In this activity, students investigate the phenomenon of lactase persistence by making sense of a series of data sets.

In this hands-on activity, students build a paper model to explore how CRISPR-Cas9 is used to edit genes.

This activity guides the analysis of a published scientific figure from a study that investigated whether there is a correlation between a population’s diet and copies of a certain gene.

This activity analyzes a figure showing the atmospheric carbon dioxide concentration from 1958 to 2023.

This activity guides students through building a conceptual model of how carbon dioxide affects Earth’s climate.

This activity extends concepts covered in the film Got Lactase? The Co-evolution of Genes and Culture. Students infer whether someone is likely to be lactase persistent or nonpersistent based on the data from two different tests.

In this activity, students simulate a lactose tolerance test, similar to the one shown in the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, to determine which samples contain the lactase enzyme.
