findings.
The My World Tour window provides a way for users to communicate their conclusions or introduce their GIS project. The map view contains a satellite image of the local area and the plotted data, which are visually represented according to a color, size and/or shape scale. The table(s) of data can be viewed and edited from within the project file. Additionally, projects can contain links to images, documents, and websites.
After completing this chapter, students will be able to:
- design an experiment;
- collect and record geospatial data;
- analyze geospatial relationships in a GIS;
- communicate information in a GIS; and
- draw conclusions to an environmental question.
- If another body of water is nearby, students could map water quality data.
- Students could bring in samples of soil and/or water from their own homes to test in the classroom, and then this data could be mapped for analysis.
- If students live in different water districts, it may be interesting to compare the qualities of their drinking water.
- Students could map atmospheric data on campus over time.
- If the campus is in an urban area, it may make sense to monitor certain air pollutants.

- Students apply digital tools to gather, evaluate, and use information.
- Students use critical thinking skills to plan and conduct research, manage projects, solve problems and make informed decisions using appropriate digital tools and resources.
A minimum of three 50-minute periods.
Depending on the instructor's level of experience with GPS/GIS and My World, preparation time will vary. The instructor should take time time to become familiar with My World functions and to practice collecting GPS data and importing into My World.
