Educ. 1995, 72, 51) in which the authors are intending to explain several properties of metals, its ions and compounds from activity series of metals (derived from reactions with water/steam and dilute acids), the following observations might be of interest for those having decided to use this article in the class: 1. As quite simple arguments are used, statements and conclusions should be regarded as rough guides subjected to numerous exceptions. For example, in remembering the order of the series it is stated: "2. The increase in activity of metals down a group is explained...". However, what about Zn, Cd, Hg, to mention a familiar group? If a such statement has to be made I suggest a refinement such as "in groups 1 to 3" or "most active" accompanying to metals. 2. The information included in tables should be handled with care. For example, the presence and position of aluminium carbonate in Tables 4 and 5 induces to think that this is a common carbonate, also more resistant to heat than those of Zn, Fe, or Cu; in Table 6 (properties of metals....) the inclusion of I 2 solution is inappropriate, and the color blue associated to hydrated copper(II) together with the green to Cu 2+ is confusing. I suggest removing from these tables aluminium carbonate, I 2 solution, and hydrated copper(II), moving Cu 2+ to the position of this last.

He asserts that teaching the students to write well provides them a powerful thinking and learning tool. Another reason is to train the students to become more efficient spokespersons for science. The opinion of Antonine Lavoisier, who states, "It is impossible to dissociate language from science or science from language.... To call forth a concept a word is needed" is also cited.

The presentation is part of a larger course project which includes consideration of what traits mark good writing and good speaking that students can emulate. Evidence and observations show that this new format yields improved presentations, enhanced student engagement, and deeper learning.

Introdllction The number of KekulC valence structures K for conjugated hydrocarbons is an important structural parameter [l-3]. In the early days of organic quantum chemistry, it was already recognized that K represents a measure of molecular stability (see, for example, Ref. 4). For example, anthracene and phenanthrene (with K = 4 and 5, respectively) illustrate qualitatively that molecules with greater K have greater aromatic stability. It has also been suggested that 1ogK is proportional to the molecular resonance energy (RE) [5]. The parameter K is of interest in many theoretical studies of conjugated systems, e.g. for calculation of Pauling bond orders [6,7] or for the conjugated circuit approach to molecular RE [8,9]. There are a number of methods available for counting KekulC structures [ 1,2, lo]. However, there is also continuing interest in simple schemes for finding K [l l-191. We are particularly interested in algorithms that have simplicity and

This anomalously fast dephasing is explained in terms of a new theory which takes into account the two level systems structure of glasses and softon-phonon scattering involving very low frequency phonons. As a result, the high temperature limit for the scattering where the dephasing frequency is linear in T occurs at temperatures of only a few Kelvin.
