Floating Squares (GCMP) David M. Whisnant
Floating Squares: this is a resource in the collection "General Chemistry Multimedia Problems". In this problem we will coat a piece of notecard with graphite (from pencil lead). We then will float the piece in two beakers containing water and a second solvent. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.

Copoly; A Tool for Understanding Copolymerization and Monomer Sequence Distribution of Copolymers Massoud Miri, Juan A. Morales-Tirado
The study of the composition and monomer sequence distribution of binary copolymers is often complicated because of the many definitions of representative properties for the sequence distribution, the numerous calculations required, and occasionally the abstract treatment of the statistical processes describing the copolymer formation. Copoly resolves these issues with a user-friendly, highly visual interface to perform all calculations. Using Microsoft Excel and Word, Copoly is compatible with Windows and Mac OS. In Copoly the students enter up to five independent data parameters using the Data Input Window, and immediately see the results. To obtain diagrams for a copolymerization obeying a second-order Markovian process, the fraction of one monomer, A, and the reactivity ratios, rA, rB, rA´ and rB´ need to be entered; for a first-order Markovian process only the first three of these are required. For a Bernoullian- or zeroth-order Markovian process only A and rA are required. The results are displayed on separate sheets labeled: 1. Copolymerization Diagrams, 2. Dyads and Triads, 3. Sequence Length Distribution, 4. Simulated Copolymer Design, and 5. Summary.

Molecular Models of Polymers Used in Sports Equipment William F. Coleman
In keeping with the 2008 National Chemistry Week theme of Having a Ball with Chemistry, the Featured Molecules this month are a number of monomers and their associated polymers taken from a paper by Sandy Van Natta and John P. Williams on polymers used in making equipment for a variety of high-impact sports (1). The molecules provide students with an introduction to an important area of applied chemistry and also enable them to examine complex structures using the models they have seen applied to small molecules.It is certainly instructive for students to build small polymer fragments using molecular model kits. Holding a model of n-decane, for example, and twisting it in various ways, provides real insight into the multiplicity of conformations available to supermolecules of polyethylene. Computer-based 3-dimensional structure drawing and visualization programs make it possible to construct large oligomers of known polymers and to begin to explore structural properties of new systems. Two such programs, free for academic use, are DSVisualizer and ArgusLab (2). DSVisualizer includes a useful set of tools for building and viewing structures and a clean geometry option that applies a Dreiding-like force field. ArgusLab adds the ability to perform both molecular mechanics and semi-empirical geometry optimization and to display various molecular surfaces. Using ArgusLab, or a similar program, students can explore the relative energies of various conformations of the substances they have built electronically. Students who are being introduced to molecular modeling and the use of more sophisticated software can easily explore the effects of the modeling and convergence parameters on the stable structures that are found, and can begin to explore the difference between global and local minima on a molecular potential energy surface. Using the conformational search program in HyperChem 7.5 on a tetramer of vinyl chloride (terminated with H; of SRRS stereochemistry; only CCCC torsions varied), approximately half of the 500 structures examined fell within 6 kcal/mol of the lowest energy structure (3). This number would increase significantly if other torsion angles were included.The use of computational software allows us to introduce students in introductory chemistry to the idea of multiple conformations, which is so important in biochemistry and much of organic chemistry. In teaching ideas behind conformational stability care should be taken when attributing conformational stability solely to non-bonded repulsions between peripheral atoms on adjacent carbon atoms. Weinhold and co-workers have recently presented strong evidence that the stability of the staggered conformer of ethane relative to the eclipsed form arises from more favorable interactions of C-H sigma bonding orbitals on adjacent carbons (4). The multiplicity of such interactions could well be responsible for conformational stability in more complex systems. Any discussion of conformational stability should also introduce students to the ultimate conformational problem, the folding of proteins and to the Folding@home project (5).

Connected Chemistry Mike Stieff
Connected Chemistry, a novel learning environment for teaching chemistry, is appropriate for use in both high school and undergraduate chemistry classrooms. Connected Chemistry comprises several molecular simulations designed to enable instructors to teach chemistry using the perspective of emergent phenomena. That is, it allows students to see observed macro-level chemical phenomena, like many other scientific phenomena, as resultant from the interactions of many individual agents on a micro-level. This perspective is especially appropriate to the study of chemistry where the interactions between multitudes of molecules on the atomic level give rise to the macro-level concepts that students study in the classroom. Connected Chemistry comprises molecular simulations embedded in the NetLogo modeling software (1). The collection contains several predesigned simulations of closed chemical systems to teach specific chemistry concepts. Currently, Connected Chemistry contains models for teaching Brønsted Lowry acid base theory, enzyme kinetics, radical polymerization, buffer chemistry, kinetics, chemical equilibrium, and crystallization. Instructors and students can individually tailor the predesigned simulations or generate new simulations as they are needed in the context of a particular lesson, classroom, or department.
