Introduction to Stoichiometry
Our on-line Chemistry course covers stoichiometry and demonstrates our scenario based approach to teaching chemistry. Traditional courses tend to follow a bottom-up approach to learning chemistry. This traditional approach teaches abstract concepts and tools before discussing their practical application, which results in students learning bits of unconnected knowledge that are rarely usable let alone memorable. In our approach, scenarios are used both to motivate the material and provide a frame
Empirical Research Methods
Regression analysis is an enormously popular and powerful tool, used ubiquitously in the social and behavioral sciences. Most courses on the subject immediately dive into the mathematical aspects of the subject and illustrate the technique on problems that are already highly structured. As a result, most students come away with little idea of the wide range of problems to which regression analysis can be applied and how to represent those problems in a way that cleverly utilizes readily availabl
What is a Mammal? Answers from Dr. Ross MacPhee (Beyond Penguins and Polar Bears Podcast Extras)
Through a series of short video segments, we interviewed Ross MacPhee, curator in the Department of Mammalogy of the American Museum of Natural History (AMNH) to give us a basic understanding about polar mammals. A paleomammalogist, he travels around the world studying mammals of the ancient past as well as those of today. In particular, MacPhee studies woolly mammoths, the not-so-distant relatives of our present-day elephants.
In Search of Cosmic Rays
These interactive lessons teach about Cosmic Rays by emphasizing the mystery that Cosmic Rays presented to early scientists. The scientific inquiries and investigations that Cosmic Rays prompted are interesting and important to understanding the way science works. Cosmic Rays are now being studied at research sites around the world. Much has been learned from early experiments and even more is being discovered with modern experiments, but many questions have yet to be answered.
Mathematics for Computer Science
A basic introduction to Calculus and Linear Algebra. The goal is to make students mathematically literate in preparation for studying a scientific/engineering discipline. The first week covers differential calculus: graphing functions, limits, derivatives, and applying differentiation to real-world problems, such as maximization and rates of change. The second week covers integral calculus: sums, integration, areas under curves and computing volumes. This is not meant to be a comprehensive calcu
Radio Fights Jim Crow
During the World War Two years, a series of groundbreaking radio programs tried to mend the deep racial and ethnic divisions that threatened America. At a time when blacks were usually shown on the radio as lazy buffoons, the federal government and civil rights activists used radio for a counter attack. Did radio unify America in the face of war? This is "Radio Fights Jim Crow".
Webquest: The Split Brain
The brain is made up of two halves, the hemispheres. These hemispheres are united to one another through a system consisting of millions of nerve fibers. Therefore, each hemisphere is continually informed about what is happening in the other. What happens if the connection is broken?
Weather is a constantly changing set of phenomena and easily observable. That's why weather also provides an excellent topic for scientific study. Even though meteorology includes some complex science, it is a wonderful example of how scientists make predictions based on measurements and observations. Each of the investigations in this section on Weather are led by an investigative question. It is important that students come to realize that scientists try to find out about the world by asking q
Knowing what ideas children already have about a science topic is critical to providing appropriate learning situations. Time spent revealing the ideas they have is a good investment. Quite apart from alerting you, the teacher, to their current understanding of soil, it also gets them going--focusing them on what they will be doing. It gives students a stake in the learning enterprise; "This is the bit I have to offer." Finally, it fixes a benchmark for each student against which he or she can m
Picking up, examining and collecting rocks can be the first steps in moving children toward an appreciation of geology and the “bones” of the Earth. Children can find a wide variety of rocks in many places, from the school yard to parks and driveways at home. Even very young children enjoy picking up rocks, lining them up, choosing “favorite” ones, pouring water over them to make them shiny and even painting them as gifts for adults. By letting children handle and observe rocks you give

The Metaconstitutional Manifesto: A Bourgeois Vision of the Classless Society
This book describes my concept of the ideal society, one in which bourgeois values of individual liberty, limited government, and market economics, pushed to their logical conclusions, produce a classless society. In this, the one hundred fiftieth anniversary of The Communist Manifesto, I am therefore publishing The Metaconstitutional Manifesto by making it available on the World Wide Web to all people who have access to the Internet.
Thinking About Politics: American Government in Associational Perspective
The goal of this textbook is to provide students with a comprehensive survey of the American political system and with a framework for analyzing its processes and functions. It will appeal to instructors of introductory American government courses who wish to take students beyond a traditional institutional orientation. Throughout the text, the various dimensions of American politics are integrated into an analytical framework designed to stimulate thoughtful understanding of the political world
Wrong Turn: A Sympathetic Critique of the Civil Rights Movement
This book argues that the antidiscrimination laws should be repudiated and repealed, without allowing the reintroduction of Jim Crow rules, rules mandating segregation (de jure) and discrimination. It will turn out that the same principles which forbid Jim Crow law prohibit antidiscrimination law. Towards the end of our analysis, this book examines an overlooked arena which offers considerable promise in combating racism: etiquette. We badly need to develop rules of etiquette appropriate for th
Medical Response to Weapons of Mass Destruction: Nerve Agents

A Handbook for Collecting Releve Data in Minnesota
The exercise describes releve field methods and discusses the multivariate analysis of releve data. The application of releve data to problems of habitat evaluation, forest inventory, and research projects in Minnesota was presented by experts from the Minnesota Natural Heritage Program, the Minnesota County Biological Survey, and the Univ. of Minnesota. All participants received a releve handbook that covered the history of the method, field instructions, data-entry forms, and an overview of a
A Field Study of the Ant Trail Phenomenon
In this exercise, students place food at various distances from an ant hill or nest. Ants are then observes as they find the bait and lead other ants to it. At the completion of the exercise, students construct a graph which shows the establishment of trails, recruitment of workers, and depletion of the bait.
The effect of hunger on children and graphing
Following are a series of activities in which students apply various math skills to better understand the problems of world hunger and what steps are being taken to reduce the number of people without enough to eat. This activity examines the effect of hunger on children and the connection with child mortality, which is another MDG Hunger Target: Halve, between 1990 and 2015, the proportion of people who suffer from hunger. Child Mortality Target: Reduce by two-thirds, between 1990 and 2015, the
