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...
Curated OER
Genes within Populations
Finally, here is a genetics activity 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...

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...

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.

AP: Chapter 23: The Evolution of Populations
How and why do populations change over time? AP biology aces explore this question by completing this assignment. They write the answers to 21 questions regarding population genetics, stability, genetic drift, polymorphism, and selection.

How Does Evolution Work?
Students investigate how natural selection influences evolution. They complete a hands-on lab simulation of natural selection, and replicate a real experiment and examine the interplay between selection factors in a population of guppies.

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...
Curated OER
Natural Selection Foldable
Pupils 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 their...

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
Diversity/Natural Selection
High schoolers examine mechanisms behind biological evolution and the theories that feed it, and are able to demonstrate their knowledge of these theories in a story.
Curated OER
Mechanisms of Evolution
In this evolution worksheet, students will answer questions about population genetics and the theory of evolution of species. This worksheet has 15 true or false, 6 fill in the blank, and 4 short answer questions.

Introduction To Natural Selection
Seventh graders investigate the concept of natural selection and it relation to the theory of evolution. They create a definition for classification based upon looking at other subjects that are similar. The variation of species is...
