Population Growth – Exponential and Logistic Models vs. Complex Reality
This analysis and discussion activity is designed to help students develop a solid understanding of the exponential and logistic models of population growth, including the biological processes that result in exponential or logistic population growth. Students learn about the simplifying assumptions built into the exponential and logistic models and explore how deviations from these assumptions can result in discrepancies between the predictions of these models and the actual trends in population size for natural populations. This activity is designed to help students meet the Next Generation Science Standards and the Common Core State Standards.
The first two attached files have the version of the Student Handout that engages students in understanding the mathematical formulae for the exponential and logistic models of population growth, as well as evaluating the relative advantages of graphs and mathematical formulae as models of population growth (first file is a Word document and second file is a PDF). The third attached file has the version of the Student Handout that omits the mathematical formulae. The fourth attached file has the Teacher Notes for this activity.
