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…

An undergraduate laboratory was developed as part of the Drugs for Neglected Diseases "initiative's" Open Synthesis Network. This activity aimed to develop new compounds efficacious against visceral leishmaniasis. Students successfully synthesized, purified, and characterized ten different benzoxazole amides that were sent for biological…

Moya, Antonio Angel – Physics Teacher, 2022
Resistor--capacitor (RC) circuit labs help students, but most courses don't include them because of complications and cost. This work presents an easy and inexpensive Arduino-based lab on the charge and energy transfer between two capacitors with different values of the initial electric charge when they are connected through a resistor. Capacitors…

Electrochromism encompasses reversible changes of material's optical properties (color, opacity) under the influence of an external electric current or applied voltage. The effect has been known for decades, but its importance continues to grow due to the rapid development of smart systems and the accompanying demand to build devices that consume…

Patrick I. T. Thomson; Paul Lamie – Journal of Chemical Education, 2022
This work further implements the "elements of inquiry" approach in a first-year undergraduate laboratory course, in a two-part inquiry sequence. In the first part of the sequence, students iteratively develop a "best-practice" TLC procedure. In the second part, students iteratively optimize a simple organic reaction using TLC,…

Dilek Özalp – International Journal of Science and Mathematics Education, 2025
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…

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…

Puntambekar, Sadhana; Gnesdilow, Dana; Dornfeld Tissenbaum, Catherine; Narayanan, N. Hari; Rebello, N. Sanjay – Journal of Research in Science Teaching, 2021
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…

Manninen, Marianna; Vesterinen, Veli-Matti; Vainio, Anna-Kaisa; Korhonen, Heidi; Karonen, Maarit; Salminen, Juha-Pekka – Journal of Chemical Education, 2021
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…

Ürek, Handan; Özdemir, Erdogan; Coramik, Mustafa – Physics Education, 2021
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…

Leblond, Louis; Hicks, Melissa – Physics Teacher, 2021
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…

Konkankit, Chilaluck C.; Marker, Sierra C.; Bigham, Nicholas P.; Dale, Darren S.; Zax, David B.; Lorey, Daniel R., II; Wilson, Justin J. – Journal of Chemical Education, 2021
There currently exists a significant deficiency in the nuclear chemistry workforce within the United States, despite its importance in areas of medicine, national security, and energy. Poor coverage of this topic across many chemistry departments at the undergraduate level likely contributes to this shortage. Increasing interest and hands-on…
