Exponential/Logistic Growth and Decay Project

Objective: Students will create, use and explain a visual representation of exponential growth/decay or logistic growth and predict future events for the scenario.

  1. Pick a topic of exponential growth/decay or logistic growth. Feel free to research and come up with other topics.

Exponential Growth Topics / Exponential Decay Topics / Logistic Growth Topics
Yeast, bacteria / Radioactive Elements / Spread of a disease
Population / Medicine Level in Blood / Spread of a rumor
Credit Card Account with interest rate or Savings Account with interest rate / Change in value of a car or computer over a period of time / Popularity of iPhone app/game
Value of stock when there is steady set increase / Value of stock when there is steady set decrease / Fads (like the Harlem Shake)
  1. Write at least one paragraph to explain the growth/decay of your topic. Give examples of how this information is used, when it was first discovered, etc.
  2. Create the Growth or Decay model for your topic. Once a model is decided upon, use it to predict two future events – one in the near future, and one in the distant future.
  3. Graph your model with a decent degree of accuracy.
  4. Gather all pieces of this assignment and display them neatly on a poster or powerpoint.
  5. This project will be due Thursday, April 27th! It will count as a 30 point assignment.
