Waves Through Earth: Interactive Online Mac and PC part of Examples

Students vary the seismic P and S wave velocity through each of four concentric regions of Earth and match "data" for travel times vs. angular distance around Earth's surface from the source to detector.

Genetic Drift part of 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.

Human Demographics part of 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.
