Population Patterns

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...

The total world population is predicted to pass 8 billion by 2025, which is less than 10 years from now. The video focuses on human population growth and the impact it has had and is having on our planet and other populations. It...

With a human population of 7.6 billion and counting, how do we tackle the population problem? Examine the data using a video from an extensive science playlist. The resource explains why the human population began to increase rapidly,...

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....

[Free Registration/Login may be required to access all resource tools.] Students will identify the definition of carrying capacity and analyze other types of growth patterns of a population and relate these to the population dynamics of...

Explore growth patterns in wildlife populations.

The carrying capacity of an environment varies based on the organisms that live there. Using a virtual lab simulation, scholars test two protists living in their own environments and a third environment where both protists live. They...

Using Avida-ED freeware, students control a few factors in an environment populated with digital organisms, and then compare how changing these factors affects population growth. They experiment by altering the environment size (similar...
