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...

Does where we live influence how our bodies express genetic traits? Explore variation in human skin color with an activity that incorporate video and hands-on learning. Individuals model the relationship between phenotypes and genotypes,...

Why are so many inherited diseases more prevalent in populations of specified races? Scholars learn about pedigrees and genetics using a reading, an animation, primary sourced letters, a short video, a biography, a guided practice...

What's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...

The most popular AP science exam, Biology, also maintains the highest passing rate. The College Board releases old test questions covering trichomes and much more, along with statistics and scoring guidelines to help scholars study for...

How quickly do animals evolve? Can comparing different samples of the same fossil answer timeline questions? Scholars use virtual labs to examine fossils and learn about stickleback evolution. They compare pelvic morphology in lakes...

[Free Registration/Login may be required to access all resource tools.] Introduction to macroevolution, microevolution, and population genetics.

This lesson plan focuses on differences in the amino acid sequence of hemoglobin and myoglobin proteins. They use the number of differences to create a phylogenetic tree.

A team of scientists studied the schooling behavior of threespine stickleback fish by experimentally testing how individual fish responded to an artificial fish school model.

Students discover that variation in plants allows some varieties to survive in near-drought conditions. Next, students learn that different types of rabbits prefer to eat different varieties of plants. Students make the connection...
