Half Life Model part of Examples
While working in groups to facilitate peer tutoring, students manipulate a hands-on, physical model to better comprehend the nature of half life. Students use the model to simulate the decay of radionuclides. The ...
Weathering Experiment part of Introductory Courses:Activities
This project has students dirty several dishes equally and design experiments to determine which analogs of geologic processes are most efficient for removing the baked-on food. Students calculate rates of ...
Whose Fault Is It Anyway? part of Pedagogy in Action:Library:Games:Examples
This game has students simulate the propagation of P and S waves after an earthquake and to use the lag between these to determine where in the simulation the earthquake occurred.
Fracture Fundamentals: A Cheesy Analog part of Examples
This activity has students make small cuts in processed cheese food and then apply shear stress perpendicular or parallel to the cuts to see what sort of fracturing will occur.
In-classroom Pumping Test part of Hydrogeology:Activities
Students conduct a pumping test in a sand-filled basin or tank in the classroom with either a siphon drain or small fountain pump. Drawdown is measured in small piezometers and students analyze the data to ...
Thermohaline Circulation Demonstration part of Oceanography:Activities
This activity helps the students to visualize the effects of temperature and salinity on water density, and the resulting thermohaline circulation. Important processes visualized in this demonstration are ...
Sonar Demonstration -- Human Sound Wave part of Oceanography:Activities
Sonar technology allowed scientists to produce high-resolution maps of the sea floor for the first time. This sonar demonstration uses a Human Sound Wave to image the "sea floor" in a lecture hall. In ...
Using Lab Measurements to Determine the Feasibility of a Photovoltaic Panel part of Integrate:Workshops and Webinars:Systems, Society, Sustainability and the Geosciences:Activities
Using Lab Measurements to determine the power output of a solar module and the economic feasibility of photovoltaic panels
Magma Viscosity Demos part of Pedagogy in Action:Library:Interactive Lectures:Examples
This is an interactive lecture where students answer questions about demonstrations shown in several movie files. They learn to connect what they have learned about molecules, phases of matter, silicate crystal structures, and igneous rock classification with magma viscosity, and to connect magma viscosity with volcano explosiveness and morphology.
