Santos, João H. P. M.; Brumano, Larissa P.; Pessoa, Adalberto, Jr.; Rangel-Yagui, Carlota O. – Journal of Chemical Education, 2020
Protein PEGylation refers to the covalent binding of polyethylene glycol (PEG) moieties to a protein and has been increasingly applied, mainly in the biopharmaceutical industry. This technique may increase bioavailability and stability by decreasing immunogenicity and proteolytic attack. Given the industrial interest and the relevance of this…

Kuntzleman, Thomas S.; Annis, Jezrielle; Anderson, Hazel; Kenney, Joshua B.; Doctor, Ninad – Journal of Chemical Education, 2020
When Mentos candies are dropped into a bottle of Diet Coke, a foamy fountain jets out of the beverage container. It has previously been argued that ingredients found in Mentos candies significantly enhance this fountaining effect. Other previous work has demonstrated that the kinetics of foam production can be quantitatively monitored using a…

Ladino, L. A. – Physics Education, 2020
In this work we study the motion of a small metal ball along an inclined multi-slotted track. Specifically, the effect of the slot width on the ball speed at the lower part of the track is analyzed in detailed both analytically and experimentally. Experimental results are in satisfactory agreement with the theoretical model.

Gomes, Mário S. M. N. F.; da Silva, Pedro Pereira; Silva, Manuela Ramos; Martín-Ramos, Pablo – Physics Teacher, 2020
This paper describes an experiment with two touching rotating disks, whose movement is followed by video analysis. Within the disks' movements, there are intervals with sliding and intervals without sliding, that is, intervals with frictional forces between the touching surfaces and intervals without it. This system configuration allows for…

Borish, Victoria; Lewandowski, H. J. – Physical Review Physics Education Research, 2023
As quantum information science and technology (QIST) is becoming more prevalent and occurring not only in research labs but also in industry, many educators are considering how best to incorporate learning about quantum mechanics into various levels of education. Although much of the focus has been on quantum concepts in nonlab courses, current…

Boublil, Shachar; Blair, David; Treagust, David F. – Teaching Science, 2023
The demand for improving student interest in science has increased efforts toward teaching Einstein's theory of general relativity in schools. Research has already shown that teaching Einsteinian gravity at the secondary level is feasible, however, appropriate resources must be readily available for science teachers to make Einsteinian gravity…

Ibarra, Luis Exequiel; Foresto, Emiliano – Journal of Biological Education, 2023
Flow cytometry has become an important tool in the fields of veterinary, medicine, and biological sciences in general. However, in the introductory and even in advanced university degree courses, students do not have many opportunities to be in contact with this type of technology. This situation motivated us to design a simple and inexpensive…

Sieg, R. Drew; Hubbard, Joanna K.; Penczykowski, Rachel M.; Williard, Madison; Dwyer, Zachary A. – Science Education and Civic Engagement, 2023
Providing safe access to functional field experiences during the early stages of the COVID-19 pandemic was a distinct challenge. However, these experiences are critical to train students in ecological methods and provide an opportunity for open-ended, authentic research. Here, we report on a multiweek lab designed for an introductory ecology…

Berg, Stephanie A.; Moon, Alena – Chemistry Education Research and Practice, 2023
Both graph comprehension and data analysis and interpretation are influenced by one's prior knowledge and experiences. To understand how one's prior knowledge and experiences interact with their analysis of a graph, we conducted think-aloud interviews with general chemistry students as they interpreted a graph to determine optimal conditions for…

Wye, Steven – Physics Education, 2023
During the COVID-19 pandemic and subsequent lockdown, both schools and universities faced significant challenges in moving teaching from an in-situ setting to a remote one, this included laboratory experiments. This paper presents an experiment developed to use a phone's in built pressure sensor, common to most smart phones. By using this sensor…

Carrie Ann Sharitt; Michael J. Vanni – American Biology Teacher, 2023
Many high school students learn about nutrient cycling during biology, environmental science, and agriculture classes. These lessons often focus on soil and plants, and nutrient cycling is usually taught independently from climate change. Scientists know that animals, including fish, can have strong effects on nutrient cycling (i.e., nitrogen and…

Ayfer Mutlu – Journal of Science Learning, 2023
This study investigates the effectiveness of using a REACT strategy instruction enriched with guided inquiry-based experiments to improve 7th-grade students' understanding of mixtures compared to conventional teacher-centered instruction. A convergent parallel mixed-method design was used, and 39 middle school students were divided into…

Sierra McCormick; Jodi L. Davenport; Anna N. Rafferty; Sandra Raysor; Jacklyn Yani; David Yaron – Journal of Chemical Education, 2023
The Next Generation Science Standards encourage students to develop the reasoning and practice skills of scientists. Rather than promoting rote memorization, teachers engage students with real-world phenomena and prompt students to think critically. ChemVLab+ is a series of freely available, online modules that require students to reason like…

Jingjing Qiu; Anneke Moeller; Janet Zhen; Hansen Yang; Lily Din; Nicole Adelstein – Journal of Chemical Education, 2023
An integrated inorganic chemistry laboratory experience focusing on heterogeneous electrocatalysis with nickel (Ni)- and cobalt (Co)-based electrocatalysts is designed for upper-division, major-level chemistry students. In this laboratory, students will be guided through the fabrication of an indium tin oxide (ITO)-coated glass working electrode,…

Jinchang Liu; Qin Liu – Journal of Chemical Education, 2023
The COVID-19 epidemic adversely impacted chemical engineering experiments(CEEs). Students underwent online learning, i.e., software simulation of the CEE course, instead of laboratory learning. A questionnaire survey revealed that students exhibited low enthusiasm for online learning, showing that online courses cannot ensure learning quality.…
