Exponential Models

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...

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.

Playing with matches (unlit, of course) becomes an engaging learning experience in this fun instructional unit. Teach pupils how to apply properties of exponential functions to solve problems. They differentiate between quadratic and...

Young scholars 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.

High schoolers 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.

This instructional activity unit guides students in developing strategies for modeling problems. The task focuses on investigating a cat shelter's claims about the rate of cat population growth. The unit includes a full lesson plan,...

In this human population changes in survival worksheet, students interpret and plot data to understand the differences in human mortality and survivorship between historic and modern times. They investigate how these changes influence...

Pupils determine the average annual rate of change (growth rate) of U.S. national population for each decade of historical census data.

Essay on population growth past, present and future and the impact on society. Includes guiding questions for students and links to related resources.

Young scholars examine the impact that population growth has on world resources.
