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…

Teachers are provided with several experiments for primary students that address concepts related to the properties of air, sound, and water. (IAH)

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)

Describes experiments designed to investigate the cooling rate of microwave-boiled water as compared to that of stove-boiled water. Concludes that within experimental limits, microwave-boiled water and stove-boiled water cool at the same rate. (JRH)

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)

You can't see, smell or taste air - but here's an easy method for experimenting with it. (Editor)

Points out the benefits of "sciencing"--helping children learn the methodology and processes of scientific investigation through the use of play experimentation. (SKC)

The use of a logarithmic amplifier preceding an oscilloscope's vertical amplifier is described for physics teachers who want to demonstrate the exponential decay nature of some phenomena. (Author/SA)

Intended for the elementary teacher who lacks science teaching experience, this article presents tips for finding background information and for stocking a portable "science lab" with everyday materials. It also outlines 10 easy experiments. (SJL)

An activity is described that is designed to give students a chance to learn about speed by calculating their own running or walking speed and the speed of cars. (MP)

Describes an experiment that uses the ultrasonic transducer for demonstrating the Fourier components of waveshapes such as the square and triangular waves produced by laboratory function generators. (JRH)

Discusses the rationale for and use of minilabs (requiring from 15 to 90 minutes to complete) for freshmen chemistry experiments. Provides several examples, advantages for students and instructors, and results of a questionnaire evaluation completed by 83 students. (JN)

This article offers ideas and activities to help develop a multidisciplinary unit that motivates students to learn about the languages, legends, and lifestyles of Native Americans. (DF)

Describes an introductory laboratory format (used for 12 years at Colorado College) that involves students in the design and exploration phases of experiments. The laboratory features include choices of experiments; clearly explained goals; student selection of methods; wise equipment use; check-out procedures with instructor questions; and no…

Presents demonstrations, using microprocessors, to show the slow change in relative phase of two sine waves feeding the inputs of an oscilloscope and Fourier synthesis. (SK)
