Electroanalytical chemistry has been advanced through portable devices, providing methods and sensors for the detection of analytes with high sensitivity and accuracy. This subfield of electrochemistry has the potential to be utilized in industry and analytical quality control, in general. This results in an increasing demand for trained…

Computational and atmospheric chemistry are two important branches of contemporary chemistry. With the present topical nature of climate change and global warming, it is more crucial than ever that students are aware of and exposed to atmospheric chemistry, with an emphasis on how modeling may aid in understanding how atmospherically relevant…

Computational thinking is an essential skill in the modern global workforce. The current public health crisis has highlighted the need for students and educators to have a deeper understanding of epidemiology. While existing STEM curricula has addressed these topics in the past, current events present an opportunity for new curricula that can be…

Sigmatropic rearrangement is one of the main classes of pericyclic reactions, which does not necessarily mean that these rearrangements have a pericyclic mechanism. The allylic saccharin derivative O-cinnamylsaccharin can isomerize into N-cinnamylsaccharin in the polar solvent system toluene/triethylamine in a reaction time of 2 h at 110°C. The…

When new concepts, models, or theories are introduced in a course, their presentation should be accurate, even if depth is not the goal. In a recent publication in this Journal, the Woodward-Hoffmann rules were invoked in the context of a new laboratory experiment, but the associated description was inaccurate. Here we aim to clarify the…

One of the most powerful strategies to support next generation science instruction is the use of instructional models. The Biological Sciences Curriculum Study 5E (Engage, Explore, Explain, Elaborate, and Evaluate) instructional model is arguably the most widely used version of a learning cycle in today's classrooms. The use of the 5Es as an…

What follows is a description of the procedure for and results of a simple experiment on the formation of impact craters designed for the laboratory portions of lower mathematical-level general education science courses such as conceptual physics or descriptive astronomy. The experiment provides necessary experience with data collection and…

The "Mary Rose" was King Henry VIII's favourite battleship, which sank in the Battle of the Solent on 19 July 1545. She was raised in 1982 and brought back to Portsmouth Historic Dockyard where she is now housed in a multiaward-winning museum. The purpose-built Stavros Niarchos Foundation Learning Centre includes a teaching laboratory…

In this article the authors describe what they call their "Snapshots of Science" program. These mini-lessons of science are taught once a week to all students in the school library. Over the last two years, they have been working to extend the experiences students have in their science classroom into the library. Each week, students…

This opinion piece paper urges teachers and teacher educators to draw careful distinctions among four basic learning goals: learning science, learning about science, doing science and learning to address socio-scientific issues. In elaboration, the author urges that careful attention is paid to the selection of teaching/learning methods that…

Changes in the National Curriculum for England in 2014 included the introduction of levers, gears, and pulleys into primary science. Although simple mechanisms had been part of the design and technology (DT) curriculum for some time, it was the first time that the science behind the mechanisms had been included at the primary school level. These…

Young children love to draw, and should be encouraged to explore drawing as a communication tool. Drawing is a means by which children can express their thoughts, interests and feelings, long before they learn to write. We know that: "children's drawings are vehicles for expression and communication" (Chang, 2012, p. 187). This form of…

Well before the Next Generation Science Standards became final last month, teachers in pockets around the country were already exploring the vision for science education espoused by the document and bringing elements of that approach to the classroom. The new standards call for bringing greater depth to K-12 students' understanding of the subject…

This article focuses on some of the intersections of two worldviews: Western modern science and a Buddhism-based way of life in Thailand. It enters the debate on the place and practice of Indigenous forms of knowledge and the clashes with formal science education curricula. Our goal is "balanced bi-gnosis": the possession of, and…

A rigorous K-12 science education builds student knowledge in core scientific content and equips students to analyze problems, use evidence, and investigate solutions. The education requirements of careers across the economy are increasing and all students--regardless of whether they pursue science as a career--need greater proficiency in the…
