Heterocyclic compounds are an integral part of research, particularly in the pharmaceutical field. The synthesis of such compounds in an undergraduate laboratory can help students understand the relevance and importance of their field of study. Our experimental activity introduces a novel procedure to synthesize coumarin, a heterocyclic formed by…

The rapid growth of personal electronics has promoted a surge of e-waste worldwide. Among the e-waste stream, waste printed circuit boards (WPCBs) contain a lot of recyclable valuable metals that can incentivize the recycling operation when recovered. This pedagogical exercise demonstrates a simple electrocatalytic metal recovery strategy that…

A laboratory experiment is proposed, wherein students fabricate a glucose fuel cell, use it to operate a solar motor, and investigate its performance. First, a fuel cell catalyst is prepared by plating palladium on two nickel wire meshes using an aqueous palladium chloride solution containing sodium dodecyl sulfate, an anionic surfactant that…

In the ever-changing world based on the needs, curiosity and entrepreneurial drive of the humankind, interest in socio-scientific issues has been increasing every day with the discussion and different approaches in society. It could be suggested that the increase in this interest has been due to both the contribution and damages of these issues to…

Science education is essential for sustainability and prosperity. However, students from rural communities, arguably the future custodians of our environment and significant drivers of our economies, underperform in science education. In Australia, rural students generally lag behind metropolitan students in science achievement and engagement.…

Most of the tools developed in the area of "Science Education" aimed at analyzing either the product or the process of argumentation do not consider the following: (1) arguments are a part of dialogues; (2) dialogues present different objectives; (3) dialogues start from different assumptions; and (4) dialogues shape the roles and moves…

The paper introduces a tool for analyzing the teaching venue (where and how the teaching happens) of science teachers, called Strands of Science Teaching (SST). Its construction was by analogy to the Strands of science Learning, a set of categories of analysis for the science teaching. Based on the concepts of Learning by Inquiry, the aspects of…

The five papers published by Hodgkin and Huxley in 1952 are seminal works in the field of physiology, earning their authors the Nobel Prize in 1963 and ushering in the era of membrane biophysics. The papers present a considerable challenge to the novice student, but this has been partly allayed by recent publications that have updated the…

Robert Collins offers congratulations to Katie Wylie, the recipient of 2022's ASE Alexander Award, which is awarded annually to a woman or group of women who have made a significant contribution to the scientific, technological, engineering or mathematical (STEM) education of girls or women, in situations of scarce resources. He offers a personal…

The ideal gas law, "PV = nRT," is one of the simplest physical laws in nature that is introduced to students as early as in high school and first year in college. In this equation, "P" stands for pressure, "V" is the volume, "n" is the amount expressed in mole, "T" is the temperature in Kelvin…

In this article we present a simple technique for determination of the Young modulus of the material of a metallic ruler using it as a cantilever. This method employs with a slide potentiometer and a digital multimeter. The linear region of potentiometer resistance which is calibrated in terms of length has been used to record the load vs.…

The refractive index of a liquid is known to depend strongly on the temperature gradient of liquids. When a laser beam passes through a transparent material going through thermal diffusion, the light projected onto a screen will be displaced in relation to the thermal diffusivity. A simple apparatus is used to measure the time evolution t of the…

We present an experiment designed to study standing waves in a tube with one closed end. Two smartphones are used, one to emit a sound signal with a chosen frequency and another equipped with a microphone to detect the sound pressure level inside the tube. Due to the finite diameter of the tube, the standing wave node (or antinode) appears…

The purpose of this study is to understand how secondary science teachers conceptualize student science identity and the impacts of this thinking on actions and planning with teaching. Research on how science identity impacts college students is more robust while little research looks at the impacts of secondary science teachers on science…

In the past few decades, chemistry has evolved to interact with various disciplines to synergistically help tackle global challenges. This, in turn, requires that newer generations of chemistry students are trained to be more flexible in accepting and coordinating new concepts. In this experiment, pineapple was used as a key model to allow for the…
