Geologic Puzzles: Morrison Formation part of Examples
Images of faulted strata, tilted turbidites, and beach rocks bring the field into the classroom, giving students practice in doing what geoscientists do. These images are examples of geologic puzzles.
Hotspot Lesson: Mantle Plumes part of ERESE:ERESE Activities
This lesson introduces the theory of mantle plumes and possible ways of finding evidence to support the theory.
How Fast Do Materials Weather? part of Examples
A think-pair-share activity in which students calculate weathering rates from tombstone weathering data.
Carbon Dioxide Exercise part of Examples
Students work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years.
Hotspot Lesson: Hotspot Theory and Plate Velocities part of ERESE:ERESE Activities
This activity provides the students with a data set of ages of some of the Hawaiian Volcanoes and seamounts and how far they are from the active volcanism (considered to be the location of the hotspot). By plotting the data on a graph and fitting the data with a line of best fit, the plate velocity can be estimated by taking the slope of the line.
Hotspot Lesson: Samoan Hotspot part of ERESE:ERESE Activities
This lesson discusses the similarities and difference between Samoa and Hawaii. Both Samoa and Hawaii are island chains in the Pacific and thought to be the result of hotspots.
Magma Viscosity Demos part of 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.
Describe and Interpret Images: Folded Strata part of Examples
In class, have students make a simple sketch of an outcrop shown in a slide (or computer projection) then discuss possible interpretations.
Rivers: Short In-class Activity part of Examples
Images of the James River in Virginia, including one at flood stage, and of potholes, all of which can be used to have the students make observations, estimates, and interpretations.
Hotspot Lesson: Relative Dating part of ERESE:ERESE Activities
This lesson explains the application of relative dating for volcanic features in the ocean.
