An innovative teaching and research partnership was developed in collaboration with public high school chemistry teachers from the Talawanda (Ohio) School District and faculty, staff, and students from Miami University. With the involvement of high school teachers, chemistry faculty, postdoctoral associates, and several graduate and undergraduate…

Some simple copper compounds have unusual crystal structures. Cu[subscript 3]N is cubic with N atoms at centers of octahedra formed by 6 Cu atoms. Cu[subscript 2]O (cuprite) is also cubic; O atoms are in tetrahedra formed by 4 Cu atoms. These tetrahedra are linked by sharing vertices forming two independent networks without linkages between them.…

The importance of educating people to live in our increasingly science- and technology-rich world is well established. Many institutions require students to take one or more courses in science. Some nonscience majors are intrigued by this opportunity, while others are less inclined to take science classes. This project used a mixed-methods…

The use of recorded music to add interest to a variety of lecture topics is described. Topics include the periodic table, the formation of ionic compounds, thermodynamics, carbohydrates, nuclear chemistry, and qualitative analysis. (Contains 1 note.)

A classroom activity is presented in which students are challenged to find matches between the United States two-letter postal abbreviations for states and chemical element symbols. The activity aims to lessen negative apprehensions students might have when the periodic table of the elements with its more than 100 combinations of letters is first…

This paper provides nine short chemically based puzzles or problems extensible for use with students from middle school to college. Some of these will strengthen students' recognition of individual elements and element names. Others require students to focus on the salient properties of given chemical elements.

The periodic table and the periodic system are central to chemistry and thus to many introductory chemistry courses. A number of existing activities use various data sets to model the development process for the periodic table. This paper describes an image arrangement computer program developed to mimic a paper-based card sorting periodic table…

Several case studies from popular television medical dramas are described for use in an undergraduate biochemistry course. These cases, which illustrate fundamental principles of biochemistry, are used as the basis for problems that can be discussed further in small groups. Medical cases provide an interesting context for biochemistry with video…

Students of organic chemistry traditionally make 3 x 5 in. flash cards to assist learning nomenclature, structures, and reactions. Advances in educational technology have enabled flash cards to be viewed on computers, offering an endless array of drilling and feedback for students. The current generation of students is less inclined to use…

Two systems were evaluated for drawing Lewis structures of period 2 and 3 non-metallic compounds: the octet rule and minimization of formal charge. The test set of molecules consisted of the oxides, halides, oxohalides, oxoanions, and oxoacids of B, N, O, F, Al, P, S, and Cl. Bond orders were quantified using experimental data, including bond…

Two commercial self-heating food products have been used to apply chemical concepts such as stoichiometry, enthalpies of reactions and solutions, and heat transfer in a classroom activity. These products are the self-heating beverages sold in Europe and the Meals, Ready to Eat or MREs used primarily by the military in the United States. The main…

Any student that has spent time in the kitchen knows that hot vegetable oil will pop and spatter violently after coming into contact with water such as that on the surface of foods (meat, fish, potatoes, etc.). This well-known effect can be used as an instructional resource to promote cooperative, active, and inquiry-based learning about central…

Potassium dioxide, KO[subscript 2], (potassium superoxide) is an important compound owing to its ability to react with carbon dioxide to produce oxygen. This unique ability is employed to design rebreathing devices for submarines, space vehicles, and space suits. "Rebreathers" for firefighters and miners have also been designed using potassium…

Studies on student learning during primary- and secondary-school course-related field trip activities have shown lasting cognitive and socio-cultural effects. However, fewer studies have investigated the potential benefits of incorporating field trip activities into post-secondary education. The curriculum in a first-year university chemistry…

A new interdisciplinary, introductory science course was offered for the first time during the 2007-2008 school year. The purpose of the course is to introduce students to the idea of working at the intersections of biology, chemistry, and physics and to recognize interconnections between the disciplines. Interdisciplinary laboratories are a key…
