Understanding the physicochemical properties of organic compounds with potential biological uses is central in current research topics. Thus, students must pursue the integration of different fields of chemistry to obtain and understand the physicochemical parameters that characterize the mechanism of action of key organics compounds. This…

Astronomy is one of the few sciences where the data (star-light) can be seen by all. Yet, there is a disconnect between a typical undergraduate lecture and, for example, where a planet may be in the sky and how to observe it. With the advent of moderate cost, high-quality 'back-garden' astronomy, and standard computers powerful enough to produce…

In this article we present a simple experimental set-up to determine the band gap of germanium and silicon using the "ExpEYES-17" kit. The experiment is based on the temperature dependence of the reverse current through germanium and silicon diodes at different temperatures. The experimental values are found to agree well with accepted…

Interest in virtual laboratory simulations as a pedagogical tool continues to grow, given the advantages of flexibility, scalability, technology integration, and interactive visualizations. We developed a laboratory model that integrates virtual lab simulations (VLS) and traditional in-person (IP) lab experiences for targeted skill development. In…

The use of two-dimensional images to teach students about three-dimensional molecules continues to be a prevalent issue in many classrooms. As affordable visualization technologies continue to advance, there has been an increasing interest to utilize novel technology, such as augmented reality (AR), in the development of molecular visualization…

Incorporation of previously reported AR technology (ARiEL) for a general chemistry laboratory was attempted for the second time, a replication effort designed to provide students with an option to read about the nature of instruments used in an experiment. Students' app usage was tracked to understand the type and amount of information accessed,…

The importance of introducing computational approaches early and actively in science education is widely acknowledged among educators and scientists. Many great ideas have been put forward and implemented by advocates and organizations such as Partnership for Integration of Computation into Undergraduate Physics (https://www.compadre.org/PICUP)…

We present a computer-based experiment that simulates the accretion process and generates fluffy aggregates with fractal nature. The Box Counting is performed without the aid of an image processing tool by using the coordinate information of the constituents of the aggregate. A simple algorithm to create aggregate and calculate box-dimension will…

We present a modernization of the undergraduate physical chemistry laboratory experiment for determining the speed of sound in various gases from resonant frequencies in a spherical resonator. The resonator (schematic IR = 7.5 cm) is constructed by 3D printing with eco-friendly poly(lactic acid), a commercially viable alternative to traditional…

The video of a free-falling object was analysed in Tracker in order to extract the position and time data. On the basis of these data, the velocity, gravitational potential energy, kinetic energy, and the work done by gravity were obtained. These led to a rather simultaneous validation of the conservation law of energy and the work-energy theorem.…

This article describes the use and advantages of the MATLAB-based program ReshmoBeam, developed to perform beam analysis, as it is done in statics courses of engineering curricula. An important goal of the article is to facilitate the dissemination of the program among faculty teaching these courses. The program is offered free to interested…

Course-based undergraduate research experiences (CUREs) allow students to apply the scientific method to novel questions, which can serve as a gateway for mentored research. Here, we present a model for using cross-disciplinary CUREs to vertically integrate courses from different disciplines. This approach creates opportunities for students to (1)…

Nowadays, novel Biochemistry lab techniques are being introduced at a very fast pace in scientific research. This requires development of new labs for undergraduate Biochemistry courses to equip the students with up-to-date techniques. However, the time limit of Biochemistry labs for undergraduate students represents a major obstacle. This article…

Mass transfer separations are of extreme importance to professionals working in the chemical industry. For this reason, chemical engineering and industrial chemistry students are both taught these unit operations at the final years of their study programs. The traditional way of carrying out their design is based on the use of deterministic…

A laboratory experiment characterized by a whole-class data-pooling approach to generate a data set that can be used to test a model of the influence of ionic strength on electrolyte solubility is described and discussed. The design of the experiment makes efficient use of the laboratory period and releases time for instructional and dialogic…
