What if "every breath you take, every move you make" (Sting 1983) could be harnessed to produce renewable energy? Triboelectric nanogenerators (TENGs) are state-of-the-art devices researchers are studying to do just that--convert kinetic energy into electrical energy at the source (Saurabh Rathore 2018). This type of electrical energy is…

The coronavirus disease 2019 (COVID-19) has prompted the shift from traditional face-to-face instruction to new methods in online platforms. As national governments enforce public health measures to minimize the risk of the virus' transmission, learning institutions grapple with the new norms in education. Teachers are finding ways to address the…

This research was conducted on students of two senior high schools in Jambi, Indonesia, where the two schools have almost the same characteristics but apply different cooperative learning models, namely the inquiry learning model and the Jigsaw learning model. The purpose of this study was to assess students' attitudes towards physics through the…

The bicycle is one of the greatest locomotive machines ever invented. It is also a perfect vehicle for you to teach some of the ideas that are taught in forces topics to 11- to 16-year-olds. In this article we look at some of the ways in which you can use the bicycle and cycling to provide an alternative and engaging context for teaching some of…

We present a computer-based experiment that simulates the accretion process and generates fluffy aggregates with fractal nature. The Box Counting is performed without the aid of an image processing tool by using the coordinate information of the constituents of the aggregate. A simple algorithm to create aggregate and calculate box-dimension will…

A quantitative experiment where we measure the acceleration of spheres of radius "R" rolling on an inclined U-shaped profile of width "2D" is presented. For a given inclination, we examine the behaviour of four solid spheres having different diameters; in contrast to what is usually assumed to be the case, the experimental…

Using a phenomenological lens, we investigated how online curriculum resources can support secondary science teachers to explore contemporary science practices with their students. The research used a social constructivist theoretical and a hermeneutic phenomenology methodological framework to describe and interpret the teacher/participants'…

Every day we deal with chemistry in various forms, but sometimes we don't see that. An example is biosensors that help us to evaluate health conditions, monitor environmental pollution and ensure food freshness. The most well known (and most widely sold) is the biosensor for blood glucose measurement, used every day by people with diabetes.…

When a new topic is introduced in the curriculum, teachers seek various ways to teach students the related concepts. For the novel topic 'materials' in the revised Dutch curriculum, I developed an experiment in which students determine Young's modulus using a guitar string. The experiment not only covers several concepts related to 'materials' it…

Formal understanding of the nature of science (NOS) has been considered to be a major contributor to nurturing students' scientific literacy. In China, this view has been endorsed in the new standard for high school physics curriculum, which has guided the development of the new generation physics textbooks. Following the analytical framework…

Scientific advances, particularly in evolutionary biology, genetics, neuroscience and artificial intelligence, present many challenges to religious and popular notions of personhood. This paper reports the first large-scale study on students' beliefs about the interactions between science and widely held beliefs about personhood. The paper…

Biology is a subject that contains of many difficult concepts to study. This study aimed to identify Biology topics taught in Senior High School (SHS) which were considered as difficult materials by undergraduate students. The data were gathered by means of a web-based survey from 198 Biology students of 25 universities and 51 Biology education…

Crosscutting concepts (CCCs) are superordinate in the scientific concept system, common across disciplines, and very abstract. These characteristics, with the addition of incoherence in their curricular presentation, can challenge instructors. We designed a modular course based on coherence and conceptual understanding. The course structure was…

This high school life science unit introduces students to the intersection of science, economics, geography, and culture through the current practices of palm oil cultivation in the tropics. For this article, the authors travelled to Sabah Province, Malaysia, to visit palm oil plantations, conduct interviews, and collect resources to help students…

Experimental results are presented on the collision of a superball with two different wood blocks. The results are in reasonable agreement with a simple collision model where kinetic energy is conserved, but better agreement is obtained if a small loss of kinetic energy is assumed, as observed. The physics is slightly more complicated than the…
