Various microcomputer-generated astronomy graphs are presented, including those of constellations and planetary motions. Graphs were produced on a computer-driver plotter and then reproduced for class use. Copies of the programs that produced the graphs are available from the author. (Author/JN)

Describes several games in which physics principles are demonstrated using students. These include Pirates Treasure Game (vectors), Three-Meter Dash (kinematics), Knee-Bend Game (energy and power), Wave Game, Reaction Kinematics, Statics-People Pyramids, and games demonstrating nuclear reactions, collisions, electrons in a wire, close packing, and…

In a previous article in this journal (Vol. 17, p358, 1979), a wet-bulb depression table was recommended for two simple experiments to determine relative humidity. However, the use of a graph is suggested because it gives the relative humidity directly from the wet and dry bulb readings. (JN)

Describes and analyzes several problems physics teaching assistants (TA) may encounter, offering possible solutions to the problems. Areas addressed include administrative details of the lab/recitation and its relation to the lecture, objectives of lab/recitation sessions, goals for the recitation/lab TA, grading procedures, and others.

A thermodynamic analysis of the properties of otto/diesel engines during the time they operate with open chambers illustrates applicability of thermodynamics to real systems, demonstrates how delivered power is controlled, and explains the source of air pollution in terms of thermodynamic laws. (Author/JN)

Discusses why interference effects cannot be seen with a thick film, starting with a review of the origin of interference patterns in thin films. Considers properties of materials in films, properties of the light source, and the nature of light. (JN)

Reasons for studying human genetics are discussed. These include philosophical reasons, reasons of health, and social reasons. While content, interpretation, and emphasis of human genetics study will vary depending upon schools, teachers, and developmental stages of students, it is suggested that teachers address these three domains. (Author/JN)

Information from scientific journals on the biology of skin color is discussed. Major areas addressed include: (1) biology of melanin, melanocytes, and melanosomes; (2) melanosome and human diversity; (3) genetics of skin color; and (4) skin color, geography, and natural selection. (JN)

Although most waves studied by students satisfy the linear equation, particle physicists have become interested in nonlinear waves--those not satisfying the superposition principle. A mechanical wave system, satisfying the sine-Gordon equation, can be constructed using a modified transverse wave system to demonstrate nonlinear wave-particle…

Highlights current activities of the NSF-funded Project SERAPHIM, including a report on the August 1982 Biennial Conference, development of procedures/criteria for evaluating microcomputer software, software evaluation, and preparation of a list of available software. A list of materials available from the project and SERAPHIM Program Contest…

Discusses reasons for including industrial chemistry into the college chemistry curriculum. One reason is that chemistry students, and students generally, should appreciate the role of the chemical industry in our history, economy, and culture. Problems associated with teaching industrial chemistry are addressed and a British university/industry…

Discusses principles of a particular approach in teaching elementary kinetics of polymerization. Although the treatment discussed is more difficult for students to grasp, problems may be reduced using a computer program. The program, written in Applesoft Basic, is available from the author together with sample output. (JN)

Testing the accuracy of college teachers' assumptions of topics taught in high school chemistry, it was found that high school chemistry teachers do not agree on what topics should be included in their courses and that college chemistry teachers are incorrect in their assumptions of what is taught in high school. (Author/JN)

Suggests alternatives for benzene, carbon tetrachloride, and chloroform and offers safety precautions when these solvents must be used. (JN)

Reports results of two-part survey on organization of chemical libraries at the college and departmental levels. Includes library configuration, size of collections, hours/service/staff, departmental reading rooms, and instruction in chemical literature based on questionnaires returned by 149 libraries and 144 department chairpersons.
