UMEA University Analytical Chemistry Teaching Resources - This extensive, well organized hotlist of teaching resources should serve as an excellent starting point for chemistry teachers. Be sure to check out Matters of Public Concern for relevant issues and Curiosities Related to Chemistry for some fun enrichment ideas. By Knut Irgum of Umeå University in Sweden.

The smoke and fumes released from burning fossil fuels combine with moisture to produce acid rain. Join schools from around the globe to determine if the pH level of rainwater is affected by proximity to a fossil fueled power plant. This project was designed in conjunction with the Center for Improved Engineering & Science Education at Stevens Institute of Technology in New Jersey. It appears to be an annual project. Check the website for details.

Chemistry can be easy to understand and fun. At this site, learn about elements and how they combine to make compounds. Read great explanations of basic terms along with handy tips and tricks to help you learn concepts like bonding and electron orbitals. Discover how the periodic table got its name and why it is a helpful organization for studying the elements. From Andrew Rader Studios.

This site celebrates all things chemistry, with lesson plans, labs, worksheets, activities, handouts, and tests for teachers, as well as a helpdesk and tutorial links for students; also available in Spanish.

Nigel Saunders, Harrogate Granby High School, North Yorkshire. Requires Java.

The Global Water Sampling Project - In this science project, middle school and high school students gather and share data to compare the water quality of a local river, stream, lake or pond with other fresh water sources around the world. Projects run in Fall and Spring. This project is from the Center for Improved Engineering and Science Education (CIESE) located at Stevens Institute of Technology in Hoboken, New Jersey.

You have to go a lab to have a test run following a trip to the doctor. Why? This site will tell you, in fairly plain language, what tests look for andEhow that test is done. Articles include Inside the Lab and Follow the Sample. Chem and Life Science lab teachers might want to use this site in the classroom to tie in good lab habits and careers.

ChemCom, a chemistry curriculum written for secondary school students by the American Chemical Society, attempts to enhance science literacy by emphasizing chemistry's impact on society. This web site offers information about ChemCom and the ChemCom e-mailing list, links to relevant Web sites, eight real-world, problem-based units, and more. TEMPORARILY UNAVAILABLE.

This water quality testing project encourages inquiry investigations of water quality in North Carolina and Delaware, but teachers outside these states will also find useful links, information, and lesson plans. Developed by Lisa L. Grable and April J. Cleveland for Science Junction.

From the New York University Scientific Visualization Laboratory, MathMol (Mathematics and Molecules) is designed to serve as an introductory starting point for those interested in the field of molecular modeling. Includes Hypermedia Textbooks and K-12 Activities.

Scienceinthebox.com covers a range of interesting and entertaining topics! The site was created to share the science behind Proctor & Gamble's laundry and cleaning products with a focus on addressing sustainable practices and products which embrace social responsibility as well as environmental practices. Product development and other considerations are presented. Users can select topics can be saved into a File Basket, downloaded, and printed. The interactive pages are particularly fun - especially the history of washing - http://www.scienceinthebox.com/en_UK/publications/interactivecontents_en.html. The glossary in the side menu provides definitions for numerous chemicals and terms. Product safety sheets can get pretty technical; so there's something for everyone here on a subject that we might not give much thought.
