In this audio slideshow, an ecologist from the University of Florida describes the radiocarbon dating technique that scientists use to determine the amount of carbon within the permafrost of the Arctic tundra. Understanding the rate of carbon released as permafrost thaws is necessary to understand how this positive feedback mechanism is contributing to climate change that may further increase global surface temperatures.

In this activity, students explore the web-based U.S. Forest Service Climate Change Atlas to learn about projected climate changes in their state and how suitable habitat for tree and bird species is projected to change by 2100.

SSAC Physical Volcanology module. Students build a spreadsheet and apply the ideal gas law to model the velocity of a bubble rising in a viscous magma.

In this activity, students learn about the scientific evidence supporting climate change, use this information to evaluate and improve conclusions some people might draw about climate change, and participate in a role-play to negotiate solutions to climate change.

Spreadsheets Across the Curriculum module/Geology of National Parks course. Students study how discharge per unit area varies with elevation in the high country of Glacier National Park from USGS hydrograph data from Swiftcurrent Creek and its tributary Grinnell Creek..

As the core activity of petrology portion of a mineralogy/petrology course, students cooperatively conduct petrographic and electron microprobe analytical studies on suites of Central Blue Ridge metamorphic rocks collected during class field activities. We make use of a remotely operable electron microprobe instrument at the Florida Center for Analytical Electron Microscopy (FCAEM) to conduct all analyses in class.

SSAC Geology of National Parks module/Geology of National Parks course. Students calculate probabilities using USGS hydrograph data, a spreadsheet of daily stage heights, and the COUNTIF function.

In this activity, students will use oxygen isotope values of two species of modern coral to reconstruct ambient water temperature over a four-year period. They use Microsoft Excel, or similar application, to create a spreadsheet of temperature values calculated from the isotope values of the corals by means of an algebraic equation. Students then use correlation and regression techniques to determine whether isotope records can be considered to be good proxies for records of past temperatures.

This activity engages learners in examining data pertaining to the disappearing glaciers in Glacier National Park. After calculating percentage change of the number of glaciers from 1850 (150) to 1968 (50) and 2009 (26), students move on to the main glacier-monitoring content of the module--area vs. time data for the Grinnell Glacier, one of 26 glaciers that remain in the park. Using a second-order polynomial (quadratic function) fitted to the data, they extrapolate to estimate when there will be no Grinnell Glacier remaining (illustrating the relevance of the question mark in the title of the module).

Spreadsheets Across the Curriculum module/Geology of National Parks course. Students use a topographic map and spreadsheet to find how many Big Macs they burned off on a five-mile hike at Catoctin Mountain Park.

In this short activity, students create a timeline of climate science over the past 200 years and gather information from a U.S. Forest Service video about mitigation and adaptation strategies undertaken by the Service to address climate change in national forests.

The University of Florida Book of Insect Records (UFBIR) names insect champions and documents their achievements. Each chapter deals with a different category of record.

Spreadsheets Across the Curriculum module/Geology of National Parks course. Students estimate travel times and costs of a driving/camping trip to visit national parks in the Colorado Plateau.

Spreadsheets Across the Curriculum module/Geology of National Parks course. Students use foundational math to study the velocity of the North American Plate over the hot spot, the volume of eruptive materials from it, and the recurrence interval of the cataclysmic eruptions.
