Reebops: A “Model” Organism for Teaching Genetic Concepts
6th - 12th
In a sweet simulation, junior geneticists examine the chromosomes of a fictitious Reebop marshmallow animal, combine chromosomes to produce offspring, and then make a model of the resulting Reebop baby. Phenotypes include number of...
The Effect of Natural Selection on Genes, Traits and Individuals
9th - 12th CCSS: Designed
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...
Allele and Phenotype Frequencies in Rock Pocket Mouse Populations
9th - 12th CCSS: Designed
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...
Punnett Squares with Piebald Deer
5th - 10th CCSS: Adaptable
Explore the science behind Earth's amazing diversity of life with this lesson on genetics. Looking at specific traits in piebald deer, carnations, and roan cattle, young scientists use Punnett squares to determine the possible genotypes...
Why Are Some People Left-Handed?
