Limiting factors and models of population growth (1 of 2)

Environmental Stewardship by Design » Unit: Populations

Daniel Babauta
New York, NY
Environment: Urban
 
Big Idea:

Factors that affect population size can be density-dependent or density- independent. How might we use modeling to understand the impact of each type of factor on population growth?

Sharon Wilson
Jonesboro, GA
Environment: Urban
 
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.

Population Dynamics (Day #1 of 3)

High School Biology » Unit: 7) Ecology ("Population Interactions")
High School Biology » Unit: 7) Ecology ("Population Interactions")
Mitchell  Smith
Kent, WA
Environment: Suburban
 
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.

SKILL BUILDER: Exponential and logistic growth

Environmental Stewardship by Design » Unit: Populations
Environmental Stewardship by Design » Unit: Populations
Daniel Babauta
New York, NY
Environment: Urban
 
Big Idea:

Under ideal conditions, every population has a particular maximum growth potential in the shape of a J-curve, but under normal conditions population growth levels off. How might we model exponential and logistic growth using real-world populations?

Environment: Urban
 
Big Idea:

How fast a population grows is determined by the amount of resources available.

Population Explosion (Yeast Lab) (Day #1 of 3)

High School Biology » Unit: 7) Ecology ("Population Interactions")

Mitchell  Smith
Kent, WA
Environment: Suburban
 
Big Idea:

Populations are able to produce populations of infinite size, but the environment (and its resources) is finite.
