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

In this inquiry-based activity, students engage in science practices to figure out why some people with a genetic condition that usually leads to sickle cell disease do not have disease symptoms.
 

In this activity, students explore using CRISPR-Cas9 to knock out butterfly genes in order to determine their function.

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.

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

In this hands-on activity, students review the steps of eukaryotic gene expression and learn how this knowledge can be used to treat different genetic conditions. The activity reinforces concepts covered in the Click & Learn “Central Dogma and Genetic Medicine.”

This activity guides the analysis of a published scientific figure from a study on how social status affects the expression of genes involved in immune system processes.

This activity explores the content presented in the animated video How Tube Worms Survive at Hydrothermal Vents, which tells the story of the symbiotic relationship between the giant tube worm and chemosynthetic bacteria.

This activity analyzes a published scientific figure from a study assessing if the microbiota from a mother affects the immune systems of the developing offspring.

In this activity, students use cards to build model food webs and evaluate how ecological disturbances affect each trophic level using information from the citizen science website WildCam Darién.

This activity complements the animated short video Seeing the Invisible. Students explore concepts related to relative size and scale using cards of cells and microorganisms.
