Background: Achieving the targeted of university physics courses and improving student motivation requires varying types of instructional design. One alternative approach to the traditional lecture format involves the use of historical science stories, which are narratives that present episodes from the life of a scientist, as well as…

The Internet of Things (IoT) is a network of objects that can exchange data with other devices also connected to the Internet. One of the most common consumer examples of IoT is home automation, as a variety of smart devices, including doorbells, lightbulbs, thermostats, and refrigerators are now available which users can control remotely using…

At the beginning of 2020, the COVID-19 pandemic surprised the world, affecting activities that promote attendance, including abruptly impacting the education area. Educational institutions, from preschool to university, were required to adopt alternative teaching methods to continue their activities. Distance learning has been adopted by educators…

The reform documents point out the necessity of teaching the plurality of scientific method (SM) when scientists engage in scientific practices (SPs). The dramatic change in education due to COVID-19 pandemic necessitates examining the outcomes of online education, especially laboratory applications courses, which the students and educators used…

Electrophoresis is integral to analytical and biochemistry experiences in undergraduate education; however, fundamental principles of the method are often taught in upper-level laboratories through hands-on experiences. A laboratory activity is reported that teaches the concepts of electrophoretic mobility and electroosmotic flow. A single…

A lot of new science has been inspired by common phenomena and even by old traditions practiced in our daily lives. Eventually, after deep exploration, this may engender unexpected new technologies. In this paper, inspired by the wearing of a traditional cloth called a "sarong," by the community in South East Asian countries and others,…

So many fundamental physics problems involve rigid body rotation that mastery of the subject is essential to many science and engineering undergraduate degrees. Rigid body rotation is typically taught in introductory mechanics courses and while students are generally comfortable with the corresponding kinematic equations, torques and moments of…

Virtual laboratory simulations can contribute to the educational objectives related to practical classes, especially in situations of online or hybrid teaching. We present a proposal for laboratory activity involving the quantification of proteins with the biuret reaction and measurement by visible light spectrometry. The student will be able to…

A glass of water covered with a disk with a hole in it can be turned upside down without spilling the water in the glass, provided the hole is small enough and the disk is pressed against the rim of the glass. A quasistatic numerical simulation based on hydrostatic pressure and surface tension of water was used calculate the critical hole diameter…

Blood flow through the cardiovascular system is governed by the same physical rules that govern the flow of water through domestic plumbing. Using this analogy in a teaching laboratory, a model of the cardiovascular system constructed of pumps and pipes was used to demonstrate the basic interactions of pressure, flow, and resistance in a regulated…

Interactive computer simulations and hands-on experiments are important teaching methods in modern science education. Especially for the communication of complex current topics with social relevance (socioscientific issues), suitable methods in science education are of great importance. However, previous studies could not sufficiently clarify the…

Herein, we describe an accessible and safe organic chemistry lab experiment that can be completed at home. Liquid-liquid extraction is a fundamental organic chemistry lab experiment that touches on topics such as chemical structure, density, solubility, and acid-base chemistry. Given the increased demand for safe organic chemistry experiments that…

An important objective of any analytical chemistry course is for students to generate and interpret data from the analysis of complex, real-world samples in order to assess the effectiveness of the analysis method, including the calibration. In this laboratory exercise, students directly compare calibration methods (external standards and standard…

We have revamped a classic analytical chemistry laboratory experiment, "Determination of an Unknown Acid", to provide students an opportunity to learn about new advances in the material sciences and their applications in analytical chemistry in an effort to reinforce the key concepts of chemical analysis. Specifically, students were…

This article introduces a novel experiment that involves vitrimers, a new type of polymer, in polymer chemistry and physics lab courses for undergraduate students. Vitrimers are permanently cross-linked networks that can be reprocessed under certain external stimuli. Therefore, they combine the advantages of traditional thermoplastics (excellent…
