Plastic recycling has gained increasing attention due to the negative impacts of improper plastic waste management and its end-of-life outcomes. Despite growing research and educational efforts on sustainability, the integration of community service into student learning experiences remains limited. To address this gap and promote sustainable…

This study investigated the interrelationships among science process skills (SPSs) developed through home-based experiments (HBEs) and examined the correlation between SPS and science literacy (SL) among middle school students. Employing a qualitative correlational design, the study involved 77 seventh-grade students in Aceh Province, Indonesia.…

Computer-supported collaborative learning (CSCL) offers a modern setting for learners to engage in meaningful (meta)cognitive and socioemotional interactions. However, the task design, not technology alone, significantly shapes students' learning interactions. This study investigates how a conceptual physics task and a hands-on robotics task…

It is well known that allowing students to put theory into practice is beneficial to consolidate knowledge and to better memorise the topics that are discussed in class. Furthermore, practical work is a valuable asset to stimulate students' attention and represents one of the keys to the success of the scientific experience in school. Didactic…

A series of models in the Educational CAD Model Library can be used to reconstruct mechanical animation machines such as the Praxinoscope and related animation mechanisms. Hands-on experiences can be used to enhance understanding of historical invention processes and related science concepts. Foundational concepts of visual perception are…

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…

Metal-organic frameworks (MOFs) are porous materials composed of metal ions and organic ligands. These materials have garnered significant attention due to their wide-ranging applications, such as the capture of hazardous molecules, catalysis, production of value-added compounds, and detection of ions or molecules in water. Despite their immense…

In this second-semester organic chemistry lab experiment, students work collaboratively using a combination of chemical synthesis and NMR spectroscopy to investigate the diastereoselectivity associated with the Meerwein-Ponndorf-Verley (MPV) reduction of two ketone substrates having carbonyl groups flanked by an [alpha]-chiral carbon with…

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)…

Electrochemical characterization techniques are essential for studying and developing advanced materials across various fields, from corrosion science to energy storage, photovoltaics, and bioelectrochemistry. However, these techniques are often under-represented in educational curricula. This practical guide with a hands-on laboratory experiment…

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"…
