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...

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...

Calculating Population Growth for a Region
Students research population growth of regions of Canada. In this Social Studies lesson, students use included links on the Internet to find information about population growth in areas of Canada. A worksheet for each region is included....

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...

Bacteria and Exponential Growth
It's scary how fast bacteria can grow — exponentially. Class members solve exponential equations, including those modeling bacteria and population growth. Lesson emphasizes numerical approaches rather than graphical or algebraic.

Displaying Populations: Jellybeans, Paper and People
Young scholars investigate the factors affecting population growth. In this biology lesson, students collect data from the lab and graph them. They estimate population size using a mathematical formula.

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...

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...

Logistic Growth
Through the exploration of population growth of a bacteria population, high schoolers learn about and observe bacteria population over a 20 hour period. Students graph the population growth using a scatter plot and discuss its...

Population Patterns
High schoolers study patterns of population growth in an ecosystem and why populations must remain in balance. They interpret basic population graphs and suggest scenarios about different population growth patterns in an ecosystem.
Curated OER
Population Dynamics
Students investigate the causes and consequences of population growth and the envrionmental factors that contribute to it. They discuss what they think the world's population will be in 2050.

Population Growth
Students grow duckweed, observe what happens when an organism population is allowed to grow without predation or competition, view videos about invasive species, and develop a proposal for controlling the growth of an invasive species in...

Pandemics and Epidemics
High schoolers evaluate data related to population growth, along with problems and soultions: disease cvontrol. They are able to explain how changes in habitat may affect organisms. Students evaluate evolutionary theories and processes.
