History of Populations: The activities at this
level focus on studying a series of circle graphs
that report the population of the United States and
of selected states–Massachusetts, New York, and
Pennsylvania–in fifty-year intervals from 1800 to
1950. The students are asked to discuss and
describe the information and to explain why the percent
of the total population changed for the three states. They
are asked to write a justification for their explanation.
