This technology report alerts upper-division undergraduate chemistry faculty and lecturers to the use of Texas Instruments emulators as virtual graphing calculators. These may be used in multimedia lectures to instruct students on the use of their graphing calculators to obtain solutions to complex chemical problems. (Contains 1 figure.)

The use of Calculator-Based Laboratory (CBL) technology, the graphing calculator, and the cooling and heating of water to model the behavior of consecutive first-order reactions is presented, where B is the reactant, I is the intermediate, and P is the product for an in-class demonstration. The activity demonstrates the spontaneous and consecutive…

A combination of graphical thinking with chemical and physical theories in the classroom is encouraged by using the Calculator-Based Laboratory System (CBL) with a temperature sensor and graphing calculator. The theory of first-order kinetics is logically explained with the aid of the cooling or heating of the metal bead of the CBL's temperature…

Describes an adaptation of the chemistry of lightsticks to use the calculator-based laboratory (CBL) interface, a TI-82/83 graphing calculator, and an easily manufactured wooden block as the support system. (CCM)

Describes the different types of scientific calculators and explains how graphic calculators can apply to chemical problems. (Contains 19 references.) (YDS)

A demonstration, which shows that the graphing calculation can greatly supplement the computer and often eliminates the need for computers and science, is given. The graphic calculator is a handheld computer, more powerful than most sophisticated computer of 25 years ago.

Describes the use of calculator based laboratory (CBL) technology in monitoring the process of chemical reactions. Explains the estimation of infinity readings and criteria to choose t values. (YDS)

The backdrop of the calculus reform movement created a fertile movement for the creation of overlap between general chemistry and precalculus as many of the goals emphasized key concepts from the chemistry lab. By using the graphing calculator in both precalculus and chemistry laboratory enhanced the students' comfort and competence with the…

Describes four activities that use graphing calculators to model nuclear-decay phenomena. Students ultimately develop a notion about the radioactive waste produced by nuclear fission. These activities are in line with national educational standards and allow for the integration of science and mathematics. Contains 13 references. (Author/WRM)

Describes the use of Calculator-Based Laboratory (CBL) technology and a projectable TI-83 graphing calculator to demonstrate the kinetic behavior of a complex reaction. Explains how the CBL is used to review first-order reactions and the graphing calculator is used to determine the rate constants for a series of consecutive first-order reactions.…

Describes the ChemKits initiative devised by private colleges in Kansas to help high school science teachers meet their needs for laboratory equipment. Discusses conclusions from three years of running the ChemKits teacher-education program. (WRM)
