1 Chemistry 213: Principles of Chemistry II (Lecture and Lab - 4 s.h.) The purpose of this general chemistry course is to provide students with the knowledge to understand and appreciate our world/universe from the viewpoint of chemistry principles and with the tools to apply the methods of scientific inquiry (along with the chemistry knowledge) toward an enhanced understanding of the natural world. The studies of chemistry involve the study of matter and the transformations it undergoes utilizing the scientific method of discovery, experiment, and conclusion. The applications of these studies will provide students with an enhanced understanding of such everyday applications as the chemical reactions in the living cell, the common chemicals used in our homes, and the connection between microscopic structure and macroscopic properties. Catalog Description: A continuation of Principles of Chemistry I. An in-depth study of the principles of chemistry including kinetics, equilibrium, acid-base theory, and elctrochemistry. Organic and inorganic examples are used when appropriate throughout the course. Laboratory and lecture are coordinated. Prerequisite: CHEM 212 or equivalent. Meets the Natural Science requirement under the Arts & Sciences Core of the University Studies program. Offered yearly. This course includes requirements and learning activities that promote students' abilities to... a. understand how scientists approach and solve problems in the natural sciences; Requirements: Students are taught the scientific method. Many different real world problems are presented and students are expected to learn how to apply the scientific method and the principles of chemistry to solving and understanding chemistry related phenomena. Activities: Students are provided with many opportunities to apply the chemistry concepts. Activities include in-class/out-of-class problem solving sessions, one-on-one tutorials, instructor-led and group discussions, and laboratory exercises. A particular example is the determination of the equilibrium constant of an iron thiocyanate complex where a standard curve is used to evaluate and determine the equilibrium constant. b. apply those methods to solve problems that arise in the natural sciences; Requirements: Students are expected to apply the methods and the techniques of problem solving in many varieties of science and chemistry phenomena. Activities: Students apply various techniques, such as pattern recognition and trend analysis, to solve many problems during laboratories and class assignments. A particular example involves the study of water. Students are asked to bring in water samples from home. In the laboratory the ph is measured and the buffering capacity is determined. The water sample sources and results from the class are compiled and discussed in lecture. The class discussion centers on the geology of the different water source locations, the measured buffering capacity, and the concomitant acid rain susceptibility of the different regions. In the laptop laboratory sections, students develop an experiment, carry out that experiment and report the results in a written report and in a oral presentation as a final lab project. c. use inductive reasoning, mathematics, or statistics to solve problems in natural science; Requirements: Solving problems in chemistry related phenomena invariably involve the use of inductive reasoning and mathematics (and/or statistics). Students are presented with many problems and laboratory exercises that require these skills in solving the problems. Activities: Activities such as homework assignments, in-class exercises, and laboratory experiments and reports require inductive reasoning and mathematical skills.

2 d. engage in independent and collaborative learning; Requirements: Students are expected to work in pairs or small groups to collect several experimental data sets. Although they are encouraged to discuss data analysis and interpretation in a collaborative manner, students are required to hand in reports that are written in an independent manner. Activities: Students work in pairs or small groups in data collection. Analysis can be done collaboratively but laboratory reports require individual input. Additional collaborative learning is accomplished when all students in a class share and analyze the data from the entire class. Some lecture activities include group discussions on conceptual applications to real-world problems in natural science. Often students are given a problem in class and are asked to solve the problem in a group setting. e. identify, find, and use the tools of information science as it relates to natural science; Requirements: Students are required to employ many tools of information science, such as searching scientific and chemistry-specific journals or references in both non-electronic and electronic formats, to elucidate, decipher and solve problems in natural science. Activities: Many laboratory exercises require students to search for relevant information on physical and chemical properties before, during and after the experiments, for comparison with experimental data. Usage of such tools of information science enhances the students ability in investigative techniques in different areas of natural science. Non-electronic and electronic resources are available readily. A specific example involves a research paper on an assigned topic like a chemical element or chemist utilizing electronic sources. f. critically evaluate both source and content of scientific information; and Requirements: Laboratory experiments and lecture assignments are designed for critical evaluation by students. Chemical concepts are tested against experimental data collected by students. Activities: Included with laboratory exercises and class assignments, students are assessed based on their performance on quizzes, tests, and laboratory reports. These activities are designed to allow students the opportunity to critically evaluate both source and content of chemical information. One specific assignment asks the students to search the popular press for articles related to chemistry and to write a description of the article evaluating its validity and relation to chemistry. Also, in the laboratory, students often compare their data to literature values, thus, evaluating their data. g. recognize and correct scientific misconceptions. Requirements: Many chemical concepts (such as electronic and molecular structures) are difficult and abstract. Students are taught to recognize misconceptions in chemical concepts and how to revise and correct with proper perspectives. Activities: Laboratory experiments such as determination of atomic and molecular spectra give students the opportunity to critically evaluate and demystify chemical misconceptions in atomic and molecular structures. The popular press assignment mentioned in f. above sometimes exemplifies scientific misconceptions that the general public promotes. This course also satisfies the laboratory requirement in the Natural Sciences and will additionally provide students with the opportunity to practice scientific inquiry through hands-on investigations and to analyze and report the results of those investigations. Requirements: Chemistry is a laboratory science that requires active learning. As such, students are required to perform and complete weekly laboratory exercises. This laboratory requirement will give students practical and hands-on experience of basic chemical analysis, application of chemistry

3 concepts, and the general understanding of the scientific method. Activities: The weekly laboratory exercises include hands-on activities such as: pre-lab studies and preparations (reviewing and searching of relevant concepts and information before doing the actual experiments), the learning, practicing, and performance of experimental techniques, collecting data with modern instrumentation, analyzing results, interpreting or discussing data (relative to models), making conclusions, and complementing these activities with the writing of a laboratory report. These hands-on investigations will give students an enhanced appreciation and understanding of the chemical universe.
