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.

In this activity, students engage with an example from the Serengeti ecosystem to illustrate the exchange of nutrients between plants, animals, and the environment.

This activity explores images of anole lizards subjected to strong winds, which serve as phenomena for learning about natural selection and the impacts of extreme climate events.

This activity guides the analysis of a published scientific figure from a study that investigated how anole lizards may adapt to extremely cold temperatures.

This activity explores an image of tumor cells invading muscle tissue, which serves as a phenomenon for learning about cancer, mutations, and cell division.

This activity analyzes a published scientific figure from a study that investigated the role of p53 in cell cycle regulation.

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 explores an image of early embryonic cells, which serves as a phenomenon for learning about cell division and development.

These two hands-on activities engage students in exploring the genetic basis of cancer using cards and posters.

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.
