This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.
This data-driven activity accompanies the video Selection for Tuskless Elephants. It engages students in analyzing data to make evidence-based claims about the occurrence of tusklessness in elephant populations.
In this activity, students collect and analyze evidence for each of the major conditions for evolution by natural selection to develop an explanation for how populations change over time.
This activity extends concepts covered in the film Got Lactase? The Co-Evolution of Genes and Culture. Students analyze data from the scientific literature to draw conclusions about the geographic distribution of lactase persistence.
These interactive questions are integrated with the short film The Making of the Fittest: Natural Selection and Adaptation, which uses the rock pocket mouse as a living example of natural selection.
In this activity, students apply concepts pertaining to the genetics of sickle cell disease and its relationship to malaria explored in the short film The Making of the Fittest: Natural Selection in Humans.
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 explores physical and genetic evolutionary changes in rock pocket mouse populations, as discussed in the short film The Making of the Fittest: Natural Selection and Adaptation.
This activity allows students to collect and analyze data on the evolution of coat color in rock pocket mouse populations living on differently colored substrates.
