Modeling the carbon cycle of the anthropocene part of Quantitative Skills:Activity Collection
Heather Stoll, ETH Zurich
Students use an Excel sheet to complete forward and inverse models of changes in carbon distribution between atmosphere, ocean and the biosphere from 1751 to the present and several centuries into the future. The model is given as a mostly complete package, into which students input emissions data in various sensitivity tests.

Investigation: When will there no longer be glaciers in Glacier National Park? part of Quantitative Skills:Activity Collection
An Investigation Question activity developed by Carol Ormand, Wittenberg University.
Students use historical data on the extent of the Grinnell Glacier in Glacier National Park to estimate when the glacier will melt completely.

Air-sea Interactions: Activities in Oceanography part of Quantitative Skills:Activity Collection
Steve LaDochy, California State University-Los Angeles
This online set of activities help students learn properties of ocean waves, wind-wave relationships and properties of tsunamis.

Global Phosphorus Cycle part of Quantitative Skills:Activity Collection
Kirsten Menking, Vassar College
Students create and modify a STELLA model of the global phosphorus cycle to test a number of scenarios.

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.

Back-of-the-Envelope Calculations: The Scale of the Atmosphere part of Quantitative Skills:Activity Collection
Barb Tewksbury, Hamilton College
Question Let's imagine a scale model of the Earth and use a basketball to represent the Earth. Now, let's get ourselves some packages of fruit roll-ups and start covering the basketball with layers of ...

Machines that change climate: Porsche 911 Turbo vs. Toyota Prius part of Quantitative Skills:Activity Collection
Kevin Harrison, McDaniel College
This problem illustrates how consumer decisions can influence carbon dioxide levels in the atmosphere, how to make back-of-the-envelope calculations, and demonstrates the power of exponential growth.

BotEC: The Scale of Earth's Atmosphere part of Quantitative Skills:Activity Collection
Peter Kresan
Question: Air is our most precious resource. Without food, we can live for weeks and without water, we can live for days. But without air to breathe, we survive about 4 minutes! If you visit the top of Mt. Lemmon ...

Genetic and Empirical Approaches to Classifying Climates part of Quantitative Skills:Activity Collection
Charles Dodd, Shoreline Community College
Students (in groups of 3-4) are given a hypothetical planet and create a genetically based climate regionalization. Students then interpret empirical data of various climate phenomena (precipitation, temperature, evapo-transpiration) from different locations on the planet, and apply these to the Koppen system of climate classification.
