Natural Selection and Evolution of Rock Pocket Mouse Populations
Can evolution repeat itself? Scholars analyze amino acid data in two separate populations of mice. They learn that evolution repeats itself, but natural selection prefers some mutations over others in different environments. Analysis...

Population Genetics
Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...

Zebrafish and Skin Color
You may not know if that zebrafish in your fish tank is a model citizen—but it is definitely a model organism! What can we learn about ourselves from a tiny zebrafish? Discover more about the polygenic trait of skin color through a...
Curated OER
Speciation and Genetic Drift Worksheet
Fifteen terms pertaining to speciation, extinction, and gene flow are to be matched to their definitions. This simple, easy-to-read worksheet can be used as a pop quiz for your biology learners when studying natural selection principles...
Curated OER
Genes within Populations
Finally, here is a genetics worksheet that does not include Punnett squares! Designed for a more advanced class, biology learners will compare Lamarck's concept of evolution with Darwin's. They will explore the Hardy-Weinberg equilibrium...
Curated OER
Evolution Study Guide
Thirty short-answer questions comprise this detailed review of evolution theory. Many of the questions ask scholars to define vocabulary. Because short answers are required, this worksheet will take some time to complete. You could give...
Curated OER
Hardy-Weinberg Lab Data
The ten slides give multiple examples of Genetic Drift, or cases of particular genetic populations. Each set of data requires an explanation and the allele frequency changes should be easy for your students to calculate.
Curated OER
Genetic Drift
Students use a mathematical simulation of genetic drift to answer questions about the factors that influence this evolutionary process. They run a series of simulations varying allele frequency and population size and then analyze their...
Curated OER
Stack #84201 Word Search
In this science worksheet, students locate and identify various vocabulary terms related to biology. There are fifteen words located in the puzzle to find.
Curated OER
Natural Selection Foldable
Young scholars examine and identify examples of species that developed as a result of immigration, genetic drift, and adaptive radiation. They conduct Internet research and define key vocabulary terms, and use their species example on...
