Geologic Time Calculations part of Quantitative Skills:Activity Collection
Francisco San Juan, Elizabeth City State University
Radiometric age determination using parent/daughter composition and a radiometric decay curve.

Reading Topographic Maps and Calculating Map Scale part of Quantitative Skills:Activity Collection
Leslie Kanat, Johnson State College
Use a topographic map to deliniate a watershed, draw a map bar scale, and calculate a map ratio scale.

Environmental Footprint part of Quantitative Skills:Activity Collection
Christina Gallup, University of Minnesota-Duluth
This activity has students do a web-based environmental footprint quiz and integrate their results into a class mean. The students compare their results by creating a bar graph and do some simple calculations to see how much of the Earth just the population of the US requires.

Understanding Radioactivity in Geology: The Basics of Decay part of Quantitative Skills:Activity Collection
Christina StringerUniversity of South Florida, Tampa FL 33620 This activity was developed for Spreadsheets Across the Curriculum . National Science Foundation, DUE 0442629.
PowerPoint module leading students through creation and manipulation of spreadsheet to forward model an example of exponential decaythe number of remaining unpopped kernels of popcorn in a bag of popping popcorn.

Stream Characteristics Lab part of Quantitative Skills:Activity Collection
Wendy Van Norden, harvard-westlake school
Students determine the relationship between the sinuosity of a river and its gradient by calculating gradients and sinuosity, and generating a graph on Excel. They then test the relationship by making measurements on a picture generated on Google Earth.

Investigating dimensions of the solar system part of Quantitative Skills:Activity Collection
Francisco San Juan, Elizabeth City State University; Steven Schafersman, University of Texas of the Permian Basin, The; Michael Stewart, University of Illinois at Urbana-Champaign
Planetary data are used to investigate and evaluate the Nebular Hypothesis.

Kohler Curves part of Quantitative Skills:Activity Collection
Swarndeep Gill, California University of Pennsylvania
An assignment teaching students about Kohler curves that enhances their quantitative skills.

Discharge and Sediment Transport in the Field part of Quantitative Skills:Activity Collection
Jeff Clark, Lawrence University
In this quantitative field activity, students collect field data on channel geometry, flow velocity, and bed materials. Using these data, they apply flow resistance equations and sediment transport relations to estimate the bankfull discharge and to determine if the flow is sufficient to mobilize the bed.

The Changing Geographic Distribution of Malaria with Global Climate Warming part of Quantitative Skills:Activity Collection
Mary Savina, Carleton College; Kendra Murray
In this exercise, students analyze climate data to find areas in the southern United States that are now close to having conditions in which the malaria parasite and its mosquito hosts thrive and then attempt to forecast when areas might become climatically suitable.

Time Series Analysis of Lehigh Valley Instrumental Climate Records part of Quantitative Skills:Activity Collection
Zicheng Yu, Lehigh University
In this lab activity the students will learn basic statistical and graph skills by analyzing real world climate data sets.
