Presents numerous questions concerning transportation systems, energy consumption, noise, air pollution and other transportation oriented topics. Solutions are provided using undergraduate pre-calculus mathematics. (CP)

Presented is a simplification of an undergraduate relativistic mechanics problem concerning the visual appearance of a rapidly moving sphere as viewed from various angles. (CP)

Provides a table showing average power consumption rates for many home appliances. With this, a variety of student activities dealing with energy consumption are suggested. (CP)

Two groups of fourth graders performed a science activity. The treatment group first watched a filmed explanation of the activity by selected students from the class; the control group did not watch the film. The treatment group generated significantly more positive behaviors and less negative behaviors in the activity. (MLH)

Describes a laboratory experiment that begins with a discussion of the fermentation process, the steps of winemaking, the types of wines that can be produced, and the differences between wines. Outlines the procedure for making red wine in the laboratory and describes other types of wine that can be produced. (GS)

Describes an attempt to incorporate research into laboratory work in an introductory ecology class and a senior seminar. The investigation involves the examination of rhythms of food consumption and circadian activities in humans. (GS)

Presents five experiments in which the unknowns for analysis are prepared by the students themselves, the analysis forming an essential part of the investigation. (MLH)

Describes experiments for the undergraduate organic chemistry laboratory which demonstrate reactions and syntheses that involve free - radical intermediates. (MLH)

Describes the use of pieces of equipment such as the Oxygen Temperature Probe (OTB) commonly used by fisherman, for research field trips. The instrument can be used in classroom experiments as well. Other equipment described includes the electronic thermometer and oxygen monitor. (EB)

Describes how to construct an isothermal calorimeter and lists typical results of a displacement reaction using zinc. (LS)

Construction of a laboratory area suitable for laser experiments and the creation of holograms is described. (CP)

Describes features of agglutinin research utilizing the jack bean and suggests similar experiments for biology students that utilize more familiar plants. (LS)

Describes a series of activities for demonstrating the conditions necessary for burning (fuel, oxygen and temperature) plus several related phenomena. (CP)
