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. 

Testosterone Levels in Elite Athletes

This activity guides the analysis of a published scientific figure from a study that compared the testosterone levels of Olympic-level elite athletes.

Why Two Heads?

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

Monkey Social Status and Immune Response

This activity guides the analysis of a published scientific figure from a study on how social status affects the expression of genes involved in immune system processes.

HIV Receptors and Co-receptors

This demonstration models the first step of the HIV life cycle: the binding of HIV envelope proteins to receptors on human helper T cells.

Synchronized Division

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

Sizing up the Brain Gene by Gene

In this talk, biomedical scientist Christopher Walsh discusses how DNA sequencing technology has led to a better understanding of the genes involved in brain development.

From Cancer Genomics to Cancer Drugs

In this talk, biomedical scientist Charles Sawyers discusses how genetic data reveal common mutations in cancer and can help uncover shared genetic mechanisms among different cancer types.

Investigating Planarian Behavior and Regeneration

This activity allows students to observe their own planarian and then design an experiment to investigate how planarians regenerate. It supports viewing of the video Identifying Key Genes in Regeneration.
