This video follows biologist Shane Campbell-Staton, who is studying the adaptations that allow deer mice living at high elevations to stay warm and active during the winter.

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

In this activity, students analyze aspects of a scientific paper that investigates genes involved in the colors and patterns of butterfly wings.

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

This video case study explores the approaches scientists used to identify a mutation that causes retinitis pigmentosa (RP), a progressive disease that leads to blindness.

This activity explores an image of a wildebeest herd on the Serengeti, which serves as a phenomenon for learning about population dynamics and wildlife management.

This video case study explores whether elephants can detect, interpret, and respond to signals delivered by underground vibrations.

This activity guides the analysis of a published scientific figure from a study that explored the evolutionary origins of parasitic beetles that mimic army ants.

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 guides the analysis of a published scientific figure from a study that investigated how herbivore populations are regulated in the Serengeti.

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.
