The 'A Civil Action' 1-D Contaminant Transport Game is an EXCEL spreadsheet that enables students to compute concentrations of TCE traveling in the groundwater flow system toward well H that emanate from the W.R. Grace site. The idea of the game is to draw students into learning some of the fundamental concepts about (1) how contaminants move in the subsurface and (2) how models can be used to test hypotheses. These concepts are taught within the context of the famous 'A Civil Action' trial described in the book by Jonathan Harr (1996) and the movie starring John Travolta (1998).
The spreadsheet computes values of hydraulic head, advective flow velocities and traveltimes, contaminant velocities, and contaminant concentrations at 20 locations along the flowpath from W.R. Grace to the Aberjona River. Breakthrough curves showing changes in concentration versus distance and changes in concentration versus time pop-up automatically (see below). The spreadsheet also creates graphs of advective and contaminant velocities versus distance.

This Western Mining History database uses Mineral Resources Data System to list known Colorado historical mines by county. Each county site has links to the known mines within its borders. Some are known and named, others are unnamed. Mines should be assumed to be on private property unless other research is conducted. Data provided for each mine site include: Name, State, County, Elevation, Primary Mineral Mined, Latitude and Longitude and a link to Google Maps. Photos are provided where available. Additional information for some Mines are satellite photos, and ownership, business and historical records. Mining History is an historical site that provides information on mining, mining towns, the gold and silver rush, and Photos and maps of the western United States. This is a great database for student historical research or data and statistics classes. Consider becoming a member or making a donation to help further the work of the site.

This activity is designed to help students visualize and explain the relationships between various terms and concepts related to the science of climate change. After performing this activity students will (hopefully) be able to define various climate change terms and explain the process of climate change.

This unit introduces high school students to climate change, the carbon cycle, and the effects of increasing atmospheric carbon dioxide on Earth's climate. Students create a model from string, toss bean bags, and sort chemical cards to review key processes in the carbon cycle. Then they quantitatively model the carbon cycle by playing a board game.

Polymers are a vital part of our everyday lives and nearly all consumer products have a plastic component of some variation. Students explore the basic characteristics of polymers through the introduction of two polymer categories: thermoplastics and thermosets. During teacher demos, students observe the unique behaviors of thermoplastics. The fundamentals of thermoset polymers are discussed, preparing them to conduct the associated activity in which they create their own thermoset materials and mechanically test them. At the conclusion of this lesson-activity pair, students understand the basics of thermoplastics and thermosets, which may entice their interest in polymer engineering.

Based on the 2010 Scientific American paper by Hazen, and the more technical 2008 paper of Hazen et al, both of which explore the effect of the biosphere on the tremendous number of mineral species that occur on Earth compared to the lesser number we believe we are seeing on other planets. This tackles the idea of mineralogy/geochemistry evolving over time as do biological systems, rather than being a static system with no hysteresis or temporal aspect to it. Students work in small groups to decide which groups of minerals have been most affected by a variety of biological influences, and how. Then the class as a whole compares their conclusions group by group.
