Presented is a project-based learning (PBL) laboratory approach for an upper-division environmental chemistry or quantitative analysis course. In this work, a combined laboratory class of 11 environmental chemistry students developed a method based on published EPA methods for the extraction of dichlorodiphenyltrichloroethane (DDT) and its…

In the field of Virtual Reality (VR) and Augmented Reality (AR), technologies have made huge progress during the last years and also reached the field of education. The virtuality continuum, ranging from pure virtuality on one side to the real world on the other, has been successfully covered by the use of immersive technologies like head-mounted…

The resonance phenomenon is widely known in physics courses. Qualitatively speaking, resonance takes place in a driven oscillating system whenever the frequency approaches the natural frequency, resulting in maximal oscillatory amplitude. Very closely related to resonance is the phenomenon of mechanical beating, which occurs when the driving and…

Satellite laboratories, designed to ignite interest in technical and computer science topics, employ cross-age peer tutoring and physical computing platforms. Catering to students from 5th grade onwards, these laboratories are led by tutors from 9th grade onwards. Employing a design-based research approach, the project aims to comprehensively…

This study investigated (i) the effect of inquiry-oriented laboratory activities on preservice primary school teachers' (PPSTs) achievement in science process skills (SPS) and science teaching efficacy beliefs, and (ii) changes in groups' reflections of SPS in the laboratory reports as they engaged in the activities. There were 71 PPSTs enrolled…

In U.S. school systems, anti-Blackness and ableism are organizing principles that constitute a system of exclusion through which to dismiss complex intersectional identities of Black, Indigenous, and People of Color (BIPOC) students with and without disabilities. Racialized outcome disparities in the identification of disability and school…

Various experiments and demonstrations relate air pressure and air pressure difference to force and area. Carpenter and Minnix describe a large-scale pneumatic lift in which a person sitting on a board atop a plastic garbage bag is lifted when the bag is connected to the exhaustport of a vacuum cleaner, which easily lifts the person. This article…

We discuss the successful creation and implementation of a biotechnology track within the chemical engineering unit operations course. The track focuses on engineering principles relevant to brewing. Following laboratory modules investigating heat transfer processes and yeast fermentation kinetics, student groups design and implement a project to…

Iron metabolism is an important subject of study for undergraduate students of chemistry and biochemistry. Relevant laboratory exercises are scarce in the literature but would be very helpful in assisting students grasp key concepts. The experiment described here deals with different iron release mechanisms of two protagonists in iron metabolism:…

In this article, the authors reflect on Myrna's Children's Village, their university laboratory school located in southern New Mexico in the USA. The Village serves children from the age of six weeks to five years through an array of early childhood programs. This diversity provides a unique context, while also posing issues and concerns, such as…

The Advancing Science and Engineering through Laboratory Learning (ASELL) for Schools program has been instrumental in getting schools across Australia to reconsider the effectiveness of the laboratory learning activity (LLA) in science education. In Victoria, the ASELL for Schools project has collaborated with another nationally funded program,…

Historically, students from racially minoritized communities receive exclusionary disciplinary actions more frequently and severely in the United States. Researchers have recommended that schoolwide behavioral interventions implemented to address racial disproportionality need to be culturally responsive to local school contexts. Using the theory…

Reported herein is a multidisciplinary experiment for senior-level undergraduate teaching laboratories in the synthesis of the analytes acetaminophen and phenacetin; the fabrication of paper-based devices, using eyeliner, acrylic spray paint, or wax-printing, for sensing of those analytes; and the use of the newly fabricated devices for successful…

Most didactic lab experiments deal with the influence of temperature, concentration, pressure, surface area, and catalysts on chemical kinetics; however, few of them explore the influence of light radiation and the presence of inhibitor agents on reaction rates. In order to investigate the effects of the radiation source and the presence of…

A versatile experiment is described for the high school and college laboratory setting based on the synthesis of biobased polymers prepared from inexpensive, renewable, and nonhazardous chemicals. Combinations of readily available citric acid, glycerol, and tapioca root starch are used to prepare three polymeric materials with different observable…
