US Historical Climate: Excel Statistical
Students import US Historical Climate Network mean temperature data into Excel from a station of their choice and use Excel for statistical calculations, graphing, and linear trend estimates.
Vostok Ice Core: Excel (Mac or PC)
Students use Excel to graph and analyze Vostok ice core data (160,000 years of Ice core data from Vostok Station). Data includes ice age, ice depth, carbon dioxide, methane, dust, and deuterium isotope relative abundance.
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.
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.
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.
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.
Trace Gases: Stella II Mac and PC
This Stella model allows students to learn about chemical mass balance in the atmosphere and apply this to atmospheric chlorofluorocarbon and carbon dioxide concentrations.
Wind Surge: Interactive On-line Mac and PC
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.
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.
