Human Demographics part of Mathematics and Statistics Models:Examples
In this biology simulation students explore factors that change human population growth including age at which women begin to bear children, fertility rate and death rate.

Genetic Drift part of Mathematics and Statistics Models:Examples
In this biology simulation, students use a mathematical simulation of genetic drift to answer questions about the factors that influence this evolutionary process. Students run a series of simulations varying allele frequency and population size and then analyze their data and propose a model to explain their results.

Evolution, Natural Selection and Speciation part of Conceptual Models:Examples
In this out of class tutorial, students explore several examples of natural selection and speciation.

Translation simulation part of Conceptual Models:Examples
This module introduces students to the basics behind translation of a messenger RNA sequence into protein. In addition to text and movies, there are interactive shockwave animations that allow students to move ribosomes and tRNAs to perform translation.
