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

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. 

This video case study explores whether fungicides play a role in the decline of bee populations.

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

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

This activity allows students to formulate and analyze scientific questions.

This interactive module allows students and educators to document, annotate, and reflect upon scientific research processes.

This interactive module consists of a virtual Winogradsky column, which can be used to explore the diversity of microbes, microbial metabolic strategies, and geochemical gradients found in sediments.

This activity guides the analysis of a published scientific figure from a study that investigated demographic patterns in Ebola outbreaks from the Democratic Republic of the Congo.

This animation shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.

This interactive module explores how CRISPR-Cas9 technology works and the many ways in which scientists are using it in their research.
