Urgent action is needed across the world to combat climate change and its impact on the social, economic, and environmental well-being of humans and the planet. This important topic is one that is a priority for integration into chemistry classrooms, laboratories, and outreach efforts. It connects strongly to foundational chemistry concepts and…

Photochemical reactions are the reactions that are induced by light. Many of these reactions are found in natural processes, including photosynthesis and the formation and decomposition of ozone in the atmosphere. Classroom demonstrations are effective in enhancing students' learning and retention. Herein, we have developed a simple demonstration…

Syntheses of analogues of historical indigo and Maya blue pigments using an inquiry-based approach are presented. Derivatives of indigo were synthesized (in particular Tyrian purple) and used as vat dyes for dyeing cotton or wool fabrics or mixed with a sepiolite clay to create new hues or colors of Maya blues using a green chemistry hydrothermal…

An active-learning approach was employed in a project for our chemistry major students on the synthesis of biodiesel (BD) from an Amazon region oil. The project, involving activities in class and in the laboratory, was given during 8 weeks of the spring semester of 2022. The students were asked about their previous contact with the synthesis and…

Active learning strategies engage students productively in the process of learning through problem-solving activities and discussions, over and above the routine method of listening passively to the instructor. This work highlights the redesign of a medicinal chemistry course by augmenting traditional lectures with active learning sessions in…

Studies on the efficacy of the flipped classroom structure have become more prevalent in the chemistry education research literature over the past 10 years, and the body of research that has been compiled appears to indicate flipped classroom structures positively impact student learning outcomes relative to "teaching as usual"…

There is a gap between the importance of certain archeological material sources and their perception, both by professionals and by the general public. Textiles, for example, are essential to understanding practices that marked daily life and rituals in the past, but they have often been extremely degraded over time, particularly in temperate…

Water electrolysis, a well-known and simple experiment, confirms that a water molecule comprises hydrogen and oxygen atoms. In this experiment, hydroxide or hydrogen ions generated from each electrode were identified using an indicator based on the assumption that electrodes, electrolytes, and indicators do not participate in the water…

Enzymes, enzymatic kinetics, and enzyme inhibition are topics covered in undergraduate biochemistry textbooks, having perceptible relevance to everyday life. The experimental use of enzymes involved in basic physiologic processes may be of utmost pedagogic interest because they bring evidence on how a significant number of drugs are used to…

Electron configuration provides insight into the chemical behaviors of elements and is an important concept for students to master in introductory chemistry. To better strengthen undergraduate students' mastery of electron configurations of atoms and ions, we designed a novel, interactive chemistry game called ChemisTree that uses active-learning…

Since 2012, when triboelectric nanogenerators (TENGs) were first reported by Wang and co-workers, various applications have taken advantage of their ability to transform mechanical energy into electrical energy. TENG applications cover many fields, including electronics, physics, materials science, and engineering. The differences in the language…

The educational game "Make or Take" is designed to approach the notoriously challenging topic of organic synthesis in an entertaining and engaging way. In this unique, two-part game, teams of students are given identical lists of several synthetic transformations, each requiring multiple steps to complete. During the first part of the…

This paper describes the creation of a theme-based first quarter, of a two quarter sequence, general chemistry laboratory course following an argument driven inquiry format and employing specifications grading. The course contains four, two-week projects investigating the chemistry of a popular sports drink. The sugar content, dye concentration,…

Atomic orbitals represent an essential construct used to develop chemical bonding models, upon which other more advanced chemistry topics are built. In this article, we share a series of active-learning activities and a gamified approach to develop students' representational competence about atomic orbitals and to engage students in learning the…

Multitouch experiment instructions (MEIs), implemented as interactive eBooks, are learning tools for pupils that offer various digital support tools and enable pupils to individualize their learning. They may be applied to contexts such as inquiry-based experiments in school laboratories, which involve highly demanding cognitive processes and…
