Marx, Jeffrey – Physics Teacher, 2023
The various aspects of projectile motion have been analyzed many times in this journal. As a sample, over the years, authors have investigated particular details of the path of a projectile and different situations for launching projectiles. Others have written about a nifty way to determine the maximum height of a projectile, finding the range of…

Schilling, Ellie; Sandman, Joy; Sait, Rida; Stich, April; Baryeh, Kwaku; Blankson, Gifty – Journal of College Science Teaching, 2023
A lateral flow assay was designed and optimized as an independent study project that aimed to develop an assay for the qualitative detection of troponin assay. Lateral flow assays (the classic example being a pregnancy test) have the advantage of being rapid, specific, and user-friendly. They are composed of an absorbent pad, a nitrocellulose…

Louca, Loucas T.; Zacharia, Zacharias C. – Journal of Research in Science Teaching, 2023
Despite its proven added value, modeling-based learning (MbL) in science is not commonly incorporated into the early grades. Our purpose in this descriptive case study was to enrich our understanding of how kindergarten children enact MbL by examining these children's constructed models and their accompanying oral descriptions of their models. For…

Clark, Ted M.; Dickson-Karn, Nicole M.; Anderson, Ellie – Journal of Chemical Education, 2022
Student performance calculating the pH of a strong acid or strong base solution before and after instruction in general and analytical chemistry courses was investigated using open-response questions in which a pH equation was not provided. Prior to instruction, students in both classes scored very low. General chemistry students lacking prior…

de Graaf, Ruvan; Crough, Kiernan; Steiner, Isaac; Hudson, Reuben – Journal of Chemical Education, 2022
A culinary exploration of the role of CO[subscript 2] in leavening is described. This demonstration substitutes dry ice for chemical leaveners in order to achieve the same pancake fluffiness. Under the universal framework of food and cooking, we developed this activity to bring aspects of phase transitions and chemical transformations to a broad…

Doan, Andy – Schools: Studies in Education, 2022
The article tells stories of how meaning can occur and be made in educational settings, using insights from the work of Patricia Carini and John Dewey to reflect. Dewey's description of what makes an experience meaningful and Carini's calls for an education grounded in meaning and value, along with the role of the Prospect descriptive processes as…

Markwick, Andy – School Science Review, 2022
There are several 'cool' mechanisms that result in materials luminescing or emitting light. Artificial luminescence has often been created by mimicking nature and there are many examples of applications in society. It is very likely that most of your students will have observed luminescence in one form or another, such as glow sticks,…

Nalence, Eugene Edward – Physics Teacher, 2022
There are hundreds of satellites in orbit around Earth. Readily available data about them can be a treasure trove for investigations by students at all levels. Orbital parameters and energy changes can be explored. Many of these satellites transmit signals that can be detected by an inexpensive radio receiver--a scanner--designed to receive FM…

Louw, Marti; Sanford-Dolly, Camellia W. – Science Education, 2024
Scientific observation is a disciplinary-informed way of looking at the world that requires the coordination of domain knowledge and perceptual skills with specialized tools and techniques to systematically identify objects, organisms, specimens, or phenomena of interest. Identification is a particular form of skilled observational practice where…

Wei, Bing; Wang, Yaqing – Science & Education, 2021
The term "science practice" has drawn increasing attention in the current science education literature. In this study, the methodology of content analysis was adopted to examine the presentation of science practice in 20 historical cases compiled in a popular science book. Three aspects and eight categories of science practice constitute…

Xu, Huiling; Yan, Xun-Wang; Wang, Yanyun – Physics Teacher, 2022
Aristotle's wheel paradox is a fascinating example of a classical puzzle that can pique a student's interest. The existing explanations in the literature are limited to discussions of the wheel trajectory; in this paper, we study the paradox from the viewpoint of motion decomposition, an approach we consider more intuitive. The motion of the point…

Zuo, Fulin – Physics Teacher, 2022
The electric field inside a uniformly charged long cylindrical shell is a standard example discussed in introductory university physics. The field is zero inside the cylinder; outside of the cylinder, the field behaves like a long wire at the center carrying the same amount of charge per unit length, analogous to that of a uniformly charged…

Manz, Eve; Beckert, Betsy – Science & Education, 2023
Changing where, when, and how objects are studied is central to lab-based science (Knorr Cetina, 1999). Science involves changing the scale of objects--particularly scales of size, time, and intensity--from what is experienced in the world. Similar to investigations conducted in science laboratories, classroom investigations involve…

Naoto Shirasu; Shin'ichiro Yasunaga – Biochemistry and Molecular Biology Education, 2024
Here, we propose a laboratory exercise to quickly determine single nucleotide polymorphisms (SNPs) in human "alcohol dehydrogenase 1B (ADH1B)" and "aldehyde dehydrogenase 2 (ALDH2)" genes involved in alcohol metabolism. In this exercise, two different genotyping methods based on polymerase chain reaction (PCR), namely…

Helen Georgiou – Teaching Science, 2024
Thermal cameras have shown to have utility in secondary school classrooms and undergraduate courses. In this paper, the author argues for their potential in the primary school classroom and presents a range of activities that can be undertaken with thermal cameras (or supplied images). With limited access in mind, the activities in this paper have…
