This board game is used to introduce the concepts of energy use in our lives and the very real impact that personal choices can have on our energy consumption, energy bills and fuel supply. The game begins as each student selects cards that define their mode of transportation and home design. The players roll dice and move around the board, landing on "choice" or "situation" blocks and selecting cards that describe consumer choices and real life events that impact their energy consumption and annual energy bills. As the players pass gasoline stations or energy bill gates, they must pay annual expenses as defined by their original cards, with amounts altered by the choices they've made along the way. Gasoline cards are collected to represent their total consumption. Too many gas guzzling vehicles can result in total depletion of their gasoline supply -- at which point everyone must walk or ride the bus. At the end of the game, the players count their remaining dollars to determine the winner. Discussion questions probe the students to interpret what choices they made and situations they encounter have the most impact on their energy consumption and energy bills. All game board, card and money files are available on-line free of charge.

We all know that it takes energy to provide us with the basics of shelter: heating, cooling, lighting, electricity, sanitation and cooking. To create energy-efficient housing that is practical for people to use every day requires combining many smaller systems that each perform a function well, and making smart decisions about the sources of power we use. Through four lessons on the topics of heat transfer, circuits, daylighting and electricity from renewable energy sources, students learn about the science, math and engineering that go into designing energy-efficient components of smart housing that is environmentally friendly. Through numerous design/build/analyze activities, students create a solar water heater, swamp cooler, thermostat, model house, model greenhouse, and wind and water turbine prototypes. Students should concurrently be taking Algebra 1 in order to complete the worksheet calculations.

The Energy Systems and Solutions Unit brings students through the exploration of science and engineering concepts as they relate to energy issues in everyday life. Issues surrounding energy production and energy consumption provide a relevant theme for learning basic science, math and engineering concepts, and also provide a convenient platform for introducing current scientific and technological developments into the curriculum. Energy-related issues touch on the lives of each and every student. This project-based curriculum follows an engineering problem solving approach; students simultaneously learn and use scientific and mathematical content and processes as they solve an energy-related problem that is meaningful to them. By challenging them with a problem to solve, students are engaged in scientific and engineering processes, thereby reinforcing subject matter retention and targeting a wide range of learning styles in the classroom. The Energy Systems and Solutions Unit can be broken into three main sections. The first section includes various activities designed to help students understand the problem at hand -- namely, the issues surrounding our energy situation - so that they can realize the importance of what they will be studying and the significance of their proposed solutions. An understanding of the problem will form the basis for the student learning that takes place in the second section, which includes basic energy concepts (forms, states, conversions, efficiency, etc.), content that is required by state and federal science educational standards, but they will learn these concepts by participating in a variety of engaging activities that intend to show the relevance of the science material to the real world as well as to the solution of their assigned problem. Finally, in the last section of the unit students apply the concepts they have learned as they complete a culminating project that requires students to consider what action they can take to reduce our dependence of fossil fuels or otherwise provide a positive solution for our current energy crisis.

This module introduces estimation theory and its terminology, including bias, consistency, and efficiency. In searching for methods of extracting information from noisy observations, this chapter describes estimation theory, which has the goal of extracting from noise-corrupted observations the values of disturbance parameters (noise variance, for example), signal parameters (amplitude or propagation direction), or signal waveforms. Estimation theory assumes that the observations contain an information-bearing quantity, thereby tacitly assuming that detection-based preprocessing has been performed (in other words, do I have something in the observations worth estimating?). Conversely, detection theory often requires estimation of unknown parameters: Signal presence is assumed, parameter estimates are incorporated into the detection statistic, and consistency of observations and assumptions tested. Consequently, detection and estimation theory form a symbiotic relationship, each requiring the other to yield high-quality signal processing algorithms.

My goal is to provide an accessible book that reflects this theme of choice and conveys a sense of the breadth and power of basic economic analysis. It assumes no prior knowledge of economics and can be read and appreciated by anyone. While some parts of the book cover conventional material, others do not. I've ignored many traditional topics and substituted ones that apply economics in unusual and often provocative ways. The chapters are not meant to be definitive, they are meant to raise questions. If they do not make you think or ruffle an occasional feather, I have failed. Most chapters use a story-telling approach that has served me well in the classroom. I am accustomed to a tough audience. Every semester I stare into the fresh faces of college students who would rather be at the beach, students who challenge me to make them care. I use stories to grab their attention, to show how economics affects their everyday life, and to give them a new and deeper appreciation of what drives their behavior.
