The article authors, being the judges of the contest, analyze results of the former competition of teachers.

The Ancient Sea salt is a highly effective, and ecologically clean balneal remedy rich in magnesium, potassium, bromine, ferrum, and other vital elements for the wide use under the sanatorium, balneal and household conditions. Due to the state-of-the-art, highly effective technology, bischofite while being processed does not loose its high natural quality, due to which it becomes being able to meet competition of the imported bischofite supplied to the international market.

The 2011 Nobel Prize in Chemistry is awarded to the Israeli material engineer Dan Shechtman. The scientists is awarded "for the discovery of quasicrystals" and their structure research.

Associate Head of the Legal Department of the Administration of the All-Russian Trade Union of the Education is answering our readers’ questions.

Innovative valuation means are examined in the paper. They are recommended for estimating the results of learning of educational program in chemistry and correspond to the requirements of the Federal State Educational Standard. The criterion base of evaluation and the diagnosable indices for getting numeral characteristics of the school chemical education quality are proposed.

Starting from this academic year, teachers develop a theme planning in accordance with the Second Generation Russian Education Standards. The calendar theme applied before has been shaped as a working program, which foresees the specification of the chemistry academic education content, lesson types, the forms of controls, and the main modes of the academic activity of students.

The module technology in teaching is focused on the active academic activity of students, mastering methods of which contributes to the quick and qualitative digestion of the academic material content. The essence of the module teaching is for a student to reach certain goals of the academic and cognitive activity in the process with the module independently (or with a certain dosage of the assistance).

While preparing to take the Unified State Examination in chemistry, students are to assimilate the material about the properties of the metals of auxiliary groups, to examine their possible compounds, to come to know their nomenclature. Many chemical reactions in the solution happen with the forming of complex salts, for which metals are the basis. The synthesis of many kinds of medicine, vitamins, and biologically active additives is also connected with complex compounds. The 11th Form profile class lesson is dedicated to this theme.

As the experience approves, theme “The Salt Hydrolysis” is quite complicated to comprehend by students. The methods of studying the given theme are offered.

A resumptive lesson on the subject of “Water” is offered, at which students work in teams and individually, using cards with team and individual tasks.

The algorithm of Ionic Half-reaction Method application is considered at the example of the most commonly encountered oxidizers in chemistry tasks for school-leavers. Method of Ionic Half-reactions is a universal and has the evident advantages in comparison with Electron-balance method because it allows determining unidentified products (or even original substances) along with coefficients in the chemical equation. The modern technique of school-leaver training requires the compulsory knowledge Ionic Half-reaction Method.

The study of the “Enzymes” theme in the 10th Form course of chemistry provides and opportunity to generalize knowledge about catalysts and catalytic reactions, which students have mastered to collect by this time. Carrying out laboratory research work “The Properties of Enzymes” not only allows to broaden and generalize the students’ knowledge in chemistry, but provides the opportunity to establish interrelation of the material studied with the general biology course, to explain the reasons of the poisonous influence of the number of substances, which people encounter on in their everyday life, on the organism.

Chocolate is one of the most delicious and healthiest confectioneries the majority of peoples make use of. But whether the consumers know, what kind of chocolate is more delicious and healthier? The authors do their best to figure out, what kind of chocolate is more delicious and healthier.

The article tells about the first American chemists among women - Rachel Bodley and Rachel Lloyd. They were the first professors of chemistry among U.S. women, the first women - members of the American Chemical Society. The paper is also tells about Ellen Richards, who was the first American woman received the degree in a technical university. The descriptions of their biographies, advances in chemistry and other fields of human activity, Bodley’s contribution to the creation of the American Chemical Society, Lloyd’s merits in exploring the possibility of growing sugar beet in Nebraska, Richard’s contribution to solving environmental problems of Massachusetts and the development of scientific bases for household management are contained in the article. The information about women's higher education history in America and the first institutions of higher education for American women are also considered.

It is narrated about the nuclear model offered by the Russian scientist Peter Nickolaevich Lebedev.
