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 lab to analyze plant and animal materials for the presence of carbohydrates, lipids, and proteins by describing and presenting simple tests in common breakfast food items. (MKR)

Teachers often use demonstrations to prepare students for a science experiment. This article describes a demonstration method to ensure that students are not supplied with all the answers before the actual experiment and to help them to remain an active part of the science lesson. (ZWH)

Provides basic information on the anatomy, physiology, behaviors, and distribution patterns of the box turtle. Offers suggestions for the turtle's care and maintenance in a classroom environment. (ML)

Presents experiments for isolating and detecting siderophores produced by bacteria or fungi. (MKR)

Presents a simple experiment that enables students to get a quantitative measure of the relationship between the resistance of a wire and the temperature of the wire allowing the calculation of the temperature coefficient of resistance. (JRH)

Describes the easy collection procedures and classroom uses of live planarians. Suggests that the use of live animals in the classroom will allow students to observe different biological processes exhibited by living organisms. (ZWH)

Describes the physics of an experiment in which an air wedge is formed between two glass plates inclined at a small angle by means of a thin spacer. Implications for instruction are noted. (JN)

This book presents science activities developed by teachers for children ages 3-6 years old. The activities aim to develop science skills including communication, observation, estimation, measurement, cause and effect, investigation, and evaluation in children by using their curiosity as a staring point. Activities include age suggestions, address…

Presents an experiment that demonstrates conservation of momentum and energy using a box on the ground moving backwards as it is struck by a projectile. Discusses lab calculations, setup, management, errors, and improvements. (JRH)

Presents an experiment to study the acceleration of a cart moving up and down an inclined plane. Demonstrates how multitiming and the study of the movement in both directions allows the determination of the component of gravitational force along an inclined plane without any assumptions about friction. (JRH)

Describes how microscale labs can be used as a tool to transform teaching instead of simply a less expensive substitute to traditional labs. Presents an activity that introduces students to density and the advantages of multiple measurements and averaging. (ZWH)

Provides an overview of obsidian hydration dating for the instructor by presenting: (1) principles of the method; (2) procedures; (3) applications; and (4) limitations. The theory of the method and one or more laboratory exercises can be easily introduced into the undergraduate geology curriculum. (JN)
