Population Patterns

A beautifully written lesson plan delves into a beautiful topic: stellar population. Engage aspiring astronomers with activities that examine human populations and then transition onto the stars of the universe. Data and photographs for...

The "Bottled Bacteria" activity instructions are a bit unclear, but the remaining activities investigating limiting factors in ecosystems are well-written. Learners model the exosystem of a bear and a herd of deer. They set up a...

There was a situation in the Kaibab desert of Arizona during which the deer population exploded. Wildlife biologists examine historical data using a graphing calculator in order to learn about population growth, limiting factors, and...

Introduce ecology and focuses on the first three levels: populations, communities, and ecosystems. An engaging presentation includes descriptions of exponential growth, population density, adaptations, depression versus baby boom,...

Build up from the previous activity where your learners charted the population growth and decay of a fish pond with M&Ms®. Have them look at the data from that activity and create a Now-Next, or recursive equations, to predict the...

An abused captive or a treasured performer? Class members conduct an analysis of arguments presented by both sides regarding the captive killer whale population, labeling those claims that can be supported and those that need additional...

Students examine how populations grow and how invasive species can affect the balance of ecosystems. They simulate the growth of lily pads, analyze and record the data, and simulate the results of an invasive species on an ecosystem.

Students define the following terms: predation, competition, carrying capacity and population. They can explain the patterns of growth and the limitations of growth. Students explain the difference between density-dependent and...

Students explore the effects of different density-dependent and density-independent factors on population growth. They explore how the interactions of organisms can affect population growth. Students explore the pattern of population...

Students investigate the factors affecting population growth. In this biology activity, students collect data from the lab and graph them. They estimate population size using a mathematical formula.
