Modeling the Structure of DNA

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.

Patterns of Predation

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

Serengeti: Nature’s Living Laboratory

This film explores the foundational research in the Serengeti National Park, Tanzania, that uncovered many of the ecological principles that govern how animal populations and communities are regulated.

White-Nose Syndrome

This activity explores images of bats with an infectious fungal disease, which serve as phenomena for learning about population dynamics and disease impacts.

Developing an Explanation for Tuskless Elephants

This activity builds on information presented in the video Selection for Tuskless Elephants. Students use scientific evidence and reasoning to construct an explanation of and develop an argument for tusklessness in elephant populations.

The Wolves of Isle Royale

This activity explores images of wolves hunting a moose on Isle Royale, which serve as phenomena for learning about predator-prey population dynamics.

Serengeti Wildebeest Population Regulation

This activity analyzes a published scientific figure from a study in Serengeti National Park, Tanzania. In this study, scientists investigated how the eradication of rinderpest disease led to a boom in the wildebeest population.

Pelvic Evolution in Sticklebacks

This activity guides the analysis of a published scientific figure from a study that used SNP genotyping to identify the mutations that result in morphological differences in stickleback fish.

Using Images as Phenomena

This hands-on activity engages students in asking questions about phenomena using collections of images.
