This Starting point module is written to assist geoscience faculty who are developing or modifying courses or units on Earth history/historical geology or on contemporary topics that benefit from a historical perspective. It provides information on what this approach is, why it is useful, how to make use of it and includes an annotated list of references and resources. Full description.

This project has students model the geologic timescale using distance as a metaphor for time. Each student writes a summary of a major event or fossil organism. The students then station themselves and their summaries along a path within a gymnasium. Each student's position along the path determines how long ago their organism lived or the event occurred, so students can appreciate the scale of geologic ... Full description.

This site from SERC's Just-in-Time Teaching (JiTT) module presents JiTT warm up questions about the La Brea Tar Pits. The questions introduce the examination of tar formation, animals uncovered in tar pits and possible reasons for their extinction, and features in addition to bones that scientists observe in tar pits. Full description.

This site from SERC's Just-in-Time Teaching (JiTT) module presents JiTT warm up questions about the Cambrian Explosion. The questions examine dating techniques, information used to date the first branch of life, evidence against the Cambrian Explosion, and what is responsible for the huge expansion in size, complexity and body architecture of animals during this age. Full description.

This site from SERC details Just-in-Time Teaching (JiTT) warm up questions. The questions focus on mass extinctions by examining the leading ideas for the cause of the Permian mass extinction along with evidence for and against each idea. Follow up questions are asked about the reasons that tropical rain forest species are becoming extinct so quickly, as well as the differences between deterministic ... Full description.

This site from SERC features Just-in-Time Teaching (JiTT) warm up questions about the ethics of fossil collecting. The site presents questions that examine fossil resource abuse, the issue of fossil hunting on federal land, and collaboration between commercial dealers and scientists. Related resources are provided. Full description.

This resource provides illustrated lecture notes from a geochemistry course offered by Dr. Scott Wood at the University of Idaho. Topics include the law of radioactivity and the general geochronometry equation, the use common radioactive decay equations such as K-Ar, Ar-Ar, Rb-Sr, and U-Th-Pb, the use of isochrones, concordia diagrams and discordia, the concept of "blocking temperature," the use of ...
