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.

Nutrient Cycling in the Serengeti

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

Lizards in Hurricanes

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.

Lizards in the Cold

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

Photosynthesis

This multipart animation series explores the process of photosynthesis and the structures that carry it out.

White-Nose Syndrome in Bat Populations

This activity guides the analysis of a published scientific figure from a study that modeled the impact of an infectious fungal disease on a bat population.

Understanding Global Change

This interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.

Cancer Cell Invasion

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

Exploring Biomass Pyramids
