Techniques and instrumentation that involve fluorescence are used in many careers related to biology and biochemistry. However, due to the expense of instrumentation, the theory and practice of fluorescence spectroscopy is commonly concentrated in instrumental analysis in most curricula, a class rarely required for biology and biochemistry majors.…

In this article, the author presents a Desmos activity where students adjust the measures of angles in radians to reposition a laser and a mirror so the beam passes through three stationary targets. This Radian Lasers activity can be extended to simulate project-based learning (PBL), a pedagogical approach for applying concepts and skills from…

Across science disciplines, light is a common tool for measuring, characterizing, and catalysing molecules and molecular processes. Despite the ubiquity of light-based tools, little research has been done to investigate how students understand light and light-matter interactions (LMI). This topic is typically first introduced in first-year…

There is growing interest in surfing as a recreational activity that may facilitate skill development and improved mental health. However, there remains uncertainty regarding the causal processes through which surfing may improve psychological well-being. With the aim to guide future research, we review potential mechanisms that may underpin the…

It is often necessary to enrich the teaching environment in order for students to learn optics in depth and to interpret the real optical situations with the information they have learned. In this study, a virtual teaching environment was developed using by Algodoo, a 2D simulation software. An eye model was created in order to explain the…

Despite recommendations from science educational standards which claim that science teaching should engage students in scientific investigations the same way scientists practice their profession to discover the unknown, thereby allowing students to actively construct their own knowledge, a growing body of empirical evidence suggests that this may…

Children's brains develop faster in the early years than at any other time in their lives. If you want to make the most of this pivotal period, there is no time to waste. With newly updated research, the second edition of this bestseller provides parents and educators with strategies for building a brain-compatible environment where young learners…

This study aimed to investigate grade-7 students' negotiation during the engineering design process regarding the students' status of argumentation training. The participants were 33 students studying at a public urban middle school in Turkey. They worked in small groups on four engineering design tasks about electricity and light. Data were…

This study aimed to develop a two-tier light concept test to identify student concept understanding of light. The development of the test was carried out through the content validity, construct validity, and reliability test stages using the Item Response Theory (IRT). The sample consisted of 81 students during the second semester at five…

A laboratory experiment that exposes students to fundamental concepts in kinetics and statistical thermodynamics to study systems of great current interest in nanotechnology by employing a foundational technique in physical chemistry is described. A modified commercial flash photolysis spectrometer was used to study photoinduced isomerization…

Knowledge related to photochemistry has been gradually introduced as a part of chemistry courses at both undergraduate and postgraduate levels. However, due to their complex conceptual principles, limited class time, and tedious experimental setup and methodologies, students tend to encounter difficulties in understanding the concepts and…

Light emitting diodes have been used to determine Planck's constant in introductory physics laboratories. One common method relies on the energy of the light emitted by the LED and its relation to the energy gap in the solid of which the diode is composed. However, there could be a problem with the data that are collected for this experiment. For…

Radical chemistry is an essential part of the organic chemistry curriculum. Free radical halogenation experiments provide an excellent opportunity to introduce important topics related to the outcome and mechanism of organic reactions. In this communication, a green photochemically activated benzylic bromination of p-toluic acid is described. In…

In this study, the visual assessment of building facades, which define the boundaries of avenues, were based on the color factor with the aim of revealing its effect on the aesthetic perception of a city. Being part of the façade coloring work implemented in the Province of Antalya, the facades along the Avenues of Gulluk, Yuzuncuyil and Mevlana…

This study provides information about the formation of colours with an experimental activity based on the reflection of coloured lights from pigments. The activity shows the formation of colour in a simple and entertaining way. The lights are reflected by being changed by different coloured pigments. This activity provides an opportunity to…
