Population Dynamics
Will human population growth always be exponential, or will we find a limiting factor we can't avoid? Young scientists learn about both exponential and logistic growth models in various animal populations. They use case studies to...

Population Biology - Biology Teaching Thesis
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...

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...

The Ups and Downs of Populations
Life has its ups and downs ... especially if you're an animal! Biology scholars engage in a population study through an inquiry-based lesson. Pupils work together to explore the factors that affect deer populations, then examine the...
Science 4 Inquiry
The Ups and Downs of Populations
As the reality of population decline across many species becomes real, pupils learn about the variables related to changes in populations. They complete a simulation of population changes and graph the results, then discuss limiting...

The Influence of Human Activity on the Environment
The surge in human population in the last 2,000 years, due in large part to better health care, has brought a surge in the demand for resources and in pollution. The graphics, photographs, and real-life examples in a thought-provoking...

Understanding and Predicting Changes in Population Size – Exponential and Logistic Population Growth Models vs. Complex Reality
Salmonella poisoning impacts over 200,000 people in the United States each year. Scholars learn about the growth of these bacteria using multiple approaches. Then they apply the same growth calculations to endangered species and think...

Biomes and Population Dynamics - Balance Within Natural Systems
How large can a population become? The fifth installment of a nine-part unit teaches young ecologists about limiting factors that determine the carrying capacity of species in the Sonoran Desert. Here is a PowerPoint to help present this...

Population Biology
High schoolers 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...

Migration Mishaps
Elementary ecologists pretend to be migratory hummingbirds. They fly between wintering and nesting grounds, trying to reach a habitat haven. In a musical-chair fashion, some birds will miss out, and are removed from the game. To further...
