In hydrostatics, pressure measurement with U-gauges and their relationship to density is a well-known experiment. Very little is studied or experimented with the dynamics of the movement of a liquid in a U-tube probably due to its theoretical complexity but, after all, it is a simple damped oscillating system. In this paper we present a relatively…

This laboratory experiment utilizes an exploration of the storage stability of beer to introduce basic aspects of electron-paramagnetic-resonance (EPR) spectroscopy. Radicals formed upon aerobic forced-aging of beer samples are established by using a spin-trap. The students are introduced to basic principles of EPR spectroscopy and food and…

Propagation of sound waves is one of the fundamental concepts in physics. Some of the properties of sound propagation such as attenuation of sound intensity with increasing distance are familiar to everybody from the experiences of daily life. However, the frequency dependence of sound propagation and the effect of acoustics in confined…

The MicRoboCop project introduces chemistry students to the concepts and protocols of synthetic biology. MicRoboCop is a biosensor that has been designed for unique applications in forensic chemistry. The lab is carried out in collaboration with an instructor teaching a genetics course. Students in the biology course synthesize biosensors using…

Reported herein is the design, implementation, and evaluation of a full-day outreach program for high school girls that focuses entirely on sugar-related activities. The program, which we ran in February 2016 and February 2017, included multiple hands-on sugar-based experiments to increase the participants' interest in and enthusiasm for science.…

For a variety of reasons, understanding oxidation-reduction (redox) reactions can be challenging for introductory chemistry students. To provide an experiential foundation for students to learn redox concepts, we developed a laboratory experiment that frames redox reactions as a simulated murder mystery. In this experiment, permanganate, which…

Cosmic expansion is an important concept in astronomy. For ease of understanding, astronomers generally draw an analogy between cosmic expansion and the expansion of a spherical surface in 3D space. This study theoretically and experimentally investigates the laws governing the motion of particles on the surface of a balloon during expansion.…

We present a versatile experimental apparatus for exploring rotational motion through the interplay between the moment of inertia, torque, and rotational kinetic energy of a wheel. The heart of this experiment uses a 3D-printed wheel along with easily accessible stock components that allow for the adjustment of the moment of inertia while keeping…

This research aimed to reveal the opinions of the university students who conducted original educational videos context for the experiments in the Biochemistry laboratory course. Participants were fourth year students (N=40) of the Mathematics and Science Education Department, in Chemistry Education Program. A case study was used and carried out…

This article describes a new competence-oriented teaching rationale for a science course, developed in Germany through close cooperation between teachers and researchers, that seeks to improve scientific literacy at upper-level secondary school (ages 15-17). Its aim is to help students become independent and competent experimenters by combining…

This paper presents exemplification of the ways in which teachers can incorporate the ideology of maker education into STEAM club activities. The intention is to showcase how science teachers can infuse making into their pedagogy and inject more creativity into the learning process, yet still link it to existing science curricula, more…

Integrating authentic research-based experiences that mimic real-world scientific practices and relevance to student personal life into a chemistry curriculum can make abstract chemical principles more palpable to students. Unfortunately, many reported research-based experiences chemistry laboratory experiments lack relevance to a student's…

The purpose of this study was to develop a modern experimental apparatus using an Arduino with LabVIEW instead of the classical experiment. The wavelength of the sound was determined using the resonance of an air column. The smartphone app was used to generate the desired frequencies. A sound intensity and ultrasonic sensor was used to read the…

Much data, both published and anecdotal, have shown that students grasp scientific concepts more easily when they are directly involved in the learning via lab experiments or other hands-on activities. Hands-on or experiential learning also appears to aid in students' ability to retain scientific theory. One way to engage students in a first-year…

This study aims to examine the influence of inquiry-based instruction on eighth-grade male and female students' motivation and engagement in science learning in two public junior high schools in central Taiwan. Mixed-methods methodology was adopted with 60 students (32 males and 28 females) in the experimental group and 56 students (28 males and…
