Modeling Rare Plant Distributions Using ArcGIS
Elizabeth Crook, University of California-Irvine
In this activity, students work with rare plant occurrence data from the Nature Reserve of Orange County, California to create species distribution maps in ArcGIS. Students are given shapefiles of species ...

Measuring Ground Motion with GPS: How GPS Works
Shelley E Olds, EarthScope Consortium
With printouts of typical GPS velocity vectors found near different tectonic boundaries and models of a GPS station, demonstrate how GPS work to measure ground motion.GPS velocity vectors point in the direction that a GPS station moves as the ground it is anchored to moves. The length of a velocity vector corresponds to the rate of motion. GPS velocity vectors thus provide useful information for how Earth's crust deforms in different tectonic settings.

Converging Tectonic Plates Demonstration
Shelley E Olds, EarthScope Consortium
During this demo, participants use springs and a map of the Pacific Northwest with GPS vectors to investigate the stresses and surface expression of subduction zones, specifically the Juan de Fuca plate diving beneath the North American plate.

Pinpointing Location with GPS Demonstration: How GPS Works (Part 2)
Shelley E Olds, EarthScope Consortium
Using string, bubble gum, and a model of a GPS station, demonstrate how GPS work to pinpoint a location on Earth.Precisely knowing a location on Earth is useful because our Earth's surface is constantly changing from earthquakes, volcanic eruptions, tectonic plate motion, landslides, and more. Thus, scientists can use positions determined with GPS to study all these Earth processes.

Unit 2: Modeling Population
Kirsten Menking, Vassar College; David Bice, Pennsylvania State University-Main Campus
In this unit, students create three different STELLA models to explore a variety of concepts related to population growth and resource use. The first model simulates the classic lynx-snowshoe hare predator-prey ...

Indiana River Meanders Mapping Exercise
Emily Zawacki, Arizona State University at the Tempe Campus
In Indiana, major rivers and their tributaries cross much of the state. These rivers can produce significant hazards related to flooding and erosion, which threaten nearby residents and infrastructure. Rivers are ...

Measure surface reflectance and albedo with smartphone apps
Jessie Turner, Old Dominion University
Using smartphones, students can measure the reflectance and albedo of water and other earth surfaces in the field. This is a great activity to reinforce the central concepts used in remote sensing. The smartphone ...

Unit 1: Collecting GPS Data
Karen M. Kortz (Community College of Rhode Island) Jessica J. Smay (San Jose City College)
GPS data can measure vertical and horizontal bedrock motion caused by a variety of geologic processes, such as plate movement and the changing amount of water and ice on Earth's surface. In this unit, students ...

Unit 4. Urban Landscapes and Water Use
Gigi Richard, Fort Lewis College
Students are introduced to evapotranspiration (ET) and how ET varies with meteorological factors and plant factors. A pre-class video and worksheet introduce students to estimating landscape water needs from ET and ...

Unit 2.1: Hydrologic Impact of Land-Use Change
John Ritter, Wittenberg University; Meghann Jarchow, University of South Dakota; Ed Barbanell, University of Utah
In this activity, students model the impact of land-cover changes on stormwater runoff using the EPA's National Stormwater Calculator (Calculator). The students are introduced to the Calculator through a ...
