Students need to reflect on the practice of science to fully understand the nature of science (NOS), which is an important component of scientific literacy. In this paper, the authors describe how to implement an explicit and reflective pedagogy in college science laboratories and share examples from their implementation in a multiple-section…

Discusses an experiment which introduces students to the effects of electrical forces on the motion of macroscopic objects. Included are the proecedures of measuring the charge-to-mass ratio from deflections of charged water drops in horizontal fields and the overall charges delivered in a Faraday cup. (CC)

Discusses an experiment for the measurement of the half-life of cosmic ray muons by using a single scintillator detector. (LS)

The treatment group of first-graders received audio-tutorial instruction in the particulate nature of matter; the control group received audio-tutorial instruction in a nonscience subject. The treatment group used a particulate model to explain the nature of smells much more effectively than the control group. (MLH)

By using minimal equipment it is possible to demonstrate Faraday's Law. An electronic desk calculator enables sophomore students to solve a difficult mathematical expression for the induced EMF. Polaroid pictures of the plot of induced EMF, together with the computer facility, enables students to make comparisons. (PS)

Describes how the Joule-Thomson porous plug experiment may be used to illustrate the usefulness of the enthalpy function, irreversibility, steady-state ideas, and a relativity principle inherent in Newtonian mechanics. Bibliography. (LC)

Describes an introductory physics experiment concerned with scattering particles off various force centers. The experiment uses simulation techniques and a computer. The scattering is classical, and the student examines plots of computed particle trajectories. The results illustrate the concepts of differential corss-section, total cross-section,…

Describes an approach which begins with observations and systems familiar to the student and proceeds to develop and test models to explain them. Experimental topics include Brownian motion, a germinating cell, phase change of p-dichlorobenzene, extension and contraction of rubber, and an enzyme system. (GS)
