An upper-division undergraduate laboratory experiment is described that explores the structure/function relationship of protein domains, namely leucine zippers, through a molecular graphics computer program and physical models fabricated by 3D printing. By generating solvent accessible surfaces and color-coding hydrophobic, basic, and acidic amino…

Describes the use of computer-assisted graphical displays in experiments to determine the order and activation energy for a chemical reaction. (MLH)

Described is a physical pendulum experiment with variable pivot as an example of maximizing computer benefits in laboratory interfacing. The laboratory procedures using spreadsheet graphics package are discussed. A diagram of the pendulum, basic formulas, and theoretical curve is provided. (YP)

Introduced is a unique generation method of Fourier series requiring simple mathematical skills and using computer programs. Discusses Fourier synthesis by microcomputer, and Fourier analysis with simple equipment. Shown are a circuit diagram, computer programs, monitor displays and tables of data. (YP)
