RSC.org: Mass Spectrometry
This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of mass spectrometry, using a magnetic sector instrument to demonstrate how specific m/z ratios can be selected. The theory and operation of MS, including the chemistry of ionization and fragmentation is described at an introductory level. There\'s also an excellent example of the use of high resolution MS to differentiate between nominal mass and actual mass. The video does a very good job of explain
Population Genetics and Statistics
This website is part of the President\'s DNA Initiative and is devoted to past and current methods of macromolecules such as DNA. This website introduces the student to the subject of population genetics and stresses factors that can alter allele frequencies in a population and calculations associated with the Hardy-Weinberg principle. The student will learn to use acceptable statistical approaches to evaluating DNA data and how DNA databases are constructed and applied. This site is designed as
HPLC Tutorial 2,0 Video
This high quality video resource focuses on partition chromatography. The video presents an overview of basic separation theory and discusses instrumentation and data analysis. The size of the video (62.6 MB) almost requires a high speed internet connection. The resource can be downloaded to the user\'s computer, which is recommended for those with slower connections.
This website provides resources that can aid in the interpretation of NMR proton shifts, identification of IR features and mass loss identification in mass spectrometry. The original site is in German, but most (but not all) the content is translated on the English version of the site. From the left hand menu under Spektroskopei-Tools choose Wizards. From here you can enter a chemical shift in ppm and the NMR tool will identify likely protons and environments that could cause the shift. Enter a
Physical Chemistry Online
Physical Chemistry Online (PCOL) Is a collection of physical chemistry modules that address specific concepts in an open-ended, collaborative fashion. The PCOL collection contains fifteen guided inquiry modules covering five broad topics: thermodynamics, kinetics, polymers, computational chemistry, and spectroscopy. Many modules provide the students with an industrial context auch as the evaluation of raw materials or the development of new products. Students that participate in these modules ar
This site provides an introduction to the use of multiple regression, beginning with a glossary of important terms before taking the reader through a review of bivariate regression and the implementation and interpretation of multiple regression. One limitation to the site is its reliance on Minitab for calculations. Users, however, can reproduce the calculations using other software packages, such as SPSS or Excel. Prior knowledge of the basics of bivariate regression is assumed; thus, the site

Assignment Discovery: Fibonacci Sequence
Leonardo Da Vinci explored the idea of the golden mean which is also found in one of the most famous number sequences known as the Fibonacci Sequence. Learn more about this sequence on Discovery Channel's "Assignment Discovery."
Everything You Ever Wanted to Know about Nanoindentation
The Nanoindentation Website, Hosted By Baker's Group At Cornell, provides an introduction with illustrations to nanoindentation, the underlying mechanism, and applications. The Website is well laid out and easy to navigate. A novel feature of this website is an electronic forum that allows registered users of the site to ask questions about the technique. The site is likely to be useful to students studying materials science, nanotechnology, and surface science.
Organic Chemistry On Line
This site covers introductory material related to the analysis of small organic molecules by mass spectrometry, UV-visible, IR, and NMR spectroscopy. A concise explanation of each approach is presented with illustrations. This would be useful for those teaching organic chemistry and for others who need a review of the topic. The section on Spectroscopy Resources at the end of the site contains a list of links to additional information plus a several links to compilations of problems (and their s
Animations in an Instrumental Methods Chemistry Class?
This website provides an introduction to animations as a tool for teaching instrumental techniques in the instrumental analysis course - why one might wish to use animations, some information on how to go about developing them, and it provides a number of examples of animations for analytical instrumentation. One problem with the site is that some of the animations emphasize instrumentation that is not frequently used today. For example, the section on ICP shows an instrument with the classical
Lead in DC Water
This site is a PowerPoint presentation describing the problem with lead in Washington, DC, drinking water. The presentation is interesting and well illustrated. It contains a discussion of the basic chemistry involved with this problem. It is potentially useful for a broad range of interests from high school through university level courses in environmental chemistry. It does not contain any significant amount of material on chemical analysis (lead determinations in water are well covered i

The Kissing Hand by Audrey Penn Read A Loud
In this video read a loud students will meet Chester raccoon who is nervous about starting school. He talks to his mother about his fears. She comes up with a wonderful solution to help her little raccoon remember that she loves him. Each page of the book is shown as the narrator reads it aloud. This is a great teaching resource to read on the first day of school for younger elementary students. (4:46)

The Little Mouse, The Red-Ripe Strawberry and the Big Hungry Bear by Don and Audrey Wood Read A Loud
First published in 1984, a picture book in which the Little Mouse will do all he can to save his strawberry from the Big, Hungry Bear, even if it means sharing it with the reader. Each page of the book is shown as narrator reads it aloud. This is a good companion teaching resource to help bring literary characters to life.

"Little Gidding" by TS Eliot (poetry reading)
This is the latter half of this poem. "All shall be well, and all shall be well, and all manner of things shall be well." is a quotation from Dame Julian of Norwich. http://revpatrickcomerford.blogspot.com/2008/09/all-shall-be-well-and-all-manner-of.html http://en.wikipedia.org/wiki/Julian_of_Norwich This is the same tenet of religious faith is sometimes expressed as "It's all good" - that whatever happens is all part of God's masterplan - and ultimately for the best. A similar idea was expr
