In a technology-enhanced learning environment and underpinned by a unique hybrid pedagogic model that borrows from gamification, constructivism, and experiential learning approaches, badges were purposefully used to foster engagement. This approach promoted the development of a mindset that identifies and appreciates the worth of a portfolio of…

Describes a blood coagulation test developed by two high school biology students. Although the test lacks some precision, results indicate that the technique is comparable to standard methods used in laboratories. (MA)

These supplemental units contain four laboratory exercises that can be used to enhance the labs in "Physics for the Technologies." The four units (one mechanical, two thermal, and one electrical) are designed to enhance labs in presenting specific concepts. Each unit can be used as an example of how the concepts behind the theory apply…

Describes an experiment to characterize the enzyme polyphenol oxidase. Includes Purpose, Reagents and Equipment, Procedure, Extraction, Treatment of Data, and Discussion. (MA)

This second report from the Analytical Chemistry Subcommittee presents ideas for using real-life samples for student analysis and for introducing the topic of developing procedures for analysis. (DT)

Describes a two-hour physics laboratory experiment modeling the phenomena of eclipsing binary stars developed by the Air Force Academy as part of a week-long laboratory-oriented experience for visiting high school students. (BT)

Reviews research related to laboratory work and makes recommendations for the classroom on how to make labs more meaningful. Argues that pre- and post-laboratory discussions containing theory behind the lab and purposes of the lab are essential for new understanding. (DDR)

An activity in which students combine physical and mathematical principles in a measurement situation is described. (SD)

Describes a method for experimenting with both whitening and deacidifying old newspaper clippings using sodium borohydride bleaching. Clippings are soaked in distilled water then immersed in sodium borohydride for 15-20 minutes. After rinsing with distilled water, the paper is washed with saturated Ca(OH)2 solution. Readers should not begin…

Describes a project designed to introduce infrared spectroscopy as a structure-determination technique. Students are introduced to infrared spectroscopy fundamentals then try to determine the identity of an unknown liquid from its infrared spectrum and molecular weight. The project demonstrates that only rarely can the identity of even simple…

Described are the morphology, eating habits, and habitats of three types of Bryozoan colonies. Information on where to collect these organisms and how they can be cultured are included. Suggestions are given for lab experiments that can be done with type three colonies and Euglena. (MA)

Describes a laboratory experiment for secondary school chemistry students utilizing the classic reaction between the iron(III) ion and the thiocyanate ion. The experiment also works very well in other chemistry courses as an experience in spectrophotometric analysis. (PVD)

Describes a basic introductory chemistry experiment for science majors which departs from synthesis and moves instead into the realm of formulation. As part of a project that reorganizes the introductory chemistry sequence according to subjects with which students are acquainted, this laboratory makes use of oxidation-reduction chemistry to make…

This resource guide provides information for 13 laboratory experiments designed to be conducted in small schools with limited equipment and materials. For each experiment, the document outlines necessary equipment and materials, experiment procedures, and questions to be answered. The experiments are: (1) studying the properties of water; (2)…

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,…
