Curated OER
Form and Observation
Use a familiar song and adorable baby animal pictures to teach youngsters about genetic variation. Begin by listening to "Twelve Variations on 'Ah vous dirai-je Maman,'" which you will need to find online (there are several versions...

Color Variation Over Time in Rock Pocket Mouse Populations
While many mutations are neutral, those that appear advantageous increase in frequency in a population. Scholars use illustrations to make predictions about populations of mice. They follow it up with a video to confirm or refute their...

Molecular Genetics of Color Mutations in Rock Pocket Mice
Can you identify mutations just by viewing DNA sequences? Scholars apply prior knowledge of DNA sequences to do just that in an engaging activity. They transcribe and translate genes, thus identifying the locations of mutations. Then,...

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...

Punnett Squares/Genetics
Ninth graders complete a monohybrid cross and a dihybrid cross. In this biology lesson, 9th graders predict the traits of offspring using the Punnett square. They differentiate recessive and dominant genes.

Biodiversity and Evolution – Darwin’s Finches
Teens experience natural selection firsthand (or first beak) in an activity that has them act as finches foraging for food. Using different household items to act as different beak styles, your little finches will collect as much food...

Do You Have the Key?
Students practice using a dichotomous key. For this classification lesson, students read an article about scientific exploration and identification of new species. They use a dichotomous key to identify objects and create their own key.
Curated OER
Gene Action and Mutation
Students review terms related to DNA structure and function. They complete a variety of worksheets in small groups or in pairs reflecting the unit's concepts regarding DNA. They submit their worksheets for grading.
Curated OER
Nature vs. Nurture
Eighth graders investigate the concept of nature versus nurture in human development through this series of lessons.
