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 ...
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 ...
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.
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.
Demonstration of radioactive decay using pennies part of Quantitative Skills:Activity Collection
A demonstration (with full class participation) to illustrate radioactive decay by flipping coins. Shows students visually the concepts of exponential decay, half-life and randomness. Works best in large classes – the more people, the better.
Subduction Zone Earthquakes part of 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.
Igneous Rocks Model part of 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 ...
Fog Chamber part of 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.
