High school students should have a greater understanding of global environmental issues. This can be accomplished by using environmentally-relevant examples to teach high school chemistry. Appropriate demonstrations and laboratory experiments that illustrate these topics are suggested. To incorporate additional environmental chemistry in die secondary curriculum, help from environmental scientists will be needed. 

Using Environmental Examples to Teach About Acids. Acid-base reactions are usually presented to secondary students as examples of aqueous equilibrium (2). In their study of acids and bases, students are expected to master the characteristic properties and reactions. They are taught to test the acidity of solutions, identify familiar acids and label them as strong or weak. The ionic dissociation of water, the pH scale and some common reactions of acids are also included in high school chemistry. All of these topics may be illustrated with examples related to acid deposition (5). A lesson plan is presented in Table I. 

RELATIVITY IN ILLUSTRATIONS, Jacob T. Schwartz. Clear non-technical treatment makes relativity more accessible than ever before. Over 60 drawings illustrate concepts more clearly than text alone. Only high school geometry needed. Bibliography. 128pp. 6b x 9. 25965-X Pa. 5.95... 

In the end, with the antipathy of most of the women science teachers, domestic science ceased to be an acceptable alternative science subject for girls. As illustration, Sutton High School closed its domestic science department in 1916.59 By 1918, domestic science had been relegated to a low-status nonacademic subject.60 The high-school debate was over.

Incidentally, at this point you may recall from your high school days a rule about always expressing your thesis in one sentence. Writing teachers often insist on this rule to help you avoid the double-assertion problem just illustrated. Although not all essays have one-sentence theses, many do, and it s a good habit to strive for in this early stage of your writing. 

In terms of a laboratory and / or in-class demonstration setting, the emission spectra of gas tubes with hydrogen, sodium, neon, or mercury may be viewed with inexpensive diffraction gratings to illustrate identification of elements. A demonstration with flame tests of salts can further Illustrate the basis of Bohr s atomic theory. Additionally, flame tests are often employed as a part of qualitative inorganic laboratory procedures for the determination of various cations. Such lab activities or demonstrations are appropriate for middle school, high school, and undergraduate chemistry courses. 

The astrophysical version could be used for high school physics and astronomy classes for search and discover activities, in a simplified form. For elementary school, the concept of space chemistry can be illustrated by the many different types of species observed, such as N2H, CCH, HC5N. Atomic emission from hydrogen Ha lines also observed at radio telescopes can be used to exemplify the Bohr atom. 

In 1989, a new initiative was tried. The Northeastern Ohio Educators Association (NEOEA) always holds an in-service day in October. BP Research decided to sponsor a symposium for junior and senior high school science teachers called "Science and Technology At Work In Industry." One of the main purposes was to illustrate to the teachers how the scientific principles they taught in the schools were put to use in industry. Topics included energy, analytical problem solving, environmental concerns, and artificial intelligence. The symposium was very well-received and it was repeated in 1990. 

The first two reactions we discussed in this chapter were the anodic and cathodic reactions for steel in concrete. The terms anode and cathode come from electrochemistry which is the study of the chemistry of electrical cells. Figure 2.5 is a basic Daniell cell which is used at high school to illustrate how chemical reactions produce electricity. The cell is composed of two half cells , copper in copper sulphate and zinc in zinc sulphate. The total voltage of the cell is determined by the metals used and by the nature and composition of the solutions. What is happening is that in each half cell the metal is dissolving and ions are precipitating, that is. 

Strains of S. aureus resistant to methicillin are common in hospitals and these bacteria are increasingly being found in non-hospital settings such as locker rooms. Minor scrapes incurred by high school football players and wrestlers have become infected and have led to amputation of limbs and even death in very short periods of time. The problem has become so serious that it was the focus of an article in Sports Illustrated in the spring of 2005. 

All the cases described in this chapter also suggest a contribution to a perception of the relevance of chemistry education among the learners and a better awareness of environmental and sustainability issues, as also discussed by Mandler et al. The studies also described contributions to general skill development, e.g., how to react to politics, media or consumer choices. These claims will be illustrated by a quote from one student from Israel and three from Germany all after having learned about biodiesel in the first year of the senior high school cycle ...
