Examine the graph of two points in the plane. Find the slope of the line that passes through the two points. Drag the points and investigate the changes to the slope and to the coordinates of the points.
The future of energy, environment
The lasting effects of energy consumption on the environment continue to be a problem as the world's population requires more and more energy. This informational piece, part of a series about the future of energy, introduces students to environmental issues related to the use and production of energy. Fossil fuels, nuclear energy, hydropower, and clean air are discussed in the context of environmental quality. Students can read about the development of environmentally friendly vehicles and follo
Science and Technology
The goal of engineering is to solve practical problems through the development or use of technologies. Technology/engineering works in conjunction with science to expand our capacity to understand the world.
Powering the U.S.
This lesson provides students with an overview of the electric power industry in the United States. Students also become familiar with the environmental impacts associated with a variety of energy sources.
Discovering Properties of Matter
What is matter? How do we define it? What are some of its properties that we can measure? Come learn all about this fundamental piece of science in this Wowie clip from the Children's Museum of Houston. Cynthia briefly discusses the following properties of matter: shape, texture, magnetism, fluorescence, and mass. (0:59)
How Lead Batteries are Made
Batteries are great examples of chemical potential energy, energy that is stored up. Find out how lead batteries are made and what causes the chemical reaction as we take a trip to the Superior Battery Manufacturing Company on Discovery Channel's "HowStuffWorks" show. (02:49)
Lecture 5a: Functional Analysis - Nowhere dense sets
The fifth class in Dr Joel Feinstein's Functional Analysis module covers proofs that countably infinite complete metric spaces must have isolated points. Nowhere dense sets and nowhere dense closed sets. Further module materials are available for download from The University of Nottingham open courseware site: http://unow.nottingham.ac.uk/resources/resource.aspx?hid=bd32d53b-3c12-ac19-176b-d9e112731951 and on iTunes U: http://itunesu.nottingham.ac.uk/albums/64.rss Dr Feinstein's blog may be vie
Passover Matzo (3:15)
In this video watchers learn why the matzo is traditionally eaten during Passover. This explains how it is made.
Analytical Electrochemistry: A Laboratory Manual
This labware module contains directions for seven experiments in analytical electrochemistry. The experiments are designed to illustrate fundamentals of electrode reactions as applied to readily accessible redox reactants. They provide insight to dynamic electrochemistry for scientists at all levels of training. Activation procedures to prepare glassy carbon electrodes are provided in a TechNote.
Active Learning in Advanced Analytical Chemistry, a course for first year graduate students
The introductory lecture course for graduate-level analytical chemistry is commonly understood to require students to be broadly aware of analytical tools, current problems, and methods for linking problems and measurements. This article describes an active learning approach to this course, using review articles to focus discussion and reveal gaps in student knowledge. Students give most of the course\'s lectures, with grades based on lectures, exams, and a term paper.
GC Splitless Injection Animation
This site is one in a series of sites with very good animations related to separations. This animation deals specifically with splitless injection in GC. The animations are short (one to two minutes) and can easily be shown in class as part of a lecture. They are extremely helpful in illustrating key components and concepts of chromatographic systems. Users are encouraged to explore the site and the other brief animations as well. Separate links to other simulations by the same company (TRSL) ar
RSC.org: IR Spectroscopy
This video on YouTube covers the basic principles of infrared spectroscopy. Very useful for a newcomer to IR. This video of 6.5 minute would be useful in a classroom setting or students interested in the technique.
RSC.org: Proton NMR
This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of NMR. This video is a good primer and would be very useful to supplement introductory lectures on NMR. The video covers the basic theory behind a 1H spectrum and goes through actually acquiring a spectrum. The top-off look of the instrument is useful and how the superconducting magnet is mounted. Good for a basic introduction.
This pair of pH calculation programs serves as an excellent tool for anyone wishing to calculate the pH of a solution containing multiple acids and bases. These programs allow practitioners to predict the pH of simple and complex acid/base solutions and buffers. Users are encouraged to carefully read the guides provided by the author.
The Strongest Pump of All
In this lesson the students will learn how the heart functions. Students will be introduced to the concept of action potential generation. The lesson will explain how action potential generation causes the electrical current that causes muscle contraction in the heart. Students will be introduced to the basic electrical signal generated by the heart; P, QRS, and T waves. The lesson will approach the heart from an engineering standpoint and encourage students to design ways to improve heart funct
DRC Plenary: Joan Snyder, 2010-11 Estelle Lebowitz Visiting Artist-in-Residence
Wednesday, February 28, 2011 Joan Snyder received the MacArthur Fellowship Award (popularly known as the "Genius Award") in 2007, and her paintings have been exhibited widely throughout the United States. She founded the Women Artist Series at Douglass College in 1971 (which has since then been renamed the Mary H. Dana Women Artist Series). A concurrent survey exhibition of her small paintings from 1965-2010, Joan Snyder/Intimate Works, is on view at the Mabel Smith Douglass Library Galleries t
Quantitative Skills Assessment of Geoscience Courses
The importance of quantitative skills in earth science education is the primary subject addressed by this website. This website is not a quantitative course, however this document does provide numerous useful techniques that can be employed in a variety of other coursework to advance the quantitative skills of the student. The first section of this website presents a checklist that can be used to develop exercises which will focus on specific quantitative applications and evaluations. Skills add
Gerry Wright on the Michael G Degroote Institute for Infectious Disease Research
Gerry Wright, director of the Michael G Degroote Institute for Infectious Disease Research at McMaster University, talks about the work performed in his lab and by his colleagues.
