The Making of the Fittest: Natural Selection and Adaptation
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...

Color Vision Genetics Evolution Simulation
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 Effect of Natural Selection on Genes, Traits and Individuals
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...

The Making of the Fittest: Evolving Switches, Evolving Bodies
How did the stickleback fish, which was once ocean bound, evolve to be able to persist in freshwater lakes? Hear from the scientists who identified the genes and related switches that allowed these survivors to adapt. In addition to the...

Natural Selection Day 1
Young scholars define the concept of classification. In groups, they categorize a series of objects into categories they identify. As a class, they participate in a variety of activities to examine the concept of natural selection. To...

The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture
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...

The Making of the Fittest: The Birth and Death of Genes
Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Comparing Theories: Lamarck and Darwin
Students compare the evolution theories of Lamarck and Darwin. They use self-assessment and a video to increase their knowledge of evolution theories. They research questions and present them to the class.

Genetics
Comprehend that many human characteristics-all physical traits and possibly many personality traits-are determined by our genetic makeup. These activities demonstate that all physical traits are genetically determined, some evidence...

Understanding Genetics: Punnett Squares
Can scientists really predict genetic outcomes or are they simply making a lucky guess? Scholars first learn about Gregor Mendel and how to make Punnett squares. Then they extract DNA from a strawberry in a lab with included conclusion...

Allele and Phenotype Frequencies in Rock Pocket Mouse Populations
In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...

Natural Selection
Kids act as scientists and preditors in this short natural selection activity; they collect and analyze data, then apply their new knowledge to real-world examples of natural selection. The layout of the worksheet is easy enough to use...

Evolution of Fur Color in Mice – Mutation, Environment and Natural Selection
Most species of animals include a variety of fur or hair color, but why? Scholars watch a video about a changing environment for mice. As the rocks around them change hues, different colors of mice begin to thrive. Discussion questions...

Artificially Selecting Dogs
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...
