Sickle cell disease only occurs when both parents contribute the trait, and mostly in those of African descent. Where did it come from? How did it evolve? Tony Allison, a molecular biologist, noticed a connection between sickle cell and...

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...

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

Bring together a study of two major scientific topics with a lesson on the relationship between pollution and evolution. With the help of a PowerPoint presentation, hands-on activity. and class demonstration young scientists learn...

What adaptations exist in order for icefish to survive the subfreezing temperatures of the Antarctic Ocean? Middle and high schoolers can find out through watching a related 13-minute video and performing a simple investigation to...

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

The second lesson in the series begins with a starter activity discussing wild versus domesticated animals. Then, scholars play a card game, with optional variations, to emphasize artificial selection. Next, they attend a field trip to a...

After watching an engaging 13-minute video about the colorless blood of icefish, future ichthyologists examine icefish blood and non-icefish blood (blood samples are simulated with Karo syrup mixtures) to determine advantages of...

In a fun and interactive two-day lesson, learners sort anole lizard pictures by appearance. Next, they watch a video about the anoles and re-sort based on the information in the video. In addition to physical characteristics, budding...

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...

Whether or not you think mice are nice, you'll love the colorful activity! Scholars examine evidence for evolution in the rock pocket mouse through video, discussion, and collaborative work. Learners watch a video regarding variation in...

What does it take to create a scientific theory? Learners attempt to answer the question by studying the work of Charles Darwin and Alfred Russel Wallace. While watching a video, they track observations from each scientist and then look...

One of the most diverse environments on Earth is the ocean. Young scientists explore the living things found in the ocean during an exciting seven-lesson unit. Their study includes organisms from plankton to invertebrates...

Need an a-maize-ing lesson to show your class how regulatory genes work? If you use the well-written resource, they'll be all ears! Biology scholars discover the gene responsible for the evolution of the modern-day corn plant through a...

Introduce ecology classes to biodiversity and interdependence in ecosystems with a PowerPoint presentation. Then, they get up-close and personal with the invertebrate world by collecting insects, classifying them, and graphing their...

What do you call a bee born in May? A maybe! This first instructional activity in a series of four begins with a starter activity to get scholars thinking about the topic. Then a circus, or circuit of seven activities,...
