One of the challenges in teaching a hybrid Basic Course in Communication is the wide variety of topics that can be covered in one semester. Two basic course instructors have found that their recently opened Basic Course computer lab gave them the opportunity to develop interdisciplinary assignments to help more efficiently address various…

It is very important to provide a safe learning environment for students while engaging them in investigative and observational hands-on science activities. This teacher's guide provides information on safety rules and regulations in a narrative style while discussing both self-contained classroom teachers and science specialists in the elementary…

The University of Georgia (UGA) biosafety program was initiated in response to requirements for recombinant DNA experiments rather than laboratory-acquired infections. This and other environmental safety programs at UGA are described, considering three of the four recognized levels of biocontainment. A fire extinguisher inspection computer program…

Methods for organizing and storing chemicals in teaching laboratories and preparation rooms are given, emphasizing storing and handling of flammable liquids. Two appendices are given: (1) flash points and autoignition temperatures of common flammable liquids; (2) content of a kit, with instructions, for cleaning up spills of flammable liquids. (JN)

Describes an experiment for the use of a tilted plane as a two-dimensional uniform gravitational field to demonstrate the motion of projectiles, to determine the fundamental laws of mechanics, or to study the focusing properties of the uniform field. (SK)

This experiment demonstrates the reduction of inorganic sulfate to sulfide in the pore water of estuarine muds. Procedures involve the incubation of mud samples for varying amounts of time followed by gravimetric determination. (Author/SA)

Some goals and activities are suggested to create a positive image of the language laboratory. The ambience, hours of operation, range of audio and visual materials, interdepartmental activities, tape and photocopying services, and extracurricular activities must be designed with the needs of the student, the department, the university, and the…

The laboratory curriculum of an introductory physical geology course which emphasizes a peer-learning approach is discussed. (Author/SA)

Presents a session by session description of a "meats" class, which is offered to high school students (9-week period) and adults (8-week period). The classes cover identification of cuts (beef, sheep, hogs, and veal; grades and grading of live animals and carcasses; economics of butchering and cutting your own meat; actual slaughtering; and the…

At the introductory level, the computer provides an effective alternative to using animals for laboratory teaching. Computer software can simulate the operation of multiple organ systems. Advantages of software include alteration of variables that are not easily changed in vivo, repeated interventions, and cost-effective hands-on student access.…

Describes research that documents the falsification of laboratory results by chemistry and physics students. Discusses some factors that encourage students to fabricate results and why some students do not feel the need to falsify data. Contains 16 references. (DDR)

Improvements in the mechanism of the whirlybird used in the Science Curriculum Improvement Study (SCIS) unit "Subsystems and Variables" are presented. Variables which can be investigated using this device are discussed. An illustration of the improved device is provided. (CW)

The advantages of microchemistry in terms of economics and safety are discussed. A list of six companies known to supply apparatus and reagents for microscale experimentation is provided. (CW)

The interfacing of a physical pendulum to an Apple IIe computer and the physic instruction associated with it are discussed. Laboratory procedures, software commands, and computations used in this lesson are described. (CW)

Described is a simple technique to monitor air pollutants and to simulate some of the features of roadside canopies. Included are the procedures, directions for the assembly of the apparatus, and a discussion of typical results. Graphs of sample data are presented. (CW)
