Evolution 101: Labs for Advanced High School Classes

This collection is designed for Advanced Evolution and for the evolution section of Advanced Biology courses. It includes three EvoBeaker® labs that are widely used in college Evolution and Introductory/Non-Majors Biology courses.

The laboratories in our Evolution 101 package are also included in our Complete 101 Collection. If you or your colleagues also teach Advanced Biology, the school-wide Complete 101 Collection is a great choice!

Evolution 101 Labs

EvoBeaker: Darwinian Snails

This popular lab examines the assumptions behind natural selection using an engaging interactive simulation of green crabs preying on periwinkle snails. Students are able to "violate" each assumption in turn to explore whether evolution by natural selection still occurs. Exercises are targeted to address common misconceptions among biology students.

EvoBeaker: Sickle-Cell Alleles

An interactive simulation of the classic malaria and sickle-cell anemia system is used to explore natural selection and genetic drift. Students examine African villages with different malaria death rates. First they use the Hardy-Weinberg equation to calculate the expected proportion of sickle-cell carriers from HbS and HbA allele frequencies. Then they examine how the allele frequencies change with changes in malaria risk and with different "founder" scenarios. Finally they explore genetic drift without selection by looking at different-sized villages where both diseases have been cured. An optional advanced section allows independent exploration of evolutionary forces using a basic population genetics model with adjustable parameters for selection strength, immigration rate, and population size. This is one of our most popular labs for introductory biology college courses.

EvoBeaker: Evolutionary Evidence

Evolutionary Evidence offers a powerful and fun way for students to explore how “descent with modification” produces nested patterns of shared traits, which generates testable hypotheses about the fossil record. Importantly, students see how trait patterns differ between evolved species and those generated by “intelligent designers”. This lab is a great set-up for learning how to interpret and construct evolutionary trees.

"[I like] the way [the Snail lab] walks the students through the requirement for natural selection one by one, and shows what happens if each of the requirements isn't met. I also like that it has students working with real data."
