P_{t (population at time t) }= P_{o}_{( initial population)}e^{r t (growth rate x time)}
Project the world population in 2017 given the 1997 mid-year population of 5.85 billion and a growth rate of 1.36% per year.
N = N_{0} (e)^{kt}N = (5.85 x 10^{9}) x e^{(0.0136 x 20)}N = 7.679 x 10^{9} The population in 2017 will be 7.679 billion.
Mexico growth rate: 1.13%; population 111,211,789
Spain growth rate: 0.072%; population is 40,525,002
A basic rubric is attached, based on students completing both the worksheet and the presentation. However, teachers may choose to make the worksheet due earlier since it is much shorter than the assignment.
Credits: H. Hall for teaching me about population dynamics and allowing me to present this lesson for the first time.
