Scientific Notation III: Linear vs Exponential

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...

How can you safely model exponential growth and decay? A hands-on activity uses candies to model not only exponential decay, but also exponential growth. Exponential equations are fitted by hand and by use of a calculator...

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.  

Quiz your middle and high schoolers on solving exponential growth and decay. First, they evaluate for a variable given the second variables value. Then, they graph an equation that illustrates the exponential growth or exponential decay...

Explore exponential growth with this interesting scenario: You can either have $1000 a year for twenty years, or you can get $1 for the first year, $2 for the second, $4 for the third, etc, doubling in amount each year for twenty years....

Show how exponential growth can look linear. Pupils come to understand the importance of looking at the entire picture as they compare the US population to the world population. Initially, the populations look linear with the same rate...

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.

Sal solves several problems involving exponential growth functions for two reasons. First, he aims to familiarize viewers with the process, particularly for those who find exponents challenging or daunting. Second, Sal wants to show how...

When your biology or ecology class is studying populations, show this video to explain the concept of exponential growth. You could also use it with a math class. A nice addition would be to read the children's book, The Rajah's Rice: A...

Examine an exponential growth model. Using a fractal, learners calculate the perimeters of each stage. When comparing the consecutive perimeters, a pattern emerges. They use the pattern to build an equation and make conclusions.
