After having learned about earthquakes in class, through readings and earlier lab assignments, students (in groups of two) are asked to design and construct (using balsa wood, string, paper and glue) a three-story building designed to minimize the effects of shear-wave vibrations that occur during an earthquake. The students are required to research the design concepts on their own and most of the construction work occurs outside of the regular laboratory period. The structures are tested for strength a week before the earthquake occurs - can they support the required load for each floor? On earthquake day, the buildings a tested for a "design earthquake" and then each group is given the opportunity to see how "large" and earthquake their structure can withstand - both in terms of frequency and amplitude variations. In addition to building the structure, each team has to submit a paper reflecting on why they designed and built the structure the way they did.

For this exercise we meet in a computer lab and students access the IRIS Earthquake Browser to download geospatial information of earthquakes. Students use the GEON Integrated Data Viewer (IDV) to explore the location of earthquake zones and their 3-dimensional characteristics. Students compare the earthquake characteristics of subduction zones, mid-oceanic ridges, and transform faults. This leads into a discussion of plate tectonics.

This activity will help students to identify and analyze factors contributing to Earth's climate systems.

The Earth's Interior worksheet involves the layers of the Earth and is meant to help students: 1) Draw the layers of the Earth true-to-scale (on an image with a scale bar), and 2) Grasp the size of the Earth by starting at a somewhat familiar scale (the upper 40km of the crust) and progressively adding layers and increasing the scale to the radius of the Earth (~6,400km). Moving from the familiar to the unfamiliar has been shown to be an effective strategy to understand large magnitudes (Resnick, Shipley, Newcombe, Massey, & Wills, 2012).

Starting at the surface, the student adds layers of the earth as the scale increases (40km, 400km, 700km, 3,000km, and 6,400km). The layers include the base of continental crust, upper mantle, transition zone, lower mantle, and the outer core, as well as drawing the height of a building at the surface to help gain perspective as the scale changes. Students also complete 3 multiple choice questions at the end of the worksheet to solidify and focus on goals and important concepts.

This worksheet uses the sketch-understanding program with built-in tutor: CogSketch. Therefore, students, instructors, and/or institution computer labs need to download the program from the CogSketch website: http://www.qrg.northwestern.edu/software/cogsketch/. At any point during the worksheet, students can click the FEEDBACK button and their sketch is compared to the solution sketch. The built-in tutor identifies any discrepancies and reports pre-written feedback to help the student correct their sketch until they are done with the activity. Once worksheets are emailed to the instructor, worksheets can be batch graded and easily evaluated. This program allows instructors to assign sketching activities that require very little time commitment. Instead, the built-in tutor provides feedback whenever the student requests, without the presence of the instructor. More information on using the program and the activity is in the Instructor's Notes.

We have developed approximately two dozen introductory geoscience worksheets using this program. Each worksheet has a background image and instructions for a sketching task. You can find additional worksheets by searching for "CogSketch" using the search box at the top of this page. We expect to have uploaded all of them by the end of the summer of 2016.

This worksheet helps students visualize Earth's magnetic field, shows how magnetic inclination changes with latitude, and shows how rocks can be tied to specific latitudes of origin based on magnetic inclination recorded in the rock. In this worksheet, students are given a diagram of the Earth with its magnetic field and 8 packages of "rock" with magnetic inclination arrows. Students grab, move, and rotate each rock to determine its latitude of origin by matching the arrows in the "rock" with the magnetic field lines on the diagram of the Earth. By allowing a direct, physical comparison of the magnetic field to magnetic inclinations recorded in rocks, this worksheet reduces the cognitive load of visualizing those spatial relationships. The worksheet includes a problem that walks students through the process of determining movement of a plate that has two bodies of rock with different magnetic minerals.

Spreadsheets Across the Curriculum module. Students build spreadsheets to forward calculate the Earth's aggregate density from combinations of densities and thicknesses of the Earth's four shells.

In this activity students explore the Earth's radiation budget using Earth radiation Budget Experiment (ERBE) data archived at the IRI/LDEO Climate Data Library (more info) .

Students work in pairs on this worksheet and strengthen their background knowledge by identifying different features in photographs of Earth's surface. Then to build on this base, the students need to determine the key processes that form each of the features. To address a common misconception, students read a debate between two hypothetical students and need to determine which student is stating the scientifically correct idea. The project is summarized by a question posed about the features on a hypothetical planet.

This Lecture Tutorial worksheet is designed for students to work on in groups after the students
have learned about basic surface features and how they relate to planets in general. The tutorial
is designed to help students look at these simple features and realize that they are not
independent features, but instead are related to the planet as a whole.

Ebay is a parody of I Want it That Way by the Backstreet Boys a #1 hit from 1999. This song contains animated lyrics and an economic explanation that are synchronized to the music. The song explores a wide range of economic issues including: markets, supply and demand, and gains from trade.

Students in this course explore designs of a future Carleton College student house. This is a multi-year project where students from the social sciences, humanities / arts, and natural sciences explore parts of the design of an actual house.

The ecological autobiography is a multi-stage reflective and written exercise that draws on students' personal history and experiences as they consider the ecological context of some period of their lives. The goal is to individually and collectively explore how the landscapes and ecological communities we have inhabited influence us as individuals, set the context of our lives, and influence our expectations of landscape.

This short lesson was designed in collaboration with a 7th grade Life Science teacher (Paul Jeffery). The idea behind the lesson is to help students better understand ecological and geographical classifications by teaching them at the same time in their Life Science class and their Geography class. Teaching the two classifications together will help reinforce the idea of classification. While this lesson would best be taught outdoors it can also be adapted to the indoors.

This site contains 21 modular, easy to use economic models, that are appropriate for class assignments or in-class demonstrations. Students can simulate all the standard models taught in most economics courses. EconModel uses the Windows OS. The simulations were developed by William R. Parke of the University of North Carolina at Chapel Hill.
