Population Dynamics (Day #1 of 3)

Unit 7: 7) Ecology ("Population Interactions")
Lesson 4 of 16

Objective: Students will be able to explain how the complex set of interactions within an ecosystem can keep the numbers and types of organisms relatively constant over long periods of time under stable conditions. Students will also understand that, when encountering instability, populations can be resilient or severely challenged.

Big Idea: Populations of species are influenced by the abiotic and biotic factors present in the environment. However, feedback mechanisms help to adjust a population's size toward its "ideal" level.

Big Idea: Students get to run around and have fun pretending to be rabbits; snakes, hawks and grass, while learning firsthand how environmental factors have a great effect on an organism's ability to survive.

Big Idea: Counting every individual in a population is almost always impractical if not impossible. Ecologists can use sampling methods to make reasonable estimates of population sizes.
