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 ...
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. -
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 ...
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. -
Sonar Demonstration -- Human Sound Wave part of Cutting Edge:Courses: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 Melting Ice to Teach Radiometric Dating part of Quantitative Skills:Activity Collection
Students are challenged to a Sherlock Holmes-style mystery in which they construct their own decay curves of melting ice to determine time-zero.
Exploring Radiometric Dating with Dice part of Quantitative Skills:Activity Collection
An activity in which students use dice to explore radioactive decay and dating and make simple calculations.
