Laboratory classes effectively enhance student understanding and appreciation of course concepts. With course delivery suddenly shifted into the online format due to the COVID-19 pandemic, four laboratory exercises in each of two introductory-level soil science courses were converted into virtual sessions delivered in the form of…

A guide for instructors and laboratory assistants to prepare some common aqueous reagents used in an undergraduate laboratory is presented. Dilute reagents consisting of H[superscript +](aq), I[subscript 3][superscript-](aq), Ce[superscript 4+](aq), and Ag[superscript+](aq) were prepared by electrolytic oxidation of respective precursors.…

This report reviews some goals for laboratory activities in contemporary science teaching, discusses an investigation that analyzed and compared laboratory activities from two major physics guides, and discusses the implications of the goals and analysis for physics teaching. Six major deficiencies in the two laboratory handbooks are identified.…

Discusses some problem areas as they presently exist in many secondary school laboratories in Australia, and presents some views on how safety in science should be presented to the Australian students. (Author/HM)

A MANUAL WAS PRODUCED CONTAINING LABORATORY PROCEDURES FOR A ONE-SEMESTER COURSE IN ELEMENTARY QUANTITATIVE CHEMISTRY ON A COLLEGE FRESHMAN LEVEL. MATERIALS AND TOPICS WERE EXAMINED AND CHOSEN AS TO DESIRABILITY, PRACTICALITY, AND EDUCATIONAL VALUE. OPTIONAL EXPERIMENTS WERE ALSO INCLUDED. THE LABORATORY PROCEDURES WERE TESTED ON SOPHOMORES AND ON…

This handbook is based on a list of essential topics that should be mastered by the student who subsequently plans to pursue college chemistry. Chapters include: (1) "Introduction" (describing a position paper and the background of the handbook); (2) "Essential General Topics and Objectives"; (3) "Testing Students"…
