Limiting Factors to Population Growth: Graphing Population Growth
If any of the limiting factors in an environment change, both animal and plant populations also change. The video explains two different models of growth and the impact of limiting factors. It highlights the carrying capacity of an...
Curated OER
World Population Activity II: Excel
Students import UNEP World population data/projections from either the World Population Prospects: The 2002 Revision Population Database - UN Population Division or a text file. They graph this data by itself, and then along with...
Curated OER
Population Patterns
Students study patterns of population growth in an ecosystem and why populations must remain in balance. They interpret basic population graphs and suggest scenarios about different population growth patterns in an ecosystem.

The Dynamics of Populations
Tenth graders analyze the growth rate of different population. In this biology experiment, 10th graders identify the biotic and abiotic factors that limit population size. They create a poster to show their findings in class.

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
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.
