The five papers published by Hodgkin and Huxley in 1952 are seminal works in the field of physiology, earning their authors the Nobel Prize in 1963 and ushering in the era of membrane biophysics. The papers present a considerable challenge to the novice student, but this has been partly allayed by recent publications that have updated the…

This article reports on a new device, called a geyser guide, that allows for quantitative measurements of both bubble sizes and kinetics of foam production in the so-called Diet Coke and Mentos experiment. The device is easily constructed, is made using readily available materials, and allows the experiment to be carried out indoors with no mess.…

The need to develop interest in STEM (science, technology, engineering, and mathematics) skills in young pupils has driven many educational systems to include STEM as a subject in primary schools. In this work, a science kit aimed at children from 8 to 14 years old is presented as a support platform for an innovative and stimulating approach to…

An introductory guide to deducing the mechanism of chemical reactions is presented. Following a typical workflow for probing reaction mechanism, the guide introduces a wide range of kinetic and mechanistic tools. In addition to serving as a broad introduction to mechanistic analysis for students and researchers, the guide has also been used by…

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.…

The Case Study Compilation was developed with and for educators to provide examples of practice related to three questions: (1) What does it mean to focus on social-emotional development and the creation of positive learning environments?; (2) How can educators integrate their approaches to social, emotional, and academic development?; and (3)…

In his introduction to the science shows feature in "Primary Science" 115, Ian B. Dunne asks the question "Why have science shows?" He lists a host of very sound reasons, starting with because "science is fun" so why not engage and entertain, inspire, grab attention and encourage them to learn? He goes onto to state that: "Even in today's…

College students in the non-English-speaking world have to overcome formidable barriers in reading and writing when their medium of instruction is English. One particular problem faced by science majors is the writing of lab reports, a demanding task that might not be effectively supported by the standard guides and manuals available. This paper…

Research is a process by which people discover or create new knowledge about the world in which they live. The International Science and Engineering Fair (ISEF) and Affiliated Fairs are research (data) driven. Students design research projects that provide quantitative data through experimentation followed by analysis and application of that data.…

The study was an experimental comparison of the structured versus unstructed training of semiskilled production workers. The experiment was implemented using the following procedures, which are presented in detail: a representative semiskilled production job was selected, the two training programs were characterized and developed, trainees…
