21 Appendix 6 – New CHEM Course Overviews CHEM 131 Chemistry I – Fundamentals of General Chemistry (Semester # 1 lecture for non-majors) Chemistry is the study of matter and involves our entire environment, both the animate and inanimate worlds. Chemical topics range from those that are biological in nature to those involving basic physics. In an introductory chemistry course the goal is to learn something of the properties of everyday materials, to learn the language of chemistry, and to gain some facility in thinking like a chemist. The language of chemistry is learned the old-fashioned way by memorization and practice. The chemist's thought processes begin with careful observations, following which an attempt is made to fit these observations into a model that describes a set of similar observations and mathematical calculations are carried out in order to use quantitative observations in the prediction of other properties of matter. Particular attention will be given to bonding and the shapes of molecules since these matters play an important role in organic chemistry that is the subject of CHEM 231 and 241, the second and third semesters of the four-semester sequence for freshmen and sophomores. A student in CHEM 131 should memorize the names, symbols and definitions of the SI system of units of measurement of mass, length, time, temperature and amounts of substance along and units of volume and pressure derived from the SI system. The SI scaling prefixes (e.g., micro, mega) must be learned. To begin learning the chemist's language, memorize the names and symbols of elements 1-30 and Br, Kr, Rb, Sr, Ag, Sn, Sr, I, Xe, Cs, Ba, Au, Hg, Pb, Bi. In the first few weeks of this course the names and formulas of the common acids and bases will be learned along with the names, formulas, and charges of the common ions. The student will be responsible for knowing the names, formulas, and basic properties (especially the phase, gas, liquid, or solid) of the compounds dealt with in lab or discussed in lecture. READING: The attached syllabus gives a reading assignment for each week. Complete the reading before coming to lecture on Monday.

Elements, compounds and ions all have easily observed characteristic physical (color, state of matter, density, solubility in water and other solvents, electrical conductivity, hardness) and chemical (to react with water or oxygen in the air, to displace other chemical species from solution, to generate gases–recognized by the formation of bubbles or smells–when treated with acid) properties. When such species participate in a chemical reaction and undergo chemical change, the products generated have physical and chemical properties different from the starting materials and these properties are easily observed and characterized. Through observation, students can both create for themselves a data bank of personally defined information about properties unique to individual chemical species, which they will be likely to recall when later encountered, and recognize from changes in these observed properties when a chemical reaction occurs, as well as identify the newly formed chemical species. CHEM 132 laboratory is structured around this premise. It first emphasizes observation and measurement as the primary tools of the science, allowing students to construct their data banks of retrievable characteristic information. It then directs them to apply that information as in studies of series of traditional chemical reactions.

CHEM 147 includes a four-hour lab whereas CHEM 146 is a three-hour lab. Chemistry is the ultimate observational science. Elements, compounds and ions all have easily observed characteristic physical (color, state of matter, density, solubility in water and other solvents, electrical conductivity, hardness) and chemical (to react with water or oxygen in the air, to displace other chemical species from solution, to generate gases–recognized by the formation of bubbles or smells–when treated with acid) properties. When such species participate in a chemical reaction and undergo chemical change, the products generated have physical and chemical properties different from the starting materials, properties which are similarly easily observed and characterized. That means that through observation in the laboratory, students can create for themselves a personally defined data bank of likely-to-be-recalled properties unique to individual chemical species, only to later recognize--from observation of changes in these properties--when a chemical reaction has occurred, and the identity of newly formed chemical species. This is a central premise around which CHEM 147 Laboratory is structured. Initially, the exercises emphasize observation and measurement as the primary tools of the science with which students will construct their data bank of retrievable characteristic information. The course then leads students to apply that information to traditional chemical processes involved in the analysis of representative inorganic compounds, as well as the synthesis of others. The sequence of experiments is structured so that each subsequent exercise builds on the experience of the last, expanding the understanding of the fundamental chemical bases for earlier observations and their implication in subsequent applications. The approach of the majors course is more quantitative than that in the non-majors lab and explores techniques not introduced in CHEM1 Lab.

These topics will be treated in the context of the lecturer’s personal research interest. The defined content, presented in all sections of CHEM 271, will include electrochemistry, chemical kinetics and an introduction to thermodynamics with emphasis on the application of free energy functions. The contextual material may be drawn from biochemistry, analytical chemistry, physical chemistry, inorganic chemistry, or materials chemistry depending upon the lecturer’s special interests. Chemistry, 4th edition, by McMurry and Fay will be the text for the defined content. Reading and homework assignments are given below. As in CHEM 131, homework and quizzes will be carried out on-line. In addition, the student can anticipate reading and homework assignments specific to the research topic chosen by the lecturer.

Ninfa and Ballou, Fundamental Laboratory Approaches for Biochemistry & Biotechnology CHEM 272 laboratory is intended as the principle laboratory experience students studying Chemistry and Biochemistry will have in Analytical Chemistry, a field dedicated to the chemical characterization of matter, both qualitative and quantitative. In that regard, it will cover traditional topics in analytical chemistry: precision and accuracy in measurement; statistical analysis of data and defining acceptable error limits; traditional analytical techniques such as acid-base and oxidation-reduction titration; chromatography techniques to separate molecules for analysis; and use of spectrophotometric and electrochemical instrumentation to analyze those materials. However, the design of CHEM 272 recognizes the biological/biochemical interests of a majority of the students who enroll and the molecules analyzed will be those encountered in biochemical systems and of importance in biological processes. The specific analytical and separation techniques employed and procedures explored are those most frequently encountered in the biochemistry laboratory. The course is a co-requisite to CHEM 271 and should be viewed as an appropriate accompaniment to the first lecture course in Biochemistry, BCHM 461.

We have reviewed the course changes and see no problem with this change. We plan to advise our advisors and let our students know. I am told that this will not affect our PT students as a second chemistry is no longer needed. We are hoping that the pre-med advisor in L & S will give us some guidance for our pre-med students.

Both ENGR and CHEM will monitor seats over the summer to make sure that there is sufficient space). CHEM 136, though, will remain restricted to engineering majors.
