Modeling the interior of the Earth using Seismic Waves part of Quantitative Skills:Activity Collection
Students use a variety of tools to explore the interior of the Earth in this inquiry activity.

Reading Topographic Maps and Calculating Map Scale part of Quantitative Skills:Activity Collection
Use a topographic map to deliniate a watershed, draw a map bar scale, and calculate a map ratio scale.

Density of rocks - How large is a ton of rock? part of Quantitative Skills:Activity Collection
This module addresses the problem of how to determine the size of a ton of rocks of a given composition and invites the student to figure out how to solve the problem.

My Special Place part of Quantitative Skills:Activity Collection
Students pick a place of significance to them (their Special Place) for analysis in this semester-long project. (A model is provided by the instructor using a place the students are not likely to have visited.)

Calculation of the Magnitude of Lunar and Solar Tidal Forces on the Earth part of Quantitative Skills:Activity Collection
Project in which students calculate the magnitude of lunar and solar tidal forces on the earth. They calculate the solar tidal effect relative to the lunar tidal effect and the relative solar tidal effect for spring-tide conditions.

Gulf Anoxia Course Project part of Quantitative Skills:Activity Collection
In this activity students work in groups to investigate the problem of Gulf of Mexico hypoxia before developing mitigation strategies based on local contriubtions to the problem. The students present their ideas in a public meeting debate format from which a solution must be selected by the entire class.

Here we see it, but what's beneath? Effective geologic cross-section problem solving part of Quantitative Skills:Activity Collection
Students will use suface observations from a map to locate subsurface features using geologic cross-sections using topographic profiles, surface data, assessment of variables and data quality. Students will produce a standard scientific report describing the nature and conclusions of the project.
