Discovering the Principles of Relative Age Determination – a Think-Pair-Share In-Class Activity
James Ebert, SUNY College at Oneonta
In this in-class activity, students are challenged to identify rock units and geologic features and determine the relative ages of these features without prior instruction in the classical methods of relative age determination.
Learning how to constuct a graph of a decaying isotope and using it in radiometric dating
Ntungwa Maasha, College of Coastal Georgia
Students learn how to construct and use the natural decay curve for use it in a laboratory exercise on the use of radioactivity in absolute dating.
Accuracy, Precision, and Topographic Data
Scott Linneman, Western Washington University
This jigsaw style exercise challenges new geomorphology students to collect topographic data and analyze its accuracy and precision.
Reasons for the Seasons
Jeff Thomas, Central Connecticut State University
The inquiry method and meteorological and astronomical online data can be used to elicit the inconsistencies of students' naïve ideas about the "real" reasons for the seasons. The first phase of this two-part investigation uses online meteorological data to identify factors that might explain differences of seasonal temperatures among cities These factors are used to hypothesize why differences of seasonal temperatures occur among cities. During the second phase, the variables and hypotheses that were previously identified in part one are used to design and conduct an inquiry-oriented investigation. Astronomical data is used as part of the investigation to "test" students' hypotheses— conclusions are drawn then communicated.
Calculating the radius of the Earth
Basil Tikoff, UW Madison
Science students often have difficulty thinking about large spatial scales. The purpose of the exercise is to redo Eratosthenes' calculation of the radius of the Earth using data from to sites in ancient Egypt. The excercise teaches about the methodology of science - how Eratothenes figured it out - rather than worried about what the "right" answer is. It can also be used to discuss the role of models in geological thinking.
Evaluating the lines of evidence for plate tectonics
Becca Walker, Mt. San Antonio College
In this in-class exercise, students compare several lines of evidence that support the ideas of continental drift and plate tectonics. Before the class meeting, each student is given a preparation assignment in which he/she studies one "continental drift" and one "ocean floor data" map. In class, students divide into teams of 3, with each team member having prepared different specialties. They discuss their respective maps and look for spatial patterns among the data.
Energy Balance Game
Bob Mackay, Clark College
This online game activity introduces students to Earth's radiative energy balance. It also explores the use of a simple climate model in the attribution of climate change.
Investigating Stream Energy and Gradient Using Small Stream Tables
Beth Dushman, Del Mar College
In this Physical Geology lab activity, students investigate the relationship between stream energy and gradient by changing the gradient of a small stream table and observing changes in stream erosion.
Exploring the nature of geoscience using cartoon cards
Anne Egger, Central Washington University
In this activity, students work in groups to put a set of cartoon cards in order, much in the way that we might assemble a geologic history. The primary goal of the activity is to explore the nature of science in general and the nature of geoscience or historical science specifically, without requiring any content knowledge.
Riparian Plant Lab
Julie Stoughton, University of Nevada-Reno
In this field exercise for an introductory environmental science course, students investigate plant cover and type in a riparian area using transects. The final assignment is a lab report that includes a summary data table, a graph of cover types along their transect and an analysis of riparian health.
