Students use a simple set up consisting of a coil of wire and a magnet to visualize induced EMF. First, students move a coil of wire near a magnet and observe the voltage that results. They then experiment with moving the wire, magnet, and a second, current carrying coil. Students connect the coil to a circuit and the current from the induced EMF charges a conductor.

Inorganic chemistry is concerned with the properties and reactivity of all chemical elements. Advanced interests focus on understanding the role of metals in biology and the environment, the design and properties of materials for energy and information technology, fundamental studies on the reactivity of main group and transition elements, and nanotechnology. Synthetic efforts are directed at hydrogen storage materials and thermoelectrics, catalysts for solar hydrogen generation, fullerenes and metal porphyrins, metal clusters and compounds with element-element bonds, as well as nanowires and nanoparticles.

This is an assessment tool used with inquiry labs. Each quarter we add another layer as follows: 1. First quarter we work intensely on the experimental design section. 2 . Second Quarter we add more and focus on organizing and interpreting data (Results Section) 3. Third quarter we hone skills in writing the conclusion section. 4. Fourth quarter students develop the critical thinking skills needed for writing and discussing errors and validity in the discussion section.

In this hands-on inquiry activity, students will design and construct an apparatus that will permit an egg to survive a nine foot fall. Students are given limited materials, so they must critically think about the design and improvise strategies during the building of the apparatus
This course uses reaction kinetics, batch reactor analysis, batch distillation, batch operations scheduling, safety analysis, and the ABACUSS process simulator to introduce process design and analysis techniques.

Presents and solves chemical engineering problems in an industrial context, with applications varying by semester. Emphasis on the integration of fundamental concepts with approaches of process design. Emphasis on problems that demand synthesis, economic analysis, and process design .This course introduces students to methods and background needed for the conceptual design of continuously operating chemical plants. Particular attention is paid to the use of process modeling tools such as Aspen that are used in industry and to problems of current interest. Each student team is assigned to evaluate and design a different technology and prepare a final design report. For spring 2006, the theme of the course is to design technologies for lowering the emissions of climatically active gases from processes that use coal as the primary fuel.

This activity seeks to have students model the process of science by recording quantitative and qualitative attributes of reactants and products in three separate experiments with the purpose of examining the relationship between the original reactant(s) to the final product(s). Students record the mass and volume of reactants and products and independently calculate mathematical relationships between the reactant(s) and product(s). They also record their observations of any physical changes that occur.
