GEOLogic: Terrestrial and Jovian Planets part of Quantitative Skills:Activity Collection
Laura Guertin, Penn State Brandywine
In this two-part example, students are given clues about properties about the terrestrial and Jovian planets respectively and asked to match up the planet with the correct equatorial radius, mean orbital velocity, and period of rotation.

GEOLogic: Volcanologists part of Quantitative Skills:Activity Collection
Laura Guertin, Penn State Brandywine
students are asked to resolve how many days each of 5 volcanologists spent at a volcano and what day they started for the volcano. There is also a second part where students are asked to do some additional research about volcanoes on the web.

GEOLogic: The Big Five Mass Extinctions part of Quantitative Skills:Activity Collection
Laura Guertin, Penn State Brandywine
Students are asked to match up the five largest mass extinction events with their relative dates, approximate duration, and severity (percentage of species that became extinct) based on clues given from various perspectives.

Landscape Diffusion Lab part of Quantitative Skills:Activity Collection
Kirsten Menking, Vassar College
Students create a STELLA model of two marine terrace platforms separated in elevation by a cliff, using the hillslope flux equation to simulate the change in the cliff face over time as diffusive processes tear it down.

Temperature Profiles in Permafrost part of Quantitative Skills:Activity Collection
Kirsten Menking, Vassar College
Students use STELLA to create a model of heatflow in permafrost to attempt to replicate the findings of Lachenbruch and Marshall (1986), who used inflections in the geothermal gradient of Alaskan permafrost to search for evidence of climatic change.

Using Popcorn to Simulate Radioactive Decay part of Quantitative Skills:Activity Collection
Jennifer Wenner, University of Wisconsin-Oshkosh
Popping popcorn in your class is an excellent way to illustrate both the spontaneity and irreversible change associated with radioactive decay. It helps students to understand the unpredictability of decay.

M&M Model for Radioactive Decay part of Quantitative Skills:Activity Collection
Jennifer Wenner, University of Wisconsin-Oshkosh
A tasty in-class demonstration of radioactive decay using two colors of M&M's. Illustrates the quantitative concepts of probability and exponential decay. This activity is appropriate for small classes (<40 students).

Introduction to Texas Hurricanes part of Quantitative Skills:Activity Collection
Oney Fitzpatrick, Jim Jordan, and Jim Westgate - Lamar University, Beaumont, TX
Students graph data from 20th century hurricanes that affected the state of Texas. Along the way they answer questions that ask them to interpret what they see represented on the graphs.

Illustrating Hillslope Diffusion with Physical and Numerical Models part of Quantitative Skills:Activity Collection
Gregory Hancock, College of William and Mary
This problem illustrates how numerical theories are developed, how we might test this theory with an analog model, and how numerical models are constructed and the limitations of numerical modeling.

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.
