Consistency and self-esteem theories make contrasting predictions about the relationship between a person's self-evaluation and his liking for an evaluator. Laboratory experiments confirmed predictions about these theories. (Editor/RK)

Describes nine biology experiments, including osmosis, genetics; oxygen content of blood, enzymes in bean seedlings, preparation of bird skins, vascularization in bean seedlings, a game called "sequences" (applied to review situations), crossword puzzle for human respiration, and physiology of the woodlouse. (CS)

Describes a computerized experiment in which the student determines the pk of an acid-base indicator from absorption spectra of the indicator at various concentrations. (MLH)

Contains information regarding pollen and human allergies. Lists most common types of pollen, describes pollen morphology, diagrams and apparatus for collecting pollen, and suggests laboratory activities such as pollen counts, pollen concentration, dispersal, and meteorological effects. (CS)

Presents two hydroboration-alkylation sequences, each requiring a three-hour laboratory period, that demonstrate the synthetic utility of the organoboranes. (MLH)

Describes a biochemistry experiment that illustrates the methodology of affinity chromatography by attaching avidin, a glycoprotein in egg white, to a Sepharose matrix in order to bind biotin-containing proteins. (MLH)

Describes the quantitative analysis of a gaseous mixture using peak heights and ratios between the peak heights. (MLH)

Describes the design, construction, and performance of a low-cost, transversely excited molecular nitrogen laser. Suggests simple experiments and demonstrations using this laser. (MLH)

A discrepant event is a happening contrary to our current beliefs. Discrepant events are said to be useful in clarifying concepts. This is one of the interesting features of current theories of constructivism. The story of Mpemba's ice cream is quite well known, but it is the educational aspects of the experiment that are of interest in this…

This paper presents the design and some results of a series of teaching experiments. The design was created to develop a model for everyday math lessons, that describes the conditions which foster or hinder the construction of new mathematical meanings. The development process includes the students' epistemic processes, their social interactions,…

This book contains the teacher's guide of the Environmental Inquiry curriculum series developed at Cornell University. It is designed to teach learning skills for investigating the behaviors of non-native and native species and demonstrate how to apply scientific knowledge to solve real-life problems. This book focuses on strange intruders…

The consolidation of the theoretical concepts as well as the use and learning of experimental techniques that are compatible with the technological evolution has been the main goals in Thermodynamics and Heat Transfer and Thermal Systems Laboratories at Escola Politecnica of University of Sao Paulo. The infra-structure and experimental benches in…

This teaching guide introduces a relativity gyroscope experiment aiming to test two unverified predictions of Albert Einstein's general theory of relativity. An introduction to the theory includes the following sections: (1) "Spacetime, Curved Spacetime, and Frame-Dragging"; (2) "'Seeing' Spacetime with Gyroscopes"; (3)…

How does a tiny seed sprout and grow into a towering tree? Join the kids from M.A.P.L.E as they learn about some of the incredible transformations that a plant goes through during its lifetime. In All About Plant Structure & Growth, uncover the secrets of roots, stems and leaves - structures that are vital to a plant's role as an energy…

This paper proposes an Internet facility that will authentically provide laboratory experiments remotely. Such a facility is brought to the doors of the distance learner to help provide learning that is comparable to that offered for conventional students. The paper describes the development of a prototype remote laboratory system, including…
