Stream Characteristics Lab part of Quantitative Skills:Activity Collection
Wendy Van Norden, harvard-westlake school
Students determine the relationship between the sinuosity of a river and its gradient by calculating gradients and sinuosity, and generating a graph on Excel. They then test the relationship by making measurements on a picture generated on Google Earth.

Flood Frequency and Risk Assessment part of Quantitative Skills:Activity Collection
Carol Ormand, Carleton College
Students calculate recurrence intervals for various degrees of flooding based on historical data. Students then do a risk assessment for the surrounding community.

Stokes' Law Exercise for "Rocks and Minerals" part of Quantitative Skills:Activity Collection
Karen Bartels - Northeastern Illinois University - Chicago, IL
Students in a lab qualitatively "derive" Stokes' Law by timing the settling of various objects through given fluids.

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

Density of Rocks - Some Applications part of Quantitative Skills:Activity Collection
Len Vacher, Dept of Geology, University of South Florida
This module studies some applications of being able to determine the density of rocks.

The Earth's Shells - Thicknesses and Densities part of Quantitative Skills:Activity Collection
Len Vacher, Dept of Geology, University of South Florida
This module explores the combination of densities and shell thicknesses that produce an aggregate density of the Earth of 5.5 g/cm3.

Question of the Day: Ocean Waves #2 part of Starting Point-Teaching Entry Level Geoscience:Interactive Lectures:Question of the Day
Surfers know that the best waves from distant storms have periods of about 14 seconds. The object of this activity is to compute how long it takes the 14 second period waves to travel 6,000 km across the pacific. ...

Using functions in an introductory geoscience course part of Quantitative Skills:Activity Collection
Jennifer Wenner, University of Wisconsin-Oshkosh
A template and two exercises (CO2 and population growth) designed to increase the graphical literacy of students in introductory geoscience and mathematics courses.

Prework for Rivers and Streams Lab (Intro Geology) part of Quantitative Skills:Activity Collection
Rachel Teasdale, California State University-Chico
In order to give Introductory Geology (Physical Geology) undergraduate non-majors students experience and confidence in using basic algebra to calculate very simple stream flow properties, we use a prework assignment prior to the Rivers and Streams Lab. Prework is a worksheet assigned 2 weeks in advance, which asks students to calculate velocity and discharge as well as unit conversions and calculations of stream load. The questions are put into the context of activities they completed earlier in the semester during visits to the stream (on campus) so questions are relevant to their previous experiences. The prework timeframe gives students the opportunity to seek extra help from their instructor prior to the lab period in which they will make additional measurements, similar calcualations and interpretations of their data.

Westward Ho! How Far is Yonder Mountain part of Quantitative Skills:Activity Collection
Len Vacher, Dept of Geology, University of South Florida
PowerPoint module leading students through development of a spreadsheet to calculate the distance of a mountain peak from coplanar vertical angles shot from two points a known distance apart.
