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.

How Animals Use Sound to Communicate

This interactive module explores how different animals — elephants, birds, and bats — have evolved distinct ways of using sound to communicate.

Sampling and Normal Distribution

This interactive simulation allows students to graph and analyze sample distributions taken from a normally distributed population.

Vertebrate Circulatorium

This interactive module explores the circulatory systems of major vertebrate groups to gain insights into their evolution.

BCR-ABL: Protein Structure and Function

This tutorial describes the structure and function of the cancer-causing protein BCR-ABL. It also shows how drugs targeting this protein can help treat chronic myeloid leukemia (CML), a cancer of the white blood cells.

Lizard Evolution Virtual Lab

This interactive, modular lab explores the evolution of the anole lizards in the Caribbean through data collection and analysis.

Gleevec-Resistant BCR-ABL

This model shows a mutated form of the cancer-causing protein BCR-ABL that is resistant to the drug Gleevec.

BCR-ABL

This model shows the structure of the protein BCR-ABL, which causes a type of cancer called chronic myeloid leukemia.

Adenosine Triphosphate (ATP)

This model shows the structure of ATP, a molecule that provides energy for cellular processes, including protein phosphorylation.

Sorting Finch Species

This interactive module allows students to explore concepts related to speciation by identifying which birds belong to one of two finch species.
