Study Jams! Population Growth
Along came a spider, who sat down beside her. She screamed, but RJ wouldn't smash it because spiders are a limiting factor for other insects in an ecosystem. In this video, other common limiting factors for populations are listed....

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...

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 Growth
A single slide depicts the normal population growth curve. The curve reaches a steady state when the population reaches carrying capacity. You can use this slide when teaching about populations, but it may be more effective to insert it...

Population Ecology
A complete study of population ecology is covered by this activity. Biology or ecology learners answer questions and interpret population graphs. This can be used as the intended guided notes activity or assigned as homework.

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...

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...

Some Similarities Between the Spread of an Infectious Disease and Population Growth
Students compare and contrast the spread of infectious diseases and population growth. For this biology lesson, students identify the exponential growth pattern of spreading diseases. They relate this to HIV infection and AIDS.

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...

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...

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...
