Unit 5: Agriculture and Freshwater Pollution part of Water, Agriculture, Sustainability
Units 3 and 4 of this module explored how water resources are used for agriculture in the United States and how this can vary depending on location. In Unit 5, students explore how agricultural practices can affect ...

Unit 3: Crops and Irrigation Patterns in the United States part of Water, Agriculture, Sustainability
This unit is designed to allow students to quantitatively assess how much water is used for irrigating crops and how this varies across the United States. This unit also has students link water use to the economic ...

Unit 4: GPS and infinitesimal strain analysis part of GPS, Strain, and Earthquakes
Students work with GPS velocity data from three stations in the same region that form an acute triangle. By investigating how the ellipse inscribed within this triangle deforms, students learn about strain, strain ...

Unit 1: Earthquake! part of GPS, Strain, and Earthquakes
In this opening unit, students develop the societal context for understanding earthquake hazards using as a case study the 2011 Tohoku, Japan, earthquake. It starts with a short homework "scavenger hunt" ...

Unit 6: Applying GPS strain and earthquake hazard analyses to different regions part of GPS, Strain, and Earthquakes
Students select their own set of three stations in an area of interest to them, conduct a strain analysis of the area between the stations, and tie the findings to regional tectonics and societal impacts in a 5–7 ...

Unit 5: 2014 South Napa Earthquake and GPS strain part of GPS, Strain, and Earthquakes
The 2014 South Napa earthquake was the first large earthquake (Mag 6) to occur within the Plate Boundary Observatory GPS network (now Network of the Americas- NOTA) since installation. It provides an excellent ...

Unit 3: Getting started with GPS data part of GPS, Strain, and Earthquakes
This unit provides essential background information on GPS (global positioning system) and reference frames. Students learn how to access GPS location and velocity data from the Network of the Americas (NOTA). They ...

Unit 2.1: Hydrologic Impact of Land-Use Change part of An Ecosystem Services Approach to Water Resources
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 ...

Unit 5: Oceans in Protection: Marine Protected Areas part of Ocean Sustainability
Students will review current ocean pressures related to overfishing and human impacts on ocean ecosystems. By examining data collected in relation to the presence of marine reserves, students will explore long-term ...

Unit 3: Oceans As Habitat: Sustaining Life in the Ocean part of Ocean Sustainability
Students will be able to identify the functional roles that organisms play in ocean ecosystems. How do human-induced changes in ocean conditions affect biodiversity, and thereby the health and resilience of a coral ...
