Erosion in a River
Nicole LaDue, Northern Illinois University
× Formative assessment questions using a classroom response system ("clickers") can be used to reveal students' spatial understanding. Students are shown these diagrams and instructed to ...

Grand Canyon Cross Section Lab
Doug Lombardi, University of Maryland-College Park
× Students examine a geologic map of the Grand Canyon and two imaginary vertical cores through canyon stratigraphy. They use these data to construct a cross-section across the canyon and to answer questions ...

Modeling Folds: Block Diagrams and Structure Contours
Basil Tikoff, University of Wisconsin-Madison Naomi Barshi, University of Wisconsin-Madison Carol Ormand, SERC, Carleton College
Working in small groups, students build Play-Doh models of 3 folds (one upright, one vertical, one plunging). They slice each of their models to create 3D block models, sketch block diagrams of each fold, and ...

Feedback Loops
Alexandra Davatzes, Temple University
This assignment requires students to use analogical reasoning to identify the key attributes, the causal structure, that make a feedback loop positive (by amplifying/accelerating the effect) or negative (by ...

Resistance to Weathering
Nicole LaDue, Northern Illinois University
Formative assessment questions using a classroom response system ("clickers") can be used to reveal students' spatial understanding. Students are shown this diagram and instructed to "Click on ...

Introduction to Structure Contours
Basil Tikoff, University of Wisconsin-Madison
Students construct structure contour lines for a "dipping bed" in our classroom and on a geologic map. In my class, this is a multi-day activity. In part 1 of this exercise, students use "topographic ...

Introduction to Modeling Folds
Basil Tikoff, University of Wisconsin-Madison
Students make Play-Doh models of synclines and anticlines, including one of a plunging fold. They use these models to answer questions about what these structures look like in map view and cross-sectional view.

Wakemup Pluton
Basil Tikoff, University of Wisconsin-Madison
Students work through a set of questions about a geologic map of an igneous intrusion and surrounding rock units. These questions focus students' attention on the topography, geomorphology, lithology, and ...

Modeling Unconformities
Basil Tikoff, University of Wisconsin-Madison
Students make models of various kinds of unconformity: disconformity, angular unconformity, and buttress unconformity. They examine those models from a variety of perspectives and consider how each one appears in ...

Introduction to Modeling Faults
Basil Tikoff, University of Wisconsin-Madison Naomi Barshi, University of Wisconsin-Madison Carol Ormand, SERC, Carleton College
Students use Play-Doh to explore the map patterns created by faulting + erosion. We begin with simple scenarios and progress to more complex possibilities.
