Students will create three graphs about population distribution: a line graph showing human population milestones, a bar graph of the top ten most populated US cities, and a pie graph of the top ten largest cities worldwide. The class will discuss the impacts of human population growth, then divide into six groups of four students each to research major population milestones like when the world reached 1 and 2 billion people. Groups must submit their names to the teacher via a shared server before beginning research using the provided links.
