Lionfish Invasion: Density-Dependent Population Dynamics

In this Click & Learn, students explore mathematical models that describe how populations change over time and apply these models to the invasive lionfish population in the Bahamas. They also use data from other species to learn how density-dependent factors limit population size.

Exploring Biomass Pyramids

This interactive module allows students to collect and analyze data from a virtual river to construct biomass and energy pyramids.

Population Dynamics

This interactive simulation allows students to explore two classic mathematical models that describe how populations change over time: the exponential and logistic growth models.

Exploring Trophic Cascades

This interactive module explores examples of how changes in one species can affect species at other trophic levels and ultimately the entire ecosystem.

Virus Explorer

This interactive module explores the diversity of viruses based on structure, genome type, host range, transmission mechanism, replication cycles, and vaccine availability.

Survey Methods

This interactive module explores methods used to survey large animal populations, and what they have revealed about the current state of the African elephant population.

Interactive Assessment for The Day the Mesozoic Died

Several questions are embedded within the short film The Day the Mesozoic Died, which tells the story of the scientific quest to explain one of the greatest, long-standing scientific mysteries: the sudden disappearance of the dinosaurs at the end of the Cretaceous period.

The Eukaryotic Cell Cycle and Cancer

This interactive module explores the phases, checkpoints, and protein regulators of the cell cycle. The module also shows how mutations in genes that encode cell cycle regulators can lead to the development of cancer.

Gorongosa Timeline

This interactive timeline explores the history of Gorongosa National Park in Mozambique.

Exploring Transitional Fossils

This interactive module allows students to examine fossils of fish, tetrapods (four-limbed animals), and their transitional forms.

Dengue Virus

This model shows the structure of dengue virus, which causes dengue fever.
