This activity supports the film Popped Secret: The Mysterious Origin of Corn. Students analyze data on the expression of the tb1 gene to explain how variations in this gene played a role in the evolution of corn.
In this activity, students extend the concepts covered in the short film The Biology of Skin Color through the application of models and mathematical thinking to explain how genomic variation and human ancestry can explain differences in skin color, a polygenic trait.
In this activity, students further explore the short film Popped Secret: The Mysterious Origin of Corn, by working through the mathematical concepts behind George Beadle’s claim that teosinte is the wild ancestor of maize.
In this hands-on activity, students analyze the results of genetic crosses between stickleback fish with different traits. It complements the film Evolving Switches, Evolving Bodies.
This activity reinforces concepts of variation and natural selection covered in the short film Natural Selection and Adaptation. Students apply the Hardy-Weinberg equation to real data collected on rock pocket mouse populations.
This interactive, modular lab explores how stickleback fish and fossil specimens are used to study evolutionary processes, with an emphasis on data collection and analysis.
