Abstract: A computer system includes a data storage device and a first computer processor in communication with the data storage device. At least one input device and a first program memory are in communication with the first computer processor. The computer system also includes a second computer processor in communication with the first computer processor. At least one other input device, a display device and a second program memory are in communication with the second computer processor. The first computer processor produces a random sampling of files from a set of files that match a set of parameters defined using the input device coupled to the first computer processor. The random sampling of files is displayed on the display device coupled to the second computer processor.

Abstract: What is disclosed herein relates to a method of educating students, such as high school or introductory college students, in the field of chemical sciences. More specifically, the method is a means of reducing barriers to active learning in a chemistry classroom through the use of interactive kits and instruction.

Abstract: An improved method for students to carry out and observe chemical reactions by mixing a fluid reactant with a reactive component to produce a reaction product. The improvement is the provision of a package fabricated of upper and lower sheet material defining at least a first closed chamber containing a first fluid reactant and an adjacent second closed chamber containing a reactive component, the package formed by sealing the upper sheet material to the lower sheet material at the periphery of the chambers so that when the first chamber is pressed, then the first fluid reactant will break the seal between the first and second chambers and flow into the second chamber to react with the reactive component in the second chamber to produce an observable reaction product or condition.
