Half Life Model part of Starting Point-Teaching Entry Level Geoscience:Interactive Lecture Demonstrations: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 ...

How Many Is A Million? part of Cutting Edge:Topics:Rates and Time:Visualizations with Teaching Notes
Roger Steinberg, Department of Natural Sciences, Del Mar College Description To help students visualize the immensity of geologic time, or even the immensity of just one million years, I have created a very large ...

Subject: Geoscience: Geoscience:Geology:Historical Geology

Weathering Experiment part of Cutting Edge:Courses: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 Starting Point-Teaching Entry Level Geoscience: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. -

Subject: Geoscience: Geoscience:Geology, Environmental Science:Natural Hazards:Earthquakes

Igneous Rocks Model part of Starting Point-Teaching Entry Level Geoscience: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: Geoscience:Geology:Igneous and Metamorphic Petrology:Igneous Rocks

Earthquake Demonstration part of Starting Point-Teaching Entry Level Geoscience: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 ...

Fog Chamber part of Starting Point-Teaching Entry Level Geoscience: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: Geoscience:Atmospheric Science:Meteorology:Clouds and precipitation

Copper Extraction Demonstration Tutorial part of Starting Point-Teaching Entry Level Geoscience: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 ...
