Texas Instruments: Logistic Growth
Students are introduced to logistic growth curves using a graphing calculator. Lab data includes the number of bacteria over a 20-hour period. The activity numerically approximates the derivative and uses regression to find a curve...

Teach Engineering: Population Growth Curves
Using Avida-ED freeware, students control a few factors in an environment populated with digital organisms, and then compare how changing these factors affects population growth. They experiment by altering the environment size (similar...

Concord Consortium: Population Curve: Significance of Breakpoints
Learn about three models of population growth: linear, exponential, and logistic. Then conduct a population experiment to see how populations can work in the real world, and see how linear graphs can help simplify complicated ones.
