Students in a typical instrumental analysis course may learn more than 30 analytical techniques. There are more than 150 components associated with the instrumentation that they learn. To help students organize this large amount of information, we classified these components into four categories: sources, samples, discriminators, and detectors. In…

Nowadays, inquiry-based learning is getting a lot of attention as an effective education method. Therefore, it has been researched and implemented in various countries. Inquiry-based learning has been used in various subjects such as biology, mathematics, social studies, and others. In order to encourage a smooth implementation of inquiry-based…

Among the many decisions to be made in their teaching practice, physics teachers must decide how to explain each particular phenomenon to students. This study explores student teachers' ("STs") decision-making process when presented with several explanations of a physical phenomenon that might be used for teaching purposes. During…

The objectives of the present study are to investigate both the history of the collection of scientific instruments from the Maraslean Teaching Center (MTC) and the potential for the collection's use in STEM education programs. Although MTC went by a number of different names during its long history, its institutional goal remained the same:…

Today's students are increasingly immersed in a landscape of screens and handheld digital devices through which a good deal of their interactions with the world around them are mediated. Physics educators, meanwhile, continue to rely on traditional human interactions with the physical world, such as sliding down a ramp or throwing a baseball, in…

In this paper I present various equatorial sundial designs that use diffraction on a CD to display time. The designs described in the paper include a transparent CD sundial equipped with a small terrestrial globe. This sundial is compact, pedagogically useful, can be used throughout the year, and provides the user with a wealth of information.

An interdisciplinary approach to science education through history of art is proposed. The approach is innovative, as the artworks complement the history, philosophy and sociology of science contents to increase students' interest and motivation. The approach integrates humanities and science education through history of art, which requests…

The study of buoyancy becomes very interesting when we measure the apparent weight of the body and the liquid vessel weight. In this paper, we propose an experimental apparatus that measures both the forces mentioned before as a function of the depth that a cylinder is sunk into the water. It is done using two load cells connected to an Arduino.…

Mass spectrometry is one of the few instrumental analysis techniques that can be relatively well-understood with physics/chemistry knowledge typical of an advanced high school or a beginning undergraduate student. This positions mass spectrometry well to be used as a bridge between abstract concepts typically set as learning goals in courses at…

This work focuses on the experimental demonstration of the hydrostatic paradox using simple tools in the form of plastic bottles and plastic syringes with a thread. For the evaluation of the results obtained the data logger Lab Quest Vernier was used. The construction of the device is presented in the first part of this paper. The second part…

Recently, with the influence of science, technology, engineering, and mathematics education approach, the material design has become an important aspect within science courses. The material development course in science curriculums is a unique opportunity to evaluate pre-service teachers' material designs. In this study, student science teachers'…

This article describes an experiment teaching polarization phenomena and the Triboelectric Series in a unit on electrostatics. Using rods (2-3 ft in length) made from wood, aluminum, PVC, and Plexiglas on an inverted watch glass, these items demonstrated to the class how a party balloon rubbed with fake rabbit fur (charging the balloon negative)…

I report an innovation that provides a compelling demonstration of rocket propulsion, appropriate for students of physics and other physical sciences. An electrical spark is initiated from a distance to cause the deflagration of a combustible vapor mixed with air in a lightweight plastic bottle that is consequently propelled as a rocket by the…

Portuguese schools hold important collections, most organised in the late nineteenth and early twentieth centuries. This scientific heritage, however, is still to be discovered. This article focuses on the creation, development, and role of natural history collections in Portuguese secondary schools, between the second half of the nineteenth…

This paper reports a simple magnetically driven oscillator, designed and resolved in order to achieve a better student understanding and to overcome certain instructional difficulties. The apparatus is mainly comprised of an ordinary spring pendulum with a neodymium magnet attached to the bottom, a coil placed in the same vertical direction, an…
