This chemistry calculator presents a spreadsheet applet which can be used by students to check solutions to problems, by teachers to devise questions, by lab technicians to prepare solutions. Example applications are supplied. http://chemistrycalculator.com/less.html
See various pictorial versions of the periodic table, together with a wealth of additional Periodic tables by the dozen and all kinds of approaches to the periodic table are linked from this site; if you have the patience to sift through them all, go to http://www.chemistrycoach.com/periodic_tables.htm#Periodic Tables. Otherwise use our selections below
See various pictorial versions of the periodic table, together with a wealth of additional information including links to many other periodic table sites at http://chemlab.pc.maricopa.edu/periodic/periodic.html
For comprehensive information on elements of the periodic table go to http://www.webelements.com/
For another well-presented interactive periodic table which also gives brief properties of families or groups of elements, try this page which began as a student project, http://www.chemicalelements.com/
A table of all the nuclides; lists all isotopes of all elements http://www2.bnl.gov/ton
John Dalton and atomic theory in his own words. This site is also has a long list of other chem-history primary source material. http://webserver.lemoyne.edu/faculty/giunta/dalton.html
John Dalton, a biography written (fictionally) by his brother: http://www.woodrow.org/teachers/ci/1992/Dalton.html
Lots of primary source material can be found at http://dbhs.wvusd.k12.ca.us/Chem-History including Aston (mass spectrometer, in an article referring back to Dalton, Ramsay, Crookes, Rutherford, Soddy, J.J.Thomson), Avogadro, Bohr, Bronsted, Cannizzaro, Meitner, Moseley, Rutherford, Thomson…)
From Lawrence Berkeley National Laboratory, an accessible level explanation of atomic structure and how we know about it: http://particleadventure.org/
Considering formation of elements in the stars, select from huge collections of instructional material at the NASA site, http://spacelink.nasa.gov/Instructional.Materials/Curriculum.Support/Space.Science/Stars.Galaxies.and.Amazing.Phenomena/.index.html
or the Space Telescope Science Institute, http://oposite.stsci.edu/pubinfo/pr/2000/06/pr-photos.html
Services and software for the perfume, flavor, food and beverage industries; good reference for organic chemistry http://www.leffingwell.com/
This site of web links for the secondary chemistry teacher is worth investigating: http://www.thecatalyst.org/m01gener.html
And another site which is simply an index of links, some directed to secondary chemistry; others more general and more advanced. http://www.educationindex.com/chem/
Biographies of more than twenty significant figures (Becquerel, Bohr, Chadwick, Compton, the Curies,... Lise Meitner, ... Rutherford, Seaborg...in the history of radiation are found at http://www.orcbs.msu.edu/radiation/radhistory/radfiguresmain.html
A general chemistry text, "Chemystery". This site won an award in 1997, but it consists of mostly text with unimpressive diagrams. Locally produced print texts are much more impressive and comprehensive, But if you have a student who wants extra references, you might like to try http://library.thinkquest.org/3659/
The American Iron and Steel Institute site has a learning section with articles by different experts covering the steel industry. Lots of text, but diagrams could be clearer. Two animated process diagrams are good. To extend what you would find in your textbook, go to http://www.steel.org/
Surfactants and surface tension - all you could possibly want to know can be found from this virtual library of web links. For chemistry info, go to the applications section of http://www.surfactants.net/
All you could want to know about polymers in context, their uses, their structure,and their chemistry is to be found at the excellent Macrogalleria section of the site produced by the University of Southern Mississippi's School of Polymers and High Performance Materials. Make sure you visit http://www.psrc.usm.edu/
The American Chemical Society site has a page devoted to national historical chemical landmarks program. Included are discovery of acetylene, electrolytic production of bromine, aluminium produced by electrolysis... The site also has an education section, starting at K-8 level. Go to http://www.acs.org/landmarks/
A no-frills tutorial program which students may find useful for independent study, and teachers may find useful for explanations. http://www.chemtutor.com/
All you want to know about acids and bases and pH is in this tutorial from the University of British Columbia. Senior secondary level. http://www.science.ubc.ca/~chem/tutorials/pH/launch.html
Some study resources for secondary school students are found in the ChemTeam site. Interesting historical asides and a section of historical primary sources extend assorted topics beyond the usual textbook level. The ChemTeam site can be accessed from this NZ url: http://learn.lincoln.ac.nz/phsc102/ChemTeamIndex/
Structural formulae for many organic chemicals can be searched at the Sigma site, http://www.sigma-aldrich.com
A chemistry text, laboratory activities and some additional study aids; almost entirely text; some interesting historical and background material; worth a look. http://www.nidlink.com/~jfromm/3rd1000.htm
