The Power of Exponentials in Daily Life

Watch the Blossoms video called “the power of exponentials”: 


How would you explain the idea of exponentials growth and decay in daily life? Think of creative ideas to model the math concept.


Students can present a picture or a video that shows exponentials in daily life and describe the variables and the equation connected to it. 

Example---How fast does a secret spread 

If it takes a person 1 minute to tell the secret to 2 others (that have not been told the secret before), how long will it take for the secret to be told to 100 persons? 1000 persons? Or even to your country? 

We are looking forward to your ideas!
