```									                         Exponential Growth and Decay Project

Objective: Students will create and explain a visual representation of exponential growth
or decay.

1. Pick a topic of exponential growth or decay. Feel free to research and come up
with other topics.
Exponential Growth Topics              Exponential Decay Topics
Population                               Medicine Level in Blood
Credit Card Account with interest rate
or Savings Account with interest rate
Value of stock when there is steady set Value of stock when there is

2. Write a 1 page paper to explain the growth/decay of your topic. Give examples of
how this information is used, when it was first discovered, etc.
3. Create a PowerPoint presentation showing the growth/decay for 10 generations or
10 cycles. We looked at this applet to get us started.
