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...

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...

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...

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.

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.
