Unit 3: What's in YOUR watershed? part of Eyes on the Hydrosphere: Tracking Water Resources
In this unit, students investigate water resources of their own area or another area of personal interest, which typically gets them very excited. They apply their knowledge from Units 1 and 2 to identify the water ...

Unit 2: Monitoring surface and groundwater supply in central and western US part of Eyes on the Hydrosphere: Tracking Water Resources
In Unit 2, students learn how the techniques for water budgeting (covered in Unit 1) can be used to monitor both groundwater (High Plains Aquifer) and surface water (western mountain watershed) systems. Students ...

Unit 2: Geophysical Properties of the Subsurface part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
Archie (1950) defined the term petrophysics to describe the study of the physics of rocks, particularly with respect to the fluids they contain. Although originally focused on geophysical exploration, petrophysics ...

Unit 4: Groundwater, GPS, and Water Resources part of Measuring the Earth with GPS
GPS data can measure ground elevation change in response to the changing amount of groundwater in valleys and snow cover in mountains. In this module, students will learn how to read GPS data to interpret how the ...

Unit 3: Field Geophysical Measurements part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
Near-surface geophysical measurements are performed by moving sensors across the earth's surface. Active geophysical sensors transmit a signal into the earth and record a returned signal that contains ...

Unit 4: Comparing risks at different volcanoes part of Monitoring Volcanoes and Communicating Risks
Students assess the risks from three different volcanoes based on the Risk Equation, Risk = Hazard x Value x Vulnerability. The three volcanoes--Fuego Guatemala, Rinjani Indonesia, and Moana Loa Hawaii--have ...

Unit 1: Collecting GPS Data part of Measuring the Earth with GPS
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 1: Monitoring Volcanic Activity at Mount St. Helens part of Monitoring Volcanoes and Communicating Risks
How can data from an impending volcanic dome-building event be used to forecast the hazard to a surrounding community? In this activity, students will examine geodetic data (GPS and lidar) and seismic data in a ...

Unit 5: Integrated Geophysical Interpretation and Comparison with Ground Truthing part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
In this unit, students explore spatial associations between the three-dimensional electromagnetic (EM) conductivity inversions and the visible patterns of Salicornia (pickleweed) introduced in Unit 1, Exploring ...

Unit 2: Kilauea Hawai'i - Monday Morning Meeting at the USGS Hawai'i Volcano Observatory part of Monitoring Volcanoes and Communicating Risks
How do volcanologists at the Hawaiian Volcano Observatory monitor volcanoes? In a jigsaw format, students first work in teams to learn one of the four volcano monitoring data sets (GPS, Tilt, Seismic and InSAR) and ...
