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....

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...

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...
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...
McGraw Hill
Population Biology
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...

AP: Chapter 52: Population Ecology
For AP biology or ecology classes, here is a worksheet that explores population growth. Carrying capacity, limiting factors, and k-strategies are dealt with using short-answer questions.Â

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...

Factors Affecting Population Size
How do we predict future population growth? Young researchers investigate various factors affecting the size of our population. As they calculate and interpret graphs to determine factors that could potentially affect increases and...

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...

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.

Population Growth in Yeasts
Students design an investigation using yeast. In this environmental engineering lesson, students design an investigation to determine how environmental factors affect the growth of yeast. They will collect quantitative data and discuss...

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
Students 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.
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...

Plant Science Chapter #1
It may not stand as a cohesive presentation, but individually you may find a use for these slides. One slide describes how civilization began once man learned to plant and harvest food. Another explores the population growth over time....

Population Biology
Students 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. In 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...

Human Population Growth
In this human population growth worksheet, students create a graph of human population growth and predict future growth using the data given in a chart. Students identify factors that affect population growth.

Some Similarities between the Spread of an Infectious Disease and Population Growth
If the infectious diseases and population growth worksheet, students simulate the spread of an infectious disease by exchanging fluids in a lab activity. Students watch the spread of the disease and graph the spread of the disease vs....

Population Patterns
Students 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.

Population Dynamics
Young scholars 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
Learners 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...
