| Data | The
Constants and Equations Pages. When a book of data can't be found try here. If you are seriously interested in science or mathematics you may need this site. With over 200 scientific constants and more than 300 equations you're likely to find that elusive formula. There is also planetary information and a large mathematical reference section for algebra, trigonometry, integration, differentiation and more. http://tcaep.co.uk/index.htm |
| Molecular Structure | Molecule of the Month.
. This is a great site for those fascinated by chemistry. View the featured molecule from any angle you choose, provided you've got the right plug-in. The molecular images are available in a variety of formats: HTML, Chime, VRML or Java. Software and helper file links are available so that you can manipulate, rotate, fly around and through the structures. Each page also contains extensive background information on the compounds. http://www.bristol.ac.uk/Depts/Chemistry/MOTM/motm.htm |
| Molecular Structure |
Indiana University Molecular
Structure Centre. Do not be put off by the opening page. This is an easy to use, enjoyable molecular graphics site. X-ray crystallography has provided much of the information for the structures. Start with the new IUMSC look or common molecule links. Manipulate organic and inorganic compounds, amino acids, macromolecules and more. A'level chemists will have fun with the Java based buckyballs and crystal structures. http://www.iumsc.indiana.edu/ |
| Bonding |
NCSA ChemViz. The offer to Waltz and then to DISCO may sound tempting but this is an ambitious, complex chemical visualisation site. To use the interface you need an easy to obtain user name and password. Next, interact with chosen atoms and molecules. The aim is to promote a deeper understand of electron orbitals and molecular bonding theory by experimentation with animations and interactive calculations. Chime and RasMol plug-ins are useful, as is a detailed knowledge of Chemistry. http://chemviz.ncsa.uiuc.edu/ |
| Data | Environment Writer.
Degree level chemists could spend hours browsing this US National Safety Council site. The Chemical Backgrounder Index consists of 100+ elements and compounds. It contains concise information about their uses, physical and chemical properties. Details of possible health effects could help students with any experimental risk assessments. Regulations as to uses, manufacture and environmental emissions relate to the USA. http://www.nsc.org/EHC/ew/chemical.htm |
| Molecular Structure |
The Library of 3D Molecular
Structure. A site for A'level chemistry or biology students who enjoy interactive molecular graphics. An excellent, easy to use accompaniment to your studies. The states of water and allotropes of carbon will link with and take you beyond GCSE, reinforcing work on structural shapes. Hydrocarbons, amino acids, lipids, carbohydrates and the building block of nucleic acids can be explored as your chemical and biochemical knowledge develops. VRML or Chime plug-ins required. http://www.nyu.edu/pages/mathmol/library/ |
| Periodic Table and Chemical Calculations | Chemistry Functions Advanced level Chemistry students will enjoy using this Java based chemical converter. An interactive periodic table can quickly and easily produce relative atomic and compound masses. You can balance those annoying chemical equations, convert masses to moles and visa versa as well as calculate molarity. Of course using a calculator and a book of data may be quicker but not as much fun. http://www.stanford.edu/~glassman/chem/index.htm#pt |
| Acid/Base Theory |
Acid and Base pH Tutorial.
A set of self directed exercises aimed at undergraduate students but equally suitable to A'level chemists. Clear instructions and learning goals make this site a very good revision aid. The Arrehnius Theory and Brønsted-Lowry concept of acid/base behaviour are introduced and along with the more comprehensive Lewis theory form the basis of the work. Self-assessment questions test understanding after each section. http://www.science.ubc.ca/~chem/tutorials/pH/launch.html |
| Biochemistry | Molecular Models for
Biochemistry. An imaginative series of tutorials and quizzes that use chime and rasmol biochemical molecular images to good effect. Intended to complement graduate level texts, the interactive nature of the site provides far more feedback than any traditional information source. Amino acid and peptide structures, protein architecture, nucleic acids (DNA and RNA) and the molecules of metabolic pathways can be rotated viewed as ball and stick, space filled images and more. http://www.bio.cmu.edu/Courses/BiochemMols/BCMolecules.html |
