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.

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.

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.

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.

Choosing Between Home Appliances: Benefits to the Planet and Your Wallet part of SISL:2012 Sustainability in Math Workshop:Activities

Corri Taylor, Wellesley College

Students research various options for new appliances and make purchasing decisions based not merely on purchase price, but also on energy efficiency, which has implications for the planet AND for longer-term personal finances. Students calculate the "payback period" for the more energy efficient appliance and calculate long-term savings.

A Monarchy Deposed: The Demise of the Monarch Butterfly part of SISL:2012 Sustainability in Math Workshop:Activities

Daniel Abel

Monarch butterflies (scientific name: Danaus plexippus) migrate annually to forests in central Mexico from Canada and California. Those surviving the 1200 - 2800 mile migration overwinter in Mexico. In this activity, students will learn about the conservation biology of monarch butterflies, threats to their survival, the implications of their potential extinction, and ways to protect the species.

One day it is too hot and other days it is too cold. Do we need to replace the HVAC system? part of SISL:2012 Sustainability in Math Workshop:Activities

Monika Kiss

This project will allow students to create a mathematical model to help in making decision about replacing HVAC units on a large scale.

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.
