Candy Dish Selection

This editable worksheet is set up so that biology pupils read four case studies and identify points that are present in each, such as overproduction, heritable variation, struggle to survive, and differential reproduction. They also...

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...

Adaptation or acclimation? Young ecologists determine which is being exemplified in twenty questions. When teaching about adaptations, make sure to talk about acclimation, a short-term learned response to a change in the surroundings....

The peppered moth is featured in a video about natural selection. The narrator tells the story of Darwin's theory and then moves on to the principles behind natural selection and the different ways it works. Concepts covered include...

Selective breeding has resulted in some novel and beautiful or useful dogs over the years. Using the American Foxhound as an example, genetics learners find out how and why they came about. Then, in small groups, they select breeds to...

The pocket mouse can be light brown like the sands of the desert, or dark brown like the volcanic lava flows that are interspersed throughout New Mexico's Valley of Fire. It seems that predators have weeded out light colored mice in this...

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...

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...

Between 1968 and 2002, the total number of peppered moths decreased by almost two thirds, although scientists do now know why. In the 10th video of the series, the instructor defines evolution as any changes to a gene pool. Scholars then...

It's not every day that you end up rooting for a mouse. A breathtaking video takes scholars to the American Southwest to learn about the rock pocket mouse. It describes how mice with black fur had an evolutionary advantage in the dark...
