# Green Math, Engineering & Technology

## An Introduction to the High School Green Math Curriculum Unit

The *Green Math Curriculum Project* was initiated to spread the themes of sustainability throughout the High School curriculum. Starting with the math curriculum we hope to connect math concepts to technologies and considerations surrounding the new green economy and to engage students in real-world examples of the use of their math skills.

The materials were originally developed to meet the needs of teachers in pre-algebra, Algebra I and II. As you will see there are a few higher level lesson plans as well as a strong link to statistics. The lessons in this document have been arranged into green topic specific units although there are many worksheets and resources in each one that could easily be rearranged into stand alone pieces or units that are more math content specific.

In addition to the more traditional lessons there is an engineering project which is a multiple-day unit which challenges students to consider green engineering in the building of a temporary shelter to be used in a disaster situation. This project truly encompasses idea of the sweet spot in sustainability between environment, economics and social equity.

**Green Math & Engineering Lessons Index of Mathematical Concepts**: This document details the major mathematical concepts and which lesson units grouped by green topic include which Mathematical concepts. Use this document to plan your mathematical concepts instruction schedules.*Download:*[doc]**Buyer Beware**: Students will use stem and leaf plots, histograms, circle graphs and other methods of data display as well as explore simple probability while learning about ingredients in everyday cosmetics.*Download:*[doc]**Cell Phone Series**: Students access and review statistical concepts and graphical representations to investigate the issues of sustainability surrounding a personal electronics item that they use every day. Students estimate and rewrite large numbers, calculate the mean of a given data set, calculate the median, upper and lower quartiles of a data set using algebraic and graphical methods, construct a box-and-whisker plot for a given data set.*Download:*[Intro ppt] [doc]**Lifecycle and Sustainability**: Students understand how to evaluate a product or process for “Green”. Students will be introduced to the sustainability triangle, be introduced to the lifecycle diagram, use these tools to evaluate a product.*Download:*[doc]**Ecological Footprint**: To use a personal ecological calculator to look at the impact that each human has on the environment. Objectives: Students will use an online tool to calculate their own ecological footprint.*Download:*[doc]

**Got Gas**: Students use information about gasoline to assess or review students’ ability to solve word problems involving basic arithmetic operations, and to analyze and interpret their results. Students will understand the concept of miles per dollar solve word problems using basic arithmetic operations analyze and interpret results.*Download:*[doc]**The Big Melt**: Students will use research on ice cap melting to formulate an exponential decay equation. Students will compute the decline of the summer Arctic ice pack formulate an equation that incorporates the variable as the exponent (exponential).*Download:*[doc] [ppt]

**No Dung**: Students use information on factory farming to assess or review problem solving skills involving basic arithmetic operations, unit conversions, as well as, area and volume calculations. Students will solve word problems using basic arithmetic operations, solve word problems that require unit conversions, solve word problems involving area and volume.*Download:*[doc]**Plastic Bags**: Students compute ratios with large numbers and study the effects of plastic bag consumption in countries across the world. Students will analyze data given on plastic bag consumption around the world break the consumption down to per person/year/week/month use this information to draw conclusions about their own consumption and ways to reduce plastic bag usage.*Download:*[doc]**Population**: Students apply statistical modeling tools to world population data. The models that students develop will then be used to predict the population of the world in 2050. Students will calculate ratios and percentages. Represent data via circle graphs. Use exponential equations to make calculations. Model data using trend lines and the regression capabilities of the graphing calculator.*Download:*[doc] [ppt]

**Truckin’ to your Table**: Students investigate food sources using statistics and percentage applications and consider the carbon footprint of the food we consume.*Download:*[doc]**Waste Generation**: A multiple lesson unit where students explore municipal waste and its impacts upon communities. Students will read and interpret various graphs, use estimation, use percentages and fractions, correlation coefficients and use function notation.*Download:*[doc] [ppt]

**Water Bottle Unit**: This unit gives students an understanding of the waste generated through consuming bottled water. To use Statistics, Linear Algebra, Functions and Regression Models to analyze data in order to make an environmental decision.*Download:*[doc] [ppt]

**What are You wearing?**: This lesson uses information to graph linear inequalities about the comparisons between the growing of hemp and cotton.*Download:*[doc]
