Tonight's homework is to complete Assignment 28 Part 1 and read and take notes "Population: 7 Billion" from the January 2011 issue of National Geographic. Be sure to check out some of the links to pictures as well. If the above link doesn't work then try this or this. If you didn't complete any aspect of the weekend's homework previously, then it is strongly recommended that you do so.

Think about:
- What concerns are associated with humankind's rapid population growth?
- Is our growth occurring equally everywhere on Earth?
- What, if anything, is being done to deal with population growth?

Analysis

Part I: Unrestricted Exponential Growth of the iPhone Island Population

Use your data table to plot a graph demonstrating the unrestricted exponential growth of the population over time. Be sure to give your graph an appropriate title and follow the practices associated with good graphing.

“iPhone Island – Modeling Exponential Growth” Analysis and Thinking Questions

Answer all of the following questions to best of your ability in complete sentences. Use examples, details, and vocabulary to help support your answers.

Part I: Unrestricted Exponential Growth of the iPhone Island Population

1. What is the ratio of births to deaths in this model population?

2. How many “years” did it take you to reach a population of 100?

3. What inferences and/or connections can you make based on the graph of iPhone Island’s population growth?

4. Using this experiment, define exponential (or geometric) growth.

5. In what way do exponential (or geometric) growth rates differ from arithmetic (linear)

growth rates?
