  • Product Description
  • StandardsNEW

Students will be introduced to the idea of Natural Selection and basic ecology. Understanding the intricate relationship between genes, the environment, and change that could occur over time is the focus of this article. Investigative questions about antibiotic resistance, depleting cheetah populations, and a brief history of Darwin's observations allow students to apply the idea of natural selection to current populations. Intended to cover the Tennessee Science Standards 8. LS4.3 and 8.LS4.4, this article can also be used for NGSS standards or any other academic standards that are similar.

NGSSMS-LS4-6
Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time. Emphasis is on using mathematical models, probability statements, and proportional reasoning to support explanations of trends in changes to populations over time. Assessment does not include Hardy Weinberg calculations.
NGSSMS-LS4-4
Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment. Emphasis is on using simple probability statements and proportional reasoning to construct explanations.
