This website is for teachers of chemistry in schools and colleges.
It is a collection of experiments that demonstrate a wide range of chemical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Chemistry Freeware. On this page I post reviews and links to freeware chemistry programs available for download at other sites around the internet.
All of the programs are ones that I have used, or currently use. None-the-less, I take no responsiblity for any problems you might experience as a result of installing any of these applications. Unless otherwise noted, the programs are for Windows systems. ACD/ChemSketch 12 Freeware. ACD continues to release updates to the outstanding Chemsketch freeware. MolView.Org is a web-based molecular viewing and modeling tool. Discovery Studio Visualizer 4. ChemAxon produces a wide range of Java-based chemistry tools, and they offer free academic licenses (you must register with them). The Virtual Laboratory from the ChemCollective is a personal favorite. KnowItAll Academic Edition - In a continued commitment to academia, Bio-Rad is offering this completely FREE and fully functional software package to promote learning and research in the academic community.
2002 Personal Account: Chemistry Lesson. (2002, England) I am a high school science teacher in Birmingham.
I usually teach physics, but due to teacher shortages, I ended up teaching chemistry a few years ago. As you all know, chemistry can be fun, especially when you get onto the subject of reactive metals. I decided to liven up a particular chemistry lesson by demonstrating the awesome energy released when silver nitrate, magnesium, and a drop of water are mixed. This particular reaction is very violent, exploding in a brilliant white flash when the water is added. It usually ends up shattering the crucible. I carefully mixed the powders in the bone-dry mortar, stepped back, and at arms length added a drop of water with a pipette. Interactive Periodic Table. Chemistry Dictionary. Xe Files.

There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations.
If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach. Harrington Periodic Tables So we start this effort tabula rasa (without preconceived ideas). 1) All atoms have a default "common denominator" structure at 270 mass units, irrespective of the element under discussion.

Liquid Crystals. Lists of Nobel Prizes and Laureates Liquid Crystals Play the Crystallite Game Play the Mainstream Game About the game A liquid crystal is a substance that flows like a liquid but maintains some of the ordered structure characteristic of crystals.
Under certain circumstances, phases, liquid crystals have a liquid-like behaviour and during others they have the opposite behaviour. The Nobel Prize The 1991 Nobel Prize in Physics was awarded for showing how simple analogies can be used to understand more complex systems such as liquid crystals and polymers (plastics), which behave like solids and liquids at the same time.
