Thomas Graham discovered the law that bears his name while studying gas diffusion into air and other gases. He also found that the same relationship held with gas effusion, the movement of gases through a pinhole into a vacuum. Modern understanding of diffusion and effusion is based on kinetic-molecular theory, and it is generally accepted that…

This study explores emergent reflective structuration as a new form of shared regulation. The purpose is to support students in taking on high-level epistemic agency as they co-configure dynamic inquiry pathways that unfold over long periods of time. With the teacher's support, students not only regulate their inquiry and collaboration following…

Individuals have different opinions and views on many socio-scientific issues such as stem cells, influenza vaccine, cloning, nuclear power plants, and organ transplantation that affect social life. Scientific attitudes and scientific literacy of individuals can affect their approach to socio-scientific issues. This research aims to reveal how…

Planetariums have been used for a long time in astronomy education. Due to some disadvantages of permanent planetariums, it is seen that portable planetariums have become popular in recent years. Portable planetariums, due to their easy set up in anywhere, offer opportunities for those students studying in the regions where there are not…

This article presents findings from a doctoral study which examined the ways teaching teams in six New Zealand early childhood education (ECE) centres fostered and supported young children's scientific experiences. The focus of this article is the pedagogical practice of using provocations to facilitate scientific opportunities. The way…

Research has demonstrated that gesture produced during conversation can provide insights into scientific thinking and can aid scientific communication in adults and school-aged children. However, to date, there has been a limited exploration into the role of gesture in supporting young children's science communication, and how this is underpinned…

In the study, the effect of Predict-Observe-Explain (POE) activities carried out within the scope of argumentation-supported learning method on the detection of the conceptual understandings of the pre-service science teachers about "Solutions: Dissolving-Melting" was examined. Based on this main purpose, a case study was applied in the…

A quick look at the Native American academic achievement gap illustrates Native American students are more likely to live in areas of poverty, less likely to graduate from high school, and less likely to go on to college (Annie E. Casey Foundation 2017; 2018). The Next Generation Science Standards and others recommend that teachers trained in…

The Centre for Industry Education Collaboration (CIEC) team at the University of York has carried out research and evaluation into the impact of their resources and programmes since the programme began in 1996, to ensure that all their programmes -- are improved to meet the changing needs of both schools and companies. Furthermore, their research…

This paper presents preparations, execution and reflection on results for the physics part of a CSI task for the European Union Science Olympiad 2010, taking place at the University of Gothenburg. The participants were required to make a graph of the cooling of a swede ("Brassica napus"), as a proxy for the cooling of a murder victim,…

There has been a growing awareness that graphing is an essential part of the science curriculum. While much research has focused on student conceptions and abilities regarding graphical representations, only few studies have investigated what teachers think about them and how they use graphs in science class. The purpose of this study is to…

As the use of plastics expands, microplastic concentrations increase in aquatic environments and negatively impact water, soil, and animals inhabiting these areas. Microplastic research frequently incorporates citizen science to assist in data collection and environmental education. These projects provide opportunities for greater societal…

Scientific Data Analysis Toolkit (SDAT) is a rigorous, versatile, and user-friendly data analysis add-in application for Microsoft Excel for Windows (PC). SDAT uses the familiar Excel environment to carry out most of the analytical tasks used in data analysis. It has been designed for student use in manipulating and analyzing data encountered in…

The author has acquired a yellow laser with the specific wavelength of 589 nm. Because this is the first time such a laser has been discussed in this journal, I feel it is appropriate to provide a discussion of its function and capabilities. Normal laser safety should be employed, such as not pointing it into eyes or at people, and using eye…

Open-ended problems are a very effective tool for engaging student interest. In this paper, we report a physics activity that provides insight into the lifestyle of theropod dinosaurs. This activity generates great enthusiasm among the students since virtually everyone is interested in dinosaurs. In the spirit of the "spherical cow"…
