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...

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...

Some species have one gender that is r-selected while the other is K-selected.  A video focuses on growth rate and the difference between r-selected species and K-selected species. It includes a discussion of fecundity and carrying...

Touchdown! This is an exponentially insightful lesson that explores the growth of football games with different video game consoles. Class members discuss whether the increase of mergahertz can be described as linear or exponential. The...

Start with the basics and move up the exponential ladder to master a variety of problem-solving and application problems. The problems are heavy on exponential growth and decay, compound interest, and natural log.  

How do you make a penny grow to $5,000 in just 15 days? Use the examples in this lesson to explore the concept of exponential growth and its comparison to linear models. Pupils come to understand that exponential growth eventually...

Concepts from the last few videos, particularly exponential growth and decay functions, are covered in this video about word problems. Viewers can apply their new (or growing) algebraic knowledge to solve the word problems along with Sal.

A real-world scenario of how a rumor might spread in school is used to demonstrate an exponential growth pattern.  The class will have to use reasoning skills and communicate with each other to problem solve and come up with some...

In this 2-day instructional activity focused on exponents, middle schoolers will cross the curriculum by engaging in science, history and language arts activities. Exponential growth will be explored using grains of rice on a chess...

Transitioning between algebra and geometry is no problem for Sal as he deftly solves these practice SAT problems. Mathematicians who have a hard time moving between skill sets will appreciate the way that Sal addresses each new problem...

Here's everything one ever wanted to know about exponential growth and decay in one thorough lesson. A video lesson presents the basics of exponential growth and decay and then applies the information to word problems. The lesson wraps...

Take a break from learning new information and take time to review. Scholars review the unit by completing some practice problems. They rewrite expressions using exponents, solve exponential equations, graph exponential functions,...

Change the way the class looks at percent change. Scholars learn to write exponential functions from given information about percent change and to solve real-world problems involving the concept. They also see how to identify the initial...

Differentiate everyone's knowledge. Pupils work through nine review questions to highlight key concepts from Unit 7. Items range from finding slope fields and reasoning with them to finding general and particular solutions of...
