Using Lab Measurements to Determine the Feasibility of a Photovoltaic Panel part of Integrate:Workshops: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

Subject: Environmental Science:Energy:Energy Principles , Engineering, Environmental Science:Energy:Renewable & Alternative Energy, Environmental Science:Sustainability

Igneous Rocks Model part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
While working in groups to facilitate peer tutoring, students use samples of four igneous rocks (gabbro, basalt, granite, and rhyolite) to observe differences in texture, color and grain size and make inferences ...

Subject: Geoscience:Geology:Igneous and Metamorphic Petrology:Igneous Rocks

Subduction Zone Earthquakes part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
While working in groups to facilitate peer tutoring, students manipulate a hands-on, physical model to better comprehend several characteristics of subduction zone earthquakes.

Subject: Environmental Science:Natural Hazards:Earthquakes, Geoscience:Geology:Tectonics, Geophysics:Seismology

Earthquake Demonstration part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
This demonstration uses an "earthquake machine" constructed from bricks, sand paper, and a winch, to simulate the buildup of elastic strain energy prior to a seismic event and the release of that energy during an earthquake.

Subject: Environmental Science:Natural Hazards:Earthquakes, Geoscience:Geology:Structural Geology:Microstructures, Deformation Mechanisms, Fabrics

Crystallization from Melt Demonstration part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
This demonstration uses melted phenyl salicylate to show how crystals nucleate and grow as the temperature of the liquid melt decreases.

Subject: Geoscience:Geology:Mineralogy:Crystal Chemistry, Geoscience:Geology:Igneous and Metamorphic Petrology:Igneous Processes

Copper Extraction Demonstration Tutorial part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
Summary This demonstration uses sulfuric acid and crushed copper ore (malachite) to produce a solution of copper sulfate and carbonic acid in a beaker. When a freshly sanded nail is dropped into the copper sulfate ...

Fog Chamber part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
Show how clouds and fog are created with a very simple physical model. Materials needed are: A large 1 gallon jar, latex glove, a little water, and matches.

Subject: Geoscience:Atmospheric Science:Meteorology:Clouds and precipitation

Phases of the Moon part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
This exercise has students use a simple physical model of the Earth, sun, and moon to understand why the moon changes phases from the perspective of Earthly observers.

Subject: Geoscience:Lunar and Planetary Science

Slinky and Waves part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
Use a Slinky to show:P and S waves, Wave reflection, and Standing waves in interactive lecture demonstration.

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.
