Searching for exciting lesson plans filled with hands-on activities to use in your traditional classroom environment? Look no further! This set of lesson plans for AP Biology covers topics from genetics to evolution, botany to ecology,...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Engage young biologists with four laboratory activities that explore the fossil record. Learners examine fossil images, a fossil kit, the rock record, and geologic time scale. They even experiment with the oxygen production of an Elodea...

The first examples of mimicry we have found date back to before flowering plants. The video goes in depth on predators at the community ecology level. It includes discussions of herbivores, parasitism, adaptations, cryptic coloration,...

Humans share about 50% of their genes with a banana. In the video, scholars analyze the scientific evidence for evolution. The instructor spends time discussing Darwin and biogeography, fossils, and homologous structures. Scholars then...

Some scientists believe humans are no longer evolving and have reached their evolutionary peak. In the video, scholars explore Darwin and his published work, The Origin of Species. The instructor discusses Darwin's ideas of biogeography,...

About 70 percent of the genes of the stickleback fish are the same as humans. In the video, scholars further explore the stickleback fish and its history, from being removed from Loberg Lake to their change and comeback. Over time, these...

How does something remain the same in order to change? The video discusses homeostatic evolution from both the continuity and changing perspectives. An analysis of the excretory system in flatworms, earthworms, and vertebrates shows...

Viewers explore real-world examples of both evolution and natural selection as the instructor discusses changes to the environment, mutations causing changes in phenotypes and changing the fitness in organisms, and how humans are...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...
