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...

Natural Selection and the Evolution of Darwin's Finches
Darwin explained the connection between species of finches 150 years before scientists understood DNA. Technology and progressing science proved he was right, yet many struggle to understand how natural selection happens. Scholars use...

Population Genetics
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...

What Do You Know About Genetics?
Just what do you know about genetics? The online resource contains 10 questions about genetics. Scholars work through the questions ranging from what DNA stands for to how much of human DNA is similar to that of a fruit fly. Scholars...

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...

A Nature and Nurture Walk in Mendel Park
We are what we make of ourselves ... sometimes. Learners play a game to come up with the answer to a riddle. The game consists of determining whether different scenarios are due to nature or nature and nurture. With each correct answer,...

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
High schoolers 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.

Mendelian Genetics, Probability, Pedigree, and Chi-Square Statistics
People with the sickle cell trait, but not sickle cell disease, find natural protection against malaria. Scholars consider various combinations of genotypes and environmental factors to determine if children might have sickle cell...

Population Genetics, Selection, and Evolution
The Hardy-Weinberg principle states that alleles and genotypes remain constant in the absence of evolutionary influences. Scholars complete a simple hands-on activity applying the Hardy-Weinberg principle to sample data. They observe how...

Natural Selection and Evolution of Rock Pocket Mouse Populations
Can evolution repeat itself? Scholars analyze amino acid data in two separate populations of mice. They learn that evolution repeats itself, but natural selection prefers some mutations over others in different environments. Analysis...

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...

Nature or Nurture Quiz
Eighteen questions ask pupils whether certain behavior or trait is based on nature or nurture. Scholars take a quiz, reflect on their answers, then challenge a friend or family member to complete it.
