Instructional Ideas
  • Allow the class to choose their own locations to investigate
Classroom Considerations
  • Request time in a computer lab, as you need both Internet access and printers for the activity
  • The lesson uses the same website as in the previous lesson; it is possible to combine portions of the two activities into one lab if time is an issue

Pros
  • Resource has tables for learners to organize their data
  • Teacher guide includes a list of websites for additional information
Cons
  • Links are outdated/broken
