World Population Activity I: Excel

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...

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...

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...

In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...

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 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...

Some scientists believe the earth is already over its carrying capacity for humans. The video explains what a carrying capacity is and the limiting factors to consider. It also teaches how to calculate growth rate, interpreting growth...

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...

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...

Young scholars import UNEP World population data/projections from either the World Population Prospects: The 2002 Revision Population Database - UN Population Division or a text file. They graph this data by itself, and then along with...
