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.

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.

Reading Topographic Maps and Calculating Map Scale part of Quantitative Skills:Activity Collection

Leslie Kanat, Johnson State College

Use a topographic map to deliniate a watershed, draw a map bar scale, and calculate a map ratio scale.

Weathering of Minerals part of Quantitative Skills:Activity Collection

Wendy Van Norden, harvard-westlake school

Students determine the % change in mass of mineral samples that have been placed in a rock tumbler. They graph the relationship between the hardness of the mineral and the % change in mass. They then consider why some of the mineral samples do not conform the the relationship they graphed. They investigate the physical properties of the outliers and consider how the physical properties contributed to the rate of weathering, and what kind of weathering occured in the rock tumbler.

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.

Who Goes There? Estimating Ocean Populations in Chincoteague Bay part of SISL:2012 Sustainability in Math Workshop:Activities

Maria Hernandez; Itnuit Janovitz-Freireich

In this activity students use data to: rank species on the food chain, compute energy flow ratios and estimate fish populations in the Chincoteague Bay. Students also discuss the impact of the ecosystem and humans on this population, with an extension activity calculating the biodiversity of the system.

How Biodiverse is Lake Superior? An exercise in proportions. part of SISL:2012 Sustainability in Math Workshop:Activities

Stephanie Kajpust

Students use critical thinking and algebra to measure and evaluate the biodiversity in Lake Superior.

Salt Marshes: estimation techniques using basic algebra and geometry part of SISL:2012 Sustainability in Math Workshop:Activities

Yelena Meadows; Sharareh Nikbakht

The activity allows for learning about salt marshes ecosystem and practicing of basic math in estimations.
