In the context of introductory courses in physical geography and meteorology, it is common around February 2 for curiosity to arise among students regarding the veracity of "Groundhog Day" predictions. Historically, most instructors' immediate response to such inquiries has been a definitive "NO," emphasizing the impossibility…

Owing to factors such as poor water solubility of luminol and the instability and easy decomposition of hydrogen peroxide (H[subscript 2]O[subscript 2]), the accuracy and sensitivity of the detection of H[subscript 2]O[subscript 2] through the luminol electrochemiluminescence (ECL) system are limited. Herein, we propose a water-soluble…

Spectroscopy is an integral part of chemical research, and the operation of any spectroscopic instrument is critical in chemical education. This study presents a low-cost, do-it-yourself (DIY) style spectrophotometer system that can be adapted for UV--vis spectrophotometry, fluorimetry, and atomic emission spectroscopy applications. The DIY system…

Biotechnology students entering the workforce often struggle in their application of textbook knowledge to build the solutions that we see in science and health fields today. Some students may be naive to what a job in the biotechnology industry can encompass. Students should graduate having a firm grasp of the prospects of their field and have…

Some researchers have theorized that emotions while reading science texts influence learning in a wholistic way, such that overall positive or negative affect leads to different learning outcomes. Other researchers have envisioned that emotions fluctuate during reading such that the degree of cycling impacts the learning outcomes. In this study,…

This study aims to prepare a scale to determine the creativity levels of prospective teachers studying at the undergraduate level of science teaching. In this context, 15 questions, suitable for student's level from physics, chemistry, biology, astronomy and ecology sub-branches were prepared. The questions were assessed by 5 lecturers who were…

As understanding of STEM education pedagogy deepens, traditional lecture-based courses evolve to include new philosophies, such as active learning, project-based learning, and inquiry-based learning (IBL). Additionally, hands-on educational experiences at the early stages of an undergraduate program are seminal in propelling students into the…

Chirality continues to intrigue scientists because of its implications in various scientific areas, including the long-unsolved question of its development and link with the origin of life. Chirality plays a significant role in medicine with the advent of chiral drugs and the consequent importance of asymmetric synthesis. For many undergraduate…

Paal--Knorr reactions are a classical method for synthesizing pyrroles, using 1,4-dicarbonyl compound and amine as reactants. It has the characteristics of green chemistry, as only two molecules of water are lost. In this teaching and learning experiment, 2,5-hexanedione and 4-"tert"-butylaniline were used to synthesize…

Colloidal stability is one of the most important criteria in the application strategy of colloidal nanoparticles in the continuous phase. The branches include ecology, involving coagulation as a purification method; medicine as nanocarriers; biology as blood coagulation, etc. A chemist versed in these concepts is a high-performing chemist in…

In the environment, communication among microorganisms is a key aspect of their lives. Through communication, single cells of a microbial population can coordinate their gene expression and, in consequence, their physiology. Quorum sensing systems (QS) are one of these mechanisms that allow this communication through the production and detection…

The use of a multicompartment electrochemical cell for the potentiometric determination of solubility product constants of aqueous I[superscript -], Br[superscript -], SCN[superscript -], and Cl[superscript -] salts of silver is presented. An electrochemical cell presented in this study contained multiple half-cells made of disposable drinking…

The implementation of a laboratory exercise in an undergraduate chemistry course, where students perform a comparison of three different synthetic methods toward [Cu(Cl)(IPr)]-complexes (IPr = N,N'-bis(2,6-diisopropylphenyl)imidazol-2-ylidene), is described. The students are introduced to the continuous improvement of reactions in terms of green…

One of the issues at the heart of transfer is the mobility of credits across institutions--moving credits from one institution to another is a crucial process for the transfer pathway to be a viable option. Credit loss is a critical issue for transfer students enrolled in highly sequential degrees, such as engineering. A student could be set back…

Knowledge of scientific principles and practices is vital to creating informed citizens. At its core, science helps create citizens who question the why and how of things, while also increasing knowledge of the world and beyond. Humans by nature are curious and thrive when they are engaged in learning that relates to real-world situations relevant…
