We report on a distance learning experimental project for chemistry-major students on the synthesis of ethyl dodecanoate (C[subscript 11]CO[subscript 2]Et), a model for biodiesel, considering green chemistry principles. Thus, we employed a "recyclable acid catalyst" (an ionic liquid) and used chemometrics and microwave heating (MW) to…

Newton's cradle is a well-known physics toy that is commonly used by teachers to demonstrate conservation laws in mechanics. It can also be used to investigate the physics of colliding objects, by recording motion of the balls on video film. Various experiments are described using 3-ball and 5-ball cradles, showing how different types of collision…

The vertical bounce of a plastic egg was investigated by dropping the egg on a horizontal surface and filming the result with a video camera. If the egg is dropped on one end then it bounces just like a spherical ball. If the top end of the egg is pointing forwards or backwards when it lands on the surface, or if the egg is spinning when it lands,…

The infrared camera, or thermal imaging camera, can be used to complement the teaching of a number of topics in high school science. Here, we provide seven examples of its application in teaching physics, chemistry and biology concepts at high school level. We also discuss its strengths for such applications and provide some pointers for science…

A vacuum cleaner is used to isolate over twelve harmonics in a corrugated toy whistling tube. The toy tube is first taped along a horizontal surface. Then a vacuum cleaner with a hose diameter approximately the same as that for the toy tube is turned on. As the vacuum cleaner hose approaches one end of the corrugated tube, individual higher…

Lecture-only chemistry courses without a dedicated laboratory component present a significant challenge for instructors to reinforce course content with hands-on learning experiences. This is especially true for lecture courses in which students are unable to directly visualize and operate instrumentation. Herein, we present an in-class activity…

Your body is not a point particle. The nature and direction of the forces counteracting gravity influence your experience of uniform rectilinear motion--as does your own orientation in relation to the force of gravity. Sensors in smartphones or other devices can capture these forces, and help establish a connection between the personal experience…

The chemistry of metal-organic frameworks (MOFs), a new class of emerging crystalline porous solids with three-dimensional (3D) networks composed of metals and multidentate organic molecules, was introduced by using three differently shaped crystals. We reported new and mild MOF synthesis methods that are simple and devised to be performed in high…

This successful guide--now in a revised and expanded second edition--gives teachers effective strategies to support adolescents' development of relevant literacy skills in specific disciplines. Demonstrating why disciplinary literacies matter, the authors discuss ways to teach close reading of complex texts; discipline-specific argumentation,…

Physics students have traditionally prepared many kinds of reports-- laboratory, activity, project, and even book or article reports. Smartphones and YouTube videos are familiar cultural objects to current students, and our students use smartphone cameras to include photographs of apparatus, phenomena, hand-sketched figures, graphs, and…

Students in introductory physics courses encounter harmonics when they study standing waves on strings and in pipes. The Fourier spectrum, which plots amplitude against harmonic number, can describe all periodic tones imaginable. However, most sounds are aperiodic and therefore have additional spectral components. A real-world application that…

I am inspired to write this article after coming across some publications in "The Physics Teacher" that all hit on topics of personal interest and experience. Similarly to Christensen my goal in writing this is to encourage other physics educators to take advantage of modern technology in delivering content to students and to feel…

This guided-inquiry, upper-division undergraduate organic lab experiment, a hybrid of problem-based learning (PBL); process-oriented, guided-inquiry learning (POGIL); and peer-led team learning (PLTL) has been developed to ease the transition from the undergraduate lab to a research lab environment. The characterization of a mixture of camphor and…

In this article, we share design guidelines for the development and use of online, video-based "teaching playgrounds," which provide opportunities for prospective teachers to engage in professional noticing of teaching practices. Through teaching playgrounds, we provide an instantiation of the Presence+Experience framework, which…

This book has been prepared to introduce common technological tools that can be used in science education in the distance education process. Although most of the applications introduced in the book are used in face-to-face education, this book focuses on their use in the distance science education process. In the Introduction part of the book, the…
