We constructed a low-cost experimental kit consisting of a compact 532-nm diode laser, optics, and optomechanical components that arrange on a small honeycomb breadboard. The kit is flexible enough to construct five typical wave optic experiments, e.g., double-slit interference, Michelson and Mach-Zehnder interferometers, diffraction, and Malus's…

Enzyme kinetics is an essential topic in undergraduate Biochemistry courses. A laboratory work that covers the principal basic concepts of enzyme kinetics in steady state is presented. The alkaline phosphatase catalyzed reaction of phenyl-phosphate hydrolysis was studied as a model. The laboratory experience was designed to reinforce the concepts…

Building a virtual laboratory for teaching and learning is a highly complex process, incorporating diverse areas such as interaction design, visualisation, and pedagogy. This article focuses on the production and implementation issues that were found in the comparison of two different virtual laboratory projects, and discuss which design…

In this study, we made a simple electronic electroscope called a 'polarity detector' which can determine the type of electric charge on any objects. We used the polarity detector in some student experiments in the physics laboratory. For example, when we applied a plastic rod to a piece of fabric made of wool, we could easily determine that the…

We describe a 2 h general-chemistry experiment that introduces college students not only to the concepts, synthesis, and applications of nanomaterials at an early stage but also the use of a spectrophotometer for quantification and unknown determination based on Beer's Law. The procedure involves students (1) preparing a nanocomposite by…

An integrated and research-focused laboratory experiment is developed to introduce the "antenna effect" occurring in luminescent lanthanide complexes to students. Students synthesized a lanthanide metal-organic framework (Ln-MOF) with the formula of [Eu(BTPCA)(H O)]·2DMF·nH[Subscript 2]O (Eu-BTPCA, H[subscript 3]BTPCA =…

Engaging in argument from evidence is a fundamental science practice. However, preservice elementary teachers have difficulty constructing arguments. They need effective experience with argument construction in science. Written argumentation is crucial in the process of science learning. One of the approaches for learning science through…

This study explores the ways in which embodied creativity is conceived and implemented in french schools through the study of a corpus of professional articles published since the 1960s in a journal dedicated to physical education. The analysis focuses on pedagogical experiments to foster bodily creativity carried out in primary schools, as part…

Virtual laboratories (VLs) enable students to experiment, analyze data, or interact with digital content in a nonphysical space. VLs include simulations, electronic notebooks, videos, and augmented reality. As part of the "VL Project," comprising five academic institutions in Ireland, we sought to determine how VLs might enhance…

This study embarked on the development of a comprehensive Junior High School Biological Inquiry Experiment Manual. This manual was utilized in a research initiative involving 30 students in the control group and an equal number in the experimental group. Rigorous data analysis techniques, encompassing mean values, standard deviations, paired…

In this article we explore the challenges and rewards of a multi-year, multidisciplinary, multi-institutional approach to collaborative teaching and learning. What does it mean to teach across disciplines and what might this look like for our students who are emerging professionals from very different fields of study? What are the challenges of…

Research exploring students' learning from physical and virtual labs has suggested that on the whole, students learn science content just as well, if not better from virtual labs as they do from physical labs. However, the affordances of physical labs might support the learning of specific skills and competencies that are just as crucial for…

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…

Scientific laboratories are among the most challenging course components to integrate into online instruction. Available technology restricts the design and nature of experiments, and it can be hard to replicate the collaborative lab environment where frequent and immediate instructor feedback is the norm. Here we report on technological and…
