Analytical Electrochemistry: Potentiometry
This courseware module is structured for either a lecture presentation or self-study tutorial on analytical potentiometry. The level of presentation spans upper high school to college students. Topics include historical background, theory/principles, instrumentation, pH electrodes, experimental examples, and troubleshooting tips.
Animation of Single Head Check Valve HPLC Pump
This animation site is specifically about reciprocating pumps for liquid chromatography. 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) are also listed on ASDL.
Animation of diode array detection in HPLC
This animation site deals specifically with diode array detection for liquid chromatography. 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) are also listed on ASDL. This site requires FLASH version 7 or
Electronics - Tutorial
An encyclopedic collection of descriptions of electronics circuitry and principles to introduce or reacquaint readers with a wide variety of concepts. The site is very well organized to access the information needed. In addition to passive and active components, electricity and magnetism are also described.
RSC.org: UV/Vis Spectroscopy
This video distributed on YouTube is on the basic principles of UV/Vis. Provides a good primer (~5 min), and the top-off look of the instrument is useful in explaining components. A double beam instrument is described.
Veeco's Nanotheater provides over 350 images of surfaces acquired using atomic force microscopy and scanning probe microscopy. Images come from a wide variety of samples, including polymers, biologicals such as bacteria, and inorganic crystals. Many of the images contains brief descriptions of what is being shown, although the information is not particularly in-depth. Additional information on atomic force microscopy and scanning probe microcopy, including useful guides and animations, is availa
Enivronmental Health and Toxicology
This site is packed with information related to the topic of environmental health and toxicology. There is an excellent tutorial section specifically targeted toward aducators and students. The site has a wealth of information about chemicals used in industry and in the average household. This site would be beneficial to students working on environmental problems or trying to understand the chemicals they encounter on a day-to-day basis. The variety of toxicology and environmental health databas
Atomic Structure and the Periodic Chart
Online eText gives a thorough descriptive overview of atomic structure. The site is organized into sections on light particles and waves, the Bohr atom, the quantum atom, atomic electron configuration, and periodic properties. Hyperlinks to interactive demonstrations of physiochemical principals with questions posed are included. At the end of each section, flowcharts, called \"concept maps\" guide the students from basic principles to working concepts.
This activity poses the question: What would happen if a meteor or comet impacted Earth? Students simulate an impact in a container of sand using various-sized rocks, all while measuring, recording and graphing their results and conclusions. Then students brainstorm ways to prevent an object like this from hitting the Earth.
What Is an Electoral College for Presidential Elections?
The electoral college for presidential elections is a body of electors that makes the final decision on who will be elected president based on how the population in the state votes. This two minute video explains how the number of electors for each state is based on the number of congress members for that state. Provides an adequate explanation, but does not explain how the slate of electoral college voters is selected in each state.

Learn about The Geology of the Earth
This 4:42 video provides a quick overview of the geology of the Earth with good graphics. It would be best to include a handout of terms, such as plates, to help the students. Shows how earthquakes occur as well as other events such as volcanic action.
Car Safety Tips in Children
This three minute video shows the importance of using baby seats in cars. It does not tell you how to identify a good one and is weak on showing how they should be belted at different ages. At best, this is a warning video for parents.
