Enumerates five reasons for using science fiction as an aid in teaching science. Also included is a source list of materials that can be utilized. (BR)

Explains a projectile motion experiment involving a bow and arrow. Procedures to measure "muzzle" velocity, bow elastic potential energy, range, flight time, wind resistance, and masses are considered. (DH)

Describes the properties of colloids, listing those commonly encountered (such as whipped cream, mayonnaise, and fog). Also presents several experiments using colloids and discusses "Silly Putty," a colloid with viscoelastic properties whose counterintuitive properties result from its mixture of polymers. (DH)

Recommends using dramatic demonstrations on the energy in chemical systems as an audiovisual adjunct to lectures and laboratory sessions. Lists materials needed and provides procedures including safety tips for various experiments to produce chemical light, heat, and electricity; and concludes with hints for preparation/rehearsal. (JM)

Presents two models and two demonstrations targeted at student understanding of projectile motion as the sum of two independent, perpendicular vectors. Describes materials required, construction, and procedures used. Includes a discussion of teaching points appropriate to each demonstration or model. (JM)

Describes activities (demonstrations/experiments) used to introduce history of periodic properties--without electrons, orbitals, filling shells, or any conception of atoms beyond Dalton's model. Activities supplement first chapter in a currently available chemistry text. Indicates potential danger of experiments if proper safety precautions are…

Describes a student science exposition which includes individual research and team competitions, noncompetitive student exhibits, films, tours, workshops, and social events. Indicates that this combination of activities makes the exposition a real science "fair." (JN)

Discusses the rationale for using photochemistry to merge descriptive chemistry and molecular orbital theory in first-year chemistry courses. Includes procedures and safety information for various activities, demonstrations, and experiments involving photochemical reactions. (DH)

Describes an experiment involving the preparation of copper iodide that gives stoichiometric results. Materials needed and procedures are discussed along with ideas on different ways to analyze the data. Pertinent chemical equations are presented. (BC)

Instructions for constructing cross staffs and quadrants are provided. Astronomy teaching methods using the two devices are discussed. These include locating common constellations with the cross staff and following a star (or moon, sun, or planets) by reading the altitude and azimuth with the quadrant. (JN)
