This annotated bibliography shares the best "pictures" of chemistry and art from past issues of the Journal of Chemical Education—many thousands of well-crafted words and articles that tie in with National Chemistry Week's 2001 theme, Celebrating Chemistry and Art.

This annotated bibliography collects the best that past issues of JCE have to offer for use with this year's National Chemistry Week periodic table theme. Each resource has been characterized as mainly reflecting one of these categories: activity, calculation, demonstration, experiment, informational, software/video, Web tutorial, or WebWare item; however, several fit more than one classification. The most recent articles are listed first. An indication of the levels the article may serve are included.
Water sources such as lakes, rivers, and ground water supply much of the water for domestic use. Some of the water that reaches our household faucets has also been used for other purposes. Water from these various sources is treated to remove impurities and to make it suitable for human consumption. Several steps can form the treatment process. Large items and particles can be filtered out using screens. Some particles may be allowed to settle out. This can be aided by first adding lime (CaO) to produce a basic solution. Alum (KAl(SO4)2) is then added, which reacts with hydroxide ions (OH– ) to form Al(OH)3, a precipitate which settles out of solution, taking small particles with it. Additional particles can be removed by filtration through sand. Activated charcoal has been treated to increase its porosity and surface area, and is used to adsorb odors and some colored substances. Certain impurities, including carbon-based particles and chlorine, are attracted to the charcoal and remain trapped in the pores. Water is also disinfected using chemical treatments, commonly chlorine. In this Activity, students make a water filtration column using a two-liter plastic bottle that contains layers of gravel, sand, and activated charcoal. They contaminate a sample of water and examine the filtration ability of the column.See related Classroom Activity Connection.
a new pump water rocket. We filled the lime-green plastic rocket to the mark with pool water, snapped it on to the hand-held pump, and underwent a flurry of pumping. Pressed the release, and let it rip. We experimented. How high would it go? What if you put in less water? How many times could you ask dad to retrieve the rocket from the roof before he really blew his stack? In our youth, little did we know we had a piece of science in our hands. To us, it was just a toy, an afternoon diversion. But a diversion such as this provides a perfect way to catch a student's interest. It's a toy, it's fun-but wait, it's also science, it's also chemistry.National Chemistry Week (NCW) 2005 brings the theme "The Joy of Toys". As has been done with past NCW themes (1), this annotated bibliography collects the best that past issues of JCE have to offer for use with this year's National Chemistry Week. Each item has been characterized as an activity, demonstration, experiment, informational, or software/video item; several fit more than one classification. The most recent articles are listed first. An indication of the levels the article may serve are included. Articles that appeared adaptable to other levels, but not designed explicitly for those levels, are labeled "poss. h.s." "poss. elem.", and so forth. Since all references are to Journal articles, they appear in abbreviated form, including only year, volume, page.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
