A single-slit diffraction experiment in an introductory physics laboratory is generally comprised of a rectangular slit and a laser source. The laser beam is sent to the slit producing the well-known diffraction pattern on the screen. This paper proposes a simple modification of the single-slit diffraction experiment to increase student attention…

NMR spectroscopy is a powerful spectroscopic tool that not only allows the determination of structures after synthesis, as usually explained to students of Organic Chemistry, but also is useful in many other fields such as medicine imaging, real-time industrial processes, material sciences, or metabolomics. In this experiment, students performed a…

Laboratory astrophysics and astrochemistry are emerging fields highlighting the importance of laboratory simulations and experiments to benefit remote observations. In particular, ice mixtures found in the outer solar system may offer insight into the early evolution of organic molecules. H[subscript 2]O-ice mixtures containing other species such…

The educational system is presently undergoing a substantial change to improve the teaching-learning process of all engineering domains. This includes the utilization of user-friendly simulation tools as part of the laboratory for an enhanced practical experience on a virtual platform. Owing to the advantages of virtual experimentation,…

Isoenzymes are variant forms of the same enzyme activity that exhibits different tissue distribution. When cells are damaged, intracellular content leaks into the blood stream, making them potential biochemical markers. Undergraduate health sciences students are expected to interpret laboratory findings of serum levels of biochemical markers and…

The chemistry of metal-organic frameworks (MOFs) has the potential to introduce high school and undergraduate students to the fundamental chemical principles of structure and bonding, enhance the development of skills in synthesis and crystal growth, and promote hands-on experience with gas capture and host-guest chemistry of emerging materials…

Undergraduate laboratory courses can provide opportunities for students to participate in science practices. This requires rethinking both curricula and instruction. Science practice--based courses require students to be positioned as epistemic agents, implying a shift in instructor role. Teaching assistants (TAs) are the primary instructors for…

The problem addressed through this study was the absence of a critical examination of laboratory exercises used with first-year nonbiology majors and the deployment of virtual laboratories in the biology department at the project site university without critical analyses associated with the efficacy of virtual labs. Grounded in Mayer's cognitive…

Brain dissection is typically an important part of teaching neuroscience in health professional programs. This results in the need to effectively remove brains, which is often performed in a gross anatomy laboratory in the same curriculum. The aim of this study was to determine the most effective method of brain removal based on the time required…

While the three laws of conservation of energy, momentum, and angular momentum are all mentioned in introductory textbooks, there are few experiments through which students can investigate the conservation of angular momentum. Most experiments consist of collisions between rotating disks, in which one disk is dropped on another, or in which the…

In order to make up for the shortage of scientific research experiments and teaching in land-based engine room laboratory, a simulation system is designed and developed using B/S mode to simulate scientific research experiments, teaching and operation processes, and designed algorithms to simulate the propulsion characteristics of the main…

Quantum dots are colloidal semiconductor nanocrystals that display size-dependent electronic and optical properties. These materials are a visual demonstration of a quantum-mechanical effect. Here we present a laboratory exercise for undergraduate/Bachelor students as an introduction to colloidal nanocrystals and quantum dots. The students…

In this paper, we present a concise and technique-heavy route to the synthesis of dimedone for a second-year organic chemistry curriculum. Our preparation of dimedone guides students through a Michael addition followed by a Dieckmann cyclization, basic ester hydrolysis, and thermal decarboxylation, while allowing time for mechanistic discussion…

Despite the growing importance of nanomaterials in numerous industries, most undergraduate chemistry students are unlikely to encounter characterization techniques common in the field during their education. Scanning electron microscopy (SEM) is a common technique for materials characterization widely used in careers chemistry students are likely…

The synthesis of a [2]rotaxane through three- or five-component coupling reactions has been adapted to an organic chemistry experiment for upper-division students. The experimental procedure addresses the search for the most favorable reaction conditions for the synthesis of the interlocked compound, which is obtained in a yield of up to 71%.…
