Describes science activities which have been successful with nonscience majors. Each activity requires students to make observations, record the data gathered, interpret data, and prepare a written report. Subject areas include motion of stars, sunspots, lunar orbits, sunset points, meteor showers, and sun shadows. (JN)

Describes a classroom exercise that uses a letter from Max Delbruck to George Beadle to stimulate interest in the mechanics of a nonoverlapping comma-free code. Enables students to participate in the rich history of molecular biology and illustrates to them that scientists and science can be fun. (JRH)

Presents the results of a survey on evolution given to 392 university students in western Pennsylvania. Concludes that, although nearly three-quarters of the students say they believe in the theory of evolution, most do not understand the mechanism behind it. (PR)

Describes a simple conductivity apparatus for the determination of ionization and solubility product constants of various substances. The uses of the apparatus in determining the ionization constant of a weak monoprotic acid and in measuring the rate of diffusion of ions through a membrane are also presented. (HM)

Describes an activity which introduces students to the nature and challenges of paleoanthropology. In the exercise, students identify diagrammed bones and make interpretations about the creature. Presents questions and tasks employed in the lesson. (ML)

Describes a series of literature problems integrated into organic and biochemistry courses which direct students to seek specific information from specific sources. (GS)

Describes an introductory course in geology for nonscience majors that involves students in laboratory exercises related to rock classification. (GS)

Instructional strategies used in teaching oceanographic data collection techniques are discussed. These include having students examine actual data, plan and organize a research cruise on a specific budget, and analyze incomplete data sets. Rationale for using these strategies is included. (JN)

Techniques have been described for using celestial spheres as data-generating devices. Descibes a variation, capitalizing on students' interest in activities related to Stonehenge. Following a movie, students determine whether or not astronomical alignments found at Stonehenge and related structures could arise by chance. Local buildings are used.…

Describes the use of a weekly blackboard session as a way to improve instruction in an organic chemistry lecture. The instructor writes problems on the board and either alone or in groups, students write the answers on the board. Later, they explain their solutions to the class. (PR)

Describes types of meteors and micrometeorites that enter the Earth's atmosphere. Presents an activity where students collect micrometeorites with a strip of tape in an undisturbed outdoor area. After 24 hours, they examine the tape by sandwiching it between 2 glass slides and view through a microscope at 100X. (PR)

Describes the use and benefits of prosection--a dissection performed in advance and used by "nondissecting" students for detailed observation and study--in undergraduate laboratories. (PR)

Presents a science problem, involving the inhalation of hydrogen cyanide, that is used as an extra credit acitvity for chemistry students. (GS)

Presents a detailed discussion of the "Drinking Duck" toy and its use to illustrate scientific and technical issues in thermodynamics. Numerous illustrations and equations are included. (MA)
