This article seeks to provide researchers and practitioners in laboratory education, particularly those involved in the curriculum design and implementation of teaching laboratories at university level, with a conceptual framework and a working model for an integrated assessment of learning domains, by attending to a more holistic approach to…

Describes a physics laboratory experiment for nonscience majors intended to illustrate indirect experimental methods of sciences treating objects too small for sensory observation. The student explores and attempts to identify an object in a closed container, using provided experimental tools and small openings in the opaque lid. (MLH)

It is suggested that the work of Kammerer provides suitable material, in the form of case studies on which to base discussions of Lamarckism versus Darwinism. A set of structured problems is described as an example of possible problem-solving exercises, and further experiments to extend Kammerer's work are outlined. (Author/MA)

Describes a science laboratory experiment that can be done at home with the assistance of parents or older siblings. It is offered as an alternative to reading assignments or answering questions for homework. Parental assistance is encouraged. (SA)

Notes that laboratory work should be more oriented towards puzzle solving rather than technique or illustration. Offers three organic laboratory puzzles which can be solved by melting point alone. Involves lab work at the 100-200-mg scale but still uses conventional glassware. (MVL)

Describes a physical chemistry experiment which uses spectroscopy to measure the heat of formation of Na2SiF6. Discusses the opportunities for students to see the use of a familiar instrument in an unfamiliar application, emphasizing that there are often many ways to attack problems in science. (TW)

Demonstrates a laboratory to teach the concept of moment of inertia in which students are asked to identify four objects of equal mass sealed in unopenable containers by identifying the mass distribution of each object. Gives instructions to build an instrument to determine relative distribution of mass. (MDH)

Describes how Newton's Law of Cooling and the Method of Mixtures are used to solve the basic dilemma of whether to add the cool cream to the hot coffee or to let the black coffee cool down first and then add the cream. (ZWH)

Describes a computer program used in an experiment in which the partial molal volumes of sodium chloride solutions are calculated as a function of concentration from densities measured with a pycnometer. The complete program listing (also available from the author on disk) and a sample run are included. (JN)

Presents a six-step problem-solving process which the author has used to present creative science investigations to fourth, fifth, and sixth graders. (Author/SJL)

Explores strategies in the situation of a runner trying to evade a tackler on a football field. Enables the student to test intuitive strategies in a familiar situation using simple graphical and numerical methods or direct experimentation. (JRH)

Presents problems appropriate for high school and college students that highlight dilution methods. Promotes an understanding of dilution methods in order to prevent the unnecessary waste of chemicals and glassware in biology laboratories. (JRH)

Describes a physics experiment which demonstrates the pitfalls of assuming that a model which represents an ideal system is applicable to a real experiment. Explains how the failure may give greater understanding of the problem and may lead to improvements in the model. (ML)

Describes a project-type experiment in which students each try to find the color indicator present in a particular flower. The philosophy of conducting such an experiment and procedures used are included. (JN)

Presents experiments to introduce students to the phenomenon of biological rhythmicity and to reinforce the fact that there are differences in the physiology of human beings. (Author/MA)
