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....

Here is a very interesting graphic of a world map where each country's size is adjusted accordingly to its population. The bottom row of the document also includes several maps depicting the major shifts and growth of the world...

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...

There was a situation in the Kaibab desert of Arizona during which the deer population exploded. Wildlife biologists examine historical data using a graphing calculator in order to learn about population growth, limiting factors, and...

Math and M&Ms® go great together when introducing a modeling activity. Allow your learners to simulate population growth and decay of fish in a pond and share their reasoning for the change in fish. With such an impact we have on our...

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,...

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...

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...

How fast is a city's population growing? Viewers of a short video learn to apply the slope formula in a population growth context. They see how to describe the population increase in people per year—a great example of math in the real...

For AP biology or ecology classes, here is a activity that explores population growth. Carrying capacity, limiting factors, and k-strategies are dealt with using short-answer questions. 

Young scholars design an investigation using yeast. For this environmental engineering lesson, students design an investigation to determine how environmental factors affect the growth of yeast. They will collect quantitative data and...

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....

How do populations interact with one another? Identify the different types of interactions and how population sizes fluctuate and affect one another using an interesting PowerPoint presentation. Learners explore real-world examples of...

In this exponential population growth learning exercise, students read word problems and determine the exponential growth of a specified populations.  They find the percent of growth and compute exponential regressions.  Students graph...

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.

Students examine both historical and recent estimates of world population. They identify regions of the world that have had significant population growth in the last decade and speculate on reasons for this.

Students create linear, exponential, and quadratic models of U.S. population data to determine which function best represents U.S. population growth. They predict future populations based on each model.

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...

High schoolers explore the concept of population growth. In this population growth lesson, students graph the population growth of a 'calcumite' which is a made up species whose population grows exponentially. High schoolers plot the...

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...

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.

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

Young scholars discuss the following terms and their definitions: zero population growth, population density, demographics, urban sprawl, census, immigration, migration, infrastructure, population booms, megacities, birthrate, death...

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....
