In this card activity, students investigate the functions of major digestive organs.

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 build a paper model of DNA and use their model to explore key structural features of the DNA double helix. This activity can be used to complement the short film The Double Helix.

This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.

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.

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.
