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.

Sea Floor Spreading I part of Examples
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.

Subject: Geoscience:Geology, Oceanography

Sea Floor Spreading II part of Examples
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.

Subject: Geoscience:Geology, Oceanography

World Population Activity II: Excel part of Examples
(Activity 2 of 2)In this intermediate Excel tutorial students import UNEP World population data/projections, graph this data, and then compare it to the mathematical model of logistic growth.

Subject: Environmental Science:Human Population, Mathematics:Statistics

World Population Activity I: Excel part of Examples
(Activity 1 of 2) This activity is primarily intended as an introductory tutorial on using Excel. Students use Excel to explore population dynamics using the Logistic equation for (S-shaped) population growth.

Subject: Environmental Science:Human Population, Mathematics:Statistics

Wind Surge: Interactive On-line Mac and PC part of Examples
Wind surge is a JAVA based applet for exploring how water level on the windward and leeward side of a basin depends on wind speed, basin length, water depth, and boundary type.

Medicine in the Body part of Pedagogy in Action:Library:Teaching with Spreadsheets:Examples
In this activity, we will explore how the dosage and frequency of a medicine taken affect the amount of medicine present in the blood.

Subject: Mathematics

Fishing Game: Stella PC and Mac part of Examples
As manager in the fish and wildlife service you are charged with making policy regarding the management of a regional fishery.
