Background Reading: Demography in Action
Unit Lesson Plans:
All in the Family: Students use beans to model population growth in one of seven different countries while varying four key demographic factors.
Measuring a Million: Through riddles and cooperative learning math activities, students work through problems to calculate and visualize millions and billions of things and people.
Double Feature: Students use mathematical formulas to calculate growth rates and doubling times, and to determine the difference between arithmetic and geometric growth.
Everything Counts: Acting as store owners, students conduct a mini-census to identify their potential market and then use different estimation strategies see how construction of their store will impact a local population of threatened mice.
The Stork and the Grim Reaper: In a short demonstration, students observe how populations grow when the birth rate exceeds the death rate.
Power of the Pyramids: Students construct and interpret population pyramids for six countries and discuss differences in the population growth rates of each.
Pop Ecology Files: Students graph and interpret growth curves for six mystery species and humans.
Panther Hunt: Students gain an understanding of carrying capacity when they act as predatory animals in a finite area and attempt to accumulate enough food to stay alive.
More the Merrier?: Students demonstrate the effects of crowding in a “jumping jack” activity, discuss the pros and cons of population density, and analyze a United States population density map.
