Discusses the mechanics of how an actual oil reservoir works and provides some technical background in physics. An experiment which simulates an oil reservoir and demonstrates quantitatively all the basic concepts of oil reservoir rock properties is also presented. (HM)

Presents nine selected physics notes which could be used in selected physics courses. Each includes the name of the author and a description of activities suggested. (HM)

Provides descriptions of a range of resources and methods that can be used to produce metals such as titanium, vanadium, chromium, manganese, iron, and molybdenum. Details on equipment and safety precautions are also outlined. (DDR)

Explains a series of experiments that enable students to discover the internal and external structure of the vanilla pod, isolate the chemical constituents of the pod, identify vanillin in the pod extract, and compare extracts across varieties of vanilla. (DDR)

Presents experiments which show that in electrostatics there are logical reasons for describing charged materials as positive or negative. Indicates that static and current electricity are not separate areas of physics. Diagrams of experiments and circuits are included. (RT)
