Density of Earth - Using Some Field Data 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 density of the earth and has students do some field experiments to get the data they need to answer the problem.

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.

Population Growth, Ecological Footprints, and Overshoot part of SISL:2012 Sustainability in Math Workshop:Activities

Rikki Wagstrom

In this activity, students develop and apply linear, exponential, and rational functions to explore past and projected U.S. population growth, carbon footprint trend, ecological overshoot, and effectiveness of hypothetical carbon dioxide reduction initiatives.

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.

How much energy do you save by doubling insulation? part of SISL:2012 Sustainability in Math Workshop:Activities

Joseph Skufca

Students will be provided the governing equation for steady state heat transfer across a surface. They will use that equation to explore the effect of changing the insulation value on the amount of energy used.

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.

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.

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.
