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

This activity guides the analysis of a published scientific figure from a study that investigated how gene duplication contributed to the evolution of electric fish.

This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.

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 asynchronous course is designed to deepen educators' content knowledge in evolution, especially regarding content appropriate for teaching at the high school level.

This video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

This hands-on activity allows students to analyze DNA sequences of Ebola viruses. Students use these sequences to track the virus’s spread during the 2013–2016 Ebola outbreak in West Africa.

This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.

This interactive module traces the evolutionary history of birds by comparing the bone structures of a chicken to those of other species.

This activity explores an image of early embryonic cells, which serves as a phenomenon for learning about cell division and development.

In this activity, students explore the phenomenon of convergent evolution presented in the short film The Origin of Species: Lizards in an Evolutionary Tree. They build and interpret phylogenetic trees to infer how certain adaptations evolved among the Anole lizard populations of the Caribbean.
