This manuscript introduces a novel General Chemistry experiment designed to incorporate modern instrumental methods and bioinspired materials in the context of marine environments and sustainability. The experiment explores the influence of collagen on the formation of calcium carbonate (CaCO[subscript 3]) polymorphs over two 2 h lab sessions,…

The free radical chlorination of an alkane experiment is often used in the undergraduate laboratory curriculum to introduce students to the free radical mechanism, substituent effects, intermediate stability, and the relative reactivity of radicals. In this experiment, students monochlorinate multiple alkanes and analyze the reaction mixture using…

Keto-enol tautomerism is a special example of structural isomerism. In this experiment, 6-chlorofulvene is predominantly yielded during the chlorination reaction of 6'-hydroxyfulvene with POCl[subscript 3] in the presence of DMF. The high regioselectivity of this reaction is dominated by intramolecular hydrogen-bonding and steric hindrance,…

In this brief experiment, students create a superhydrophobic surface as an application of polar--nonpolar interactions and redox chemistry. Half of a zincgalvanized steel strip is coated in copper nanoparticles through electroless deposition. A layer of nonpolar octadecanethiol is added to half of that copper surface. Students classify the three…

A laboratory activity is described for senior high school or first year undergraduate level students that illustrates key concepts linked to extractive metallurgy. This experiment demonstrates preferential binding of a methoxyphenolic oxime ligand to Cu[superscript 2+] in the presence of other transition metal ions in aqueous solution. The…

We have developed a stereo vision system for observing real objects for experimental physics demonstration. The stereo vision observes objects from two different points of view. An observer can identify the distance and velocity of an object based on at least two different points of view. This paper demonstrates our comprehensive observation in a…

We propose an experiment in which the sound of a drumroll is recorded and analysed according to a simple mechanical model in which the inelastic restitution coefficient of the collision between the stick and drum surface, as well as the ongoing kinematics of the drumstick, are considered. The agreement shows that this model is well suited for…

A cost-effective method has been developed with utmost efficiency for the determination of density of a liquid. The experimental setup for this purpose is a Polyvinyl chloride (PVC) cylinder fitted with an overflow spout, a volume measuring cylinder, a wooden block along with a hook and a known mass taken from scientific weight box. For this…

In diffraction experiments, natural gratings often create uncommon diffraction patterns compared with those resulting from manufactured gratings. This study analyzed a unique diffraction pattern obtained by a grating from a flying termite wing. A ring-like diffraction pattern was formed because of the grating morphology from a flying termite wing,…

Plants encounter several different threats that affect their well-being during the spring. With chemistry, plants may defend themselves from, for example, excess UV-radiation and herbivores. The defense compounds between plant species vary, which makes it possible to utilize chemistry in identifying the plant species. In this laboratory…

The target of this study is to determine the minimum angle of deviation of a prism which is one of the optical experiments. Thus, the aim is to state the refractive index of a prism. In this context, the Tracker program, which might also be utilized in terms of distance education purposes, was preferred. The videos of the experiments were recorded…

The present investigation aims to analyze the knowledge levels and chemical representation levels of pre-service primary school teachers (PPSTs) on the experiment of distillation. For this purpose, the cross-sectional survey technique, one of the quantitative research designs was employed. The study was carried out at a Faculty of Education in the…

CACAO (Chocolate Across the Curriculum and Outreach) is a vertical curriculum augmentation designed to help students across the ChE undergraduate program. The students use a chocolate-based food engineering lab to make connections between core chemical engineering topics using hands-on and project-based learning. Costs to create this component are…

Molecular imprinting technology holds significant potential for applications in chemical analysis and detection. In order to integrate the fundamental knowledge of polymer chemistry, electrochemistry, and analytical chemistry with practical applications and cutting-edge research, we proposed a comprehensive experiment of the preparation,…

We present a simple smartphone-based protocol for the estimation of the critical micelle concentration (CMC) of surfactants. The protocol is based on contact angle measurements from the smartphone-captured images of differently concentrated surfactant solution droplets mounted over a naturally existing or chemically synthesized superhydrophobic…
