Isothermal titration calorimetry (ITC) is the method of choice for thermodynamic binding profiling. As a label-free in-solution technique, ITC experiments do not require modified or immobilized proteins or ligands and hence can be performed under close-to-native environmental conditions. It directly follows the released heat of the molecular…

Normal phase thin layer chromatography is a widely taught technique in undergraduate organic chemistry laboratory courses. To understand how the technique works, students must have a strong conceptual understanding of polarity and intermolecular forces. Unfortunately, many students have misconceptions regarding how polarity and intermolecular…

Infrared (IR) spectra of biologically derived materials display distinct absorption bands correlating to individual macromolecules: protein, polysaccharide, lipid, and nucleic acids. A series of experiments aimed at teaching qualitative bioorganic spectroscopy using attenuated total reflectance (ATR) Fourier transform infrared (IR) with biological…

Student participation in interactive outreach programs focusing on anatomy has been shown to have a positive impact on learning and healthcare career aspirations. This article describes the Anatomy Outreach Program held at the Physical Therapy Center and Gross Anatomy Lab on the campus of the University of Central Arkansas. Physical therapy (PT)…

A mixture of salt water and isopropyl alcohol is immiscible, forming two separate liquids with the organic layer on top and aqueous layer on bottom. When universal indicator is added to such a mixture, all of the indicator compounds in the universal indicator preferentially dissolve in the alcohol--except for phenolphthalein at high pH. Mixtures…

Recent advances in Artificial Intelligence (AI) have brought society closer to the long-held dream of creating machines to help with both common and complex tasks and functions. From recommending movies to detecting disease in its earliest stages, AI has become an aspect of daily life many people accept without scrutiny. Despite its functionality…

Microfluidics has attracted widespread interest in the fields of chemicals, materials, pharmaceuticals, biology, etc. Integrating low-cost automation based on open-source hardware/software to improve lab security and reduce time consumption is demanded in microchemical processing. In this work, we developed a "do it yourself"…

This study aimed to examine whether withholding answers coupled with physical manipulation of material strengthened by the self-explanation effect (SEE) contribute to the development of a deeper conceptual understanding and retention of learning about motion content in a hands-on (HO) learning environment. The correlation between students'…

Nanozyme is a kind of mimetic enzyme possessing unique properties of nanomaterials and catalytic functions of natural enzymes. The nanozymes have the characteristics of high catalytic efficiency and good stability and are widely utilized in medicine, chemical industry, food, agriculture, and environment. This laboratory experiment is designed for…

A laboratory experiment is proposed, wherein students fabricate a glucose fuel cell, use it to operate a solar motor, and investigate its performance. First, a fuel cell catalyst is prepared by plating palladium on two nickel wire meshes using an aqueous palladium chloride solution containing sodium dodecyl sulfate, an anionic surfactant that…

Southern blot analysis is an important molecular biology technique for identifying a specific sequence in DNA samples. Although it is no longer used extensively in recent years, the steps and underlying principles of Southern blot are applicable to modern biology. High sensitivity and limited background are keys to successful Southern blots,…

Electrochemistry represents a powerful sustainable method for chemical synthesis; however, its widespread application is limited due to the lack of exposure and appropriate basic training of synthetic chemists and engineers in electrochemistry and electrochemical engineering. The introduction of diverse laboratory practices to the current…

The great development of high-throughput molecular biology techniques and the consequent generation of massive data have made Bioinformatics essential for undergraduate Bioscience students. The importance of this scientific discipline is evidenced by the huge number of specialized publications, tools, and databases available. Training in…

The mastery of the ability to identify and describe plant morphology is an essential aspect of studying biology. The skill of describing plants can be developed through diverse learning resources, including textbooks and contextual materials. Therefore, this study aims to determine students' ability to describe the morphology of plants using a…

Bodily engagement with the material and sociocultural world is ubiquitous in doing and learning science. However, science education researchers have often tended to emphasize the disembodied and nonmaterial aspects of science learning, thereby overlooking the crucial role of the body in meaning-making processes. While in recent years we have seen…
