Overpopulation

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...

Open learners' eyes to the challenge of finding safe drinking water – something we often take for granted in our country. The PowerPoint presentation includes images, graphs, diagrams, and even a video to stimulate discussion on how we...

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...

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,...

The population of the US increased 300 percent in the 20th century, but the use of raw materials increased by 1,700 percent. Explore human population growth over time with a video that examines the history of why such growth has occurred...

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...

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...

Students examine how populations grow and how invasive species can affect the balance of ecosystems. They simulate the growth of lily pads, analyze and record the data, and simulate the results of an invasive species on an ecosystem.

Study the ways that humans have impacted the environment, particularly the spread of plastic waste. After watching a short film about the Laysan albatross population, learners complete a worksheet and research other ways that plastic...
