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....
Howard Hughes Medical Institute
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...
ARKive
Invasive Species
Learn about how invasive species and introduced species impact the environment around them with a presentation and lesson plan. After viewing the presentation, learners go to the library and computer lab to look up various species and...
Cheetah Outreach
Population Change
Your youngsters become cheetahs in search of food, water, shelter, and space in a fun physical game that does a fantastic job of representing fluctuating species population based on resources available over years.
Biology Junction
Population Genetics
Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...
Curated OER
Population Ecology
A complete study of population ecology is covered by this worksheet. Biology or ecology learners answer questions and interpret population graphs. This can be used as the intended guided notes worksheet or assigned as homework.
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...

2003 AP® Environmental Science Free-Response Questions
One size fits all doesn't seem to be the right approach to endangered species. Using a four-part AP® assessment, learners respond to questions that address environmental concerns such as human population changes, invasive species...
College Board
2000 AP® Environmental Science Free-Response Questions
Practice makes perfect! A released AP® exam gives scholars practice with the high level of expectations of their exams. The exam consists of four questions from 2000. Questions ask about endangered species, recycling, alternative fuels,...

Endangered Species
Your learners have likely heard about animals going extinct. By reading this passage, they can find out some reasons why this happens and how to protect endangered species. After reading, individuals respond to five related questions.

Population Dynamics: The Predator-Prey Lab
Wolves eat better when the bunny population increases, but how long does that last? A series of 12 biology lessons uses the sixth installment to explore the predator-prey relationship between bunny and wolf populations. Young scientists...

Saving Species
Some scientists dedicate their lives to researching and protecting endangered species. An online lesson teaches about three scientists around the world who do just that. They learn about spiders, mollusks, and reptiles from North...

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...

Endangered Species
Ninth graders graph data in order to compare the number of extinct species and a rise in human population. They analyze the data collected. Students are encouraged to infer the relationship.

Population Biology
Pupils 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...
