Supplemental Resources:

The following page contains a list of the 50 United States of America. We have found it to be helpful if you collect class data on the number of States visited. On the next page is a potential blank survey that you can pass around on the first day of class to collect some data. Some of the survey questions are left deliberately vague, so that you can discuss potential sources of bias, informally of course.
