Waves Through Earth: Interactive Online Mac and PC

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.

Sea Floor Spreading I

In this introductory Excel tutorial (Activity I) students use Excel to explore the geodynamics model equation for ocean depth around a sea-floor spreading center. For students with no prior Excel experience.

Sea Floor Spreading II

Students import ocean bathymetry data from text files, they then use Excel to graph these observations along with model prediction to assess the model's ability to simulated the observed topographic features of the North Atlantic.

Human Demographics

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

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.

Conics and Reflection

This is a discovery bases lesson on the reflective properties of the conics: parabolas, ellipses, and hyperbolas.

Chemical Equilibrium Misconceptions

This STELLA modeling and writing assignment helps students confront and replace common misconceptions about chemical equilibrium.

Fishing Game: Stella PC and Mac

As manager in the fish and wildlife service you are charged with making policy regarding the management of a regional fishery.

Salmon Smolt: Stella PC and Mac

The Stella Smolts Migration Model focuses on the spring migration of hatchery smolts to the ocean. It may be used to test the relative merits of barging fish or drawing down the reservoirs to help the smolts reach the ocean.

Sun Path: Interactive On-line Mac or PC

Students use SunPath in the yearly mode to investigate seasonal changes in sunrise, sunset, length of day and sun altitude at their own latitude. JAVA activity for Mac or PC.
