How Large is a Ton of Rock? -- Thinking about Rock Density part of Spreadsheets Across the Curriculum:General Collection:Examples
Len Vacher, University of South Florida
Spreadsheets Across the Curriculum module. Students build spreadsheets to calculate the edge length of cubes and diameter of spheres of various rocks starting with their mineralogic composition.

Measuring specific gravity to answer questions about subduction. part of Quantitative Skills:Activity Collection
Leslie Kanat, Johnson State College
Use a quadruple beam balance to measure the specific gravity of the minerals and rocks that are common in oceanic and continental lithosphere. The results of the calculations are tied to numerous concepts described in previous lectures.

Density of rocks - How large is a ton of rock? part of Quantitative Skills:Activity Collection
Len Vacher, University of South Florida
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.

GEOLogic: Lagerstatten and Unique Fossils part of Quantitative Skills:Activity Collection
Laura Guertin, Penn State Brandywine
Students are asked to match up several unique fossils with the site and location where it was found and it's geologic age.

Calculation of the Magnitude of Lunar and Solar Tidal Forces on the Earth part of Quantitative Skills:Activity Collection
Randal Mandock, Clark Atlanta University; Randal Mandock, Clark Atlanta University
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.

Quantitative Classroom Exercises part of Quantitative Skills:Activity Collection
Steven Schafersman, The University of Texas of the Permian Basin
The four exercises give students an opportunity to use their knowledge of graphs, algebra, and maps to solve simple geological problems.

GEOLogic: Terrestrial and Jovian Planets part of Quantitative Skills:Activity Collection
Laura Guertin, Penn State Brandywine
In this two-part example, students are given clues about properties about the terrestrial and Jovian planets respectively and asked to match up the planet with the correct equatorial radius, mean orbital velocity, and period of rotation.

GEOLogic: Volcanologists part of Quantitative Skills:Activity Collection
Laura Guertin, Penn State Brandywine
students are asked to resolve how many days each of 5 volcanologists spent at a volcano and what day they started for the volcano. There is also a second part where students are asked to do some additional research about volcanoes on the web.

GEOLogic: The Three Stooges and Their Pet Dinosaurs part of Quantitative Skills:Activity Collection
Laura Guertin, Penn State Brandywine
Students are asked to match up each of the Stooges with their favorite group and species of dinosaur based on clues given from different perspectives.

GEO-Logic: Continental Drift and Plate Tectonics part of Quantitative Skills:Activity Collection
Laura Guertin, Penn State Brandywine
Students are asked to match up lecturers with what day and time they teach, and how many students they have based on clues given from several different perspectives. In the second part of the activity, students are asked to learn more about the historic figures mentioned in the activity by doing reading and web research.
