Population in areas is most often determined by environmental factors. This video and the test will help ensure understanding of the trends of population growth with scientific evidence.
Concord Consortium
Concord Consortium: Dam Removing: Changes in the Environment Affect Population
What happens to a population when the environment changes? Students remove a dam that divides an ecosystem to illustrate the effects of environmental changes. Students observe and collect data as the grass and then the rabbit populations...
