This paper was inspired by the numerous requests from "TPT" readers to expand the number of examples of "recurrent study" lab exercises described in my previous paper "Physics Labs with Flavor." I recommend that readers examine it first in order to better understand this one as my attempt here is to be brief. In that paper, one can find details…

For distance-education students, the requirement for a laboratory course can present a significant hurdle to completing degree requirements. To better serve these nontraditional students, the authors developed a distance version of the laboratory course to provide a hands-on experience similar to that of on-campus students. In order to make the…

This laboratory training manual on laser communications and fiber optics may be used in a general technology-communications course for ninth graders. Upon completion of this exercise, students achieve the following goals: match concepts with laser communication system parts; explain advantages of fiber optic cable over conventional copper wire;…

This laboratory manual on microbiology begins with an introduction relating the study of microorganisms to health occupations education and stressing the importance of teaching critical thinking. The introduction is followed by general instructions for the use of the manual and an illustration of hand washing procedures. The 13 laboratory…

We have designed a skills matrix to be used for developing and assessing undergraduate biochemistry and molecular biology laboratory curricula. We prepared the skills matrix for the Project Kaleidoscope Summer Institute workshop in Snowbird, Utah (July 2001) to help current and developing undergraduate biochemistry and molecular biology program…

This sourcebook contains a collection of laboratory exercises assembled for use in introductory physical geography classes taught at community colleges. Introductory sections address the origins of the sourcebook, the ways it differs from traditional laboratory manuals, and its form and anticipated use. Next, a list of terms or concepts,…

Hypothesizes that overloading the working memory may leave no space for thought and organization such that faulty (or even no) learning takes place. Provides examples of this hypothesis and possible remedies. These remedies focus on design of laboratory manuals and equipment and on curriculum content order. (JN)

Reported are observational limits of detectability for several single stimulus and multi-stimuli observation tasks in secondary level chemistry. Provided are tables of actual results obtained including type of observation, chemical system used, method of determining stimulus magnitude, and observational thresholds. (Author/YP)

Discusses the selection of gloves for the chemistry laboratory. Provides checklists for the purposes of the gloves, and the factors including permeation rate, breakthrough time, friction, and cost. Lists eight rules for preventing skin exposure and minimizing area contamination. Lists six references. (YP)

Automatic Picture Transmission (APT) images are real-time weather pictures transmitted from satellites on a radio frequency in a video format. Amateur radio enthusiasts and electronic experimenters have for a number of years designed, built, and operated direct readout stations capable of receiving APT photographs. The equipment to receive weather…

This lab manual is designed to accompany a college course introducing students to computing. The exercises are designed to be completed by the average student in a supervised 2-hour block of time at a computer lab over 15 weeks. The intent of each lab session is to introduce a topic and have the student feel comfortable with the use of the machine…

This document provides teachers with sources of useful information and new ideas about the high school chemistry laboratory program. Chapters included are: (1) "Introduction" describing the philosophy and specific objectives of this project; (2) "Importance of Laboratory Work"; (3) "Chemistry Lab Outline" listing…

This guide contains 43 modules of laboratory activities for technology education courses. Each module includes an instructor's resource sheet and the student laboratory activity. Instructor's resource sheets include some or all of the following elements: module number, course title, activity topic, estimated time, essential elements, objectives,…

Offers challenging work at a higher level of technique than most students meet in elementary laboratory work. Uses a combined weight and volumetric sequence not shown in textbooks. Notes modern rapid balances help lower evaporation loss during weighings. Discusses the balance, weights, and buoyancy considerations. (MVL)

Notes that this experiment takes safety and noncarcinogenic reactants into account. Demonstrates the use of diazonium salts for the replacement of an aromatic amine group by a phenolic hydroxyl. Involves two pleasant-smelling organic compounds, methyl anthranilate (grape) and methyl salicylate (oil of wintergreen). (MVL)
