Anaerobic respiration reactions are of fundamental importance to global biogeochemical cycling of elements. Yet, the idea that cellular respiration can occur not only in the absence of oxygen but also involve the oxidation of inorganic substrates (e.g., AsO[subscript 3 superscript 3-], Fe[superscript 2+], H[subscript 2], H[subscript 2]S,…

A new approach, termed the "scale factor method," is presented for solving a variety of stoichiometry problems. Students taught to solve mass-mass stoichiometry problems using this method found it more intuitive and had a higher rate of success than students using the traditional dimension analysis approach. The scale factor approach…

Herein, we present a program implemented in Python that utilizes a simple complete-search algorithm to determine the geometry of a lanthanide-substrate (LS) complex. The program serves as a practical project in a programming course for chemistry students, specifically aimed at illustrating fundamental concepts such as decision-making, repetition,…

The article presents a 5E environmental science lesson to help students understand the major environmental factors that lead to acid rain. Students are supported to ask scientific questions to solve the mystery of how acid rain might impact historical buildings. This lesson can be used in a variety of settings both in person and online modalities.…

For most students, completing practice problems is an essential prerequisite for success in organic chemistry courses. Practice work, however, is sometimes perceived to be easier than or even not related to the types of chemistry that students see in assessments and "real-world" science. This negative view may contribute to a reduced…

In this article, we present a hierarchical model for teaching scientific thinking to gifted students. This article follows up on an article published 40 years ago in this journal. The problem now, as 40 years ago, is that gifted students often are taught science courses at a more intensive level, but without their truly learning how to think…

Connections among the mathematics, science, and engineering disciplines have been recognized and affirmed in national standards. For example, the application of mathematical ideas and skills within science has been highlighted in national science standards for over 20 years. More recently, the Next Generation Science Standards (NGSS; NGSS Lead…

Nuclear magnetic resonance (NMR) spectroscopy is a very powerful analytical method that has found many applications in physics, chemistry, biology, and medicine. It is an indispensable tool particularly for synthetic chemists because it can be used for a rapid elucidation of the structures of organic compounds. For this reason, NMR spectral…

The COVID-19 pandemic has been one of the greatest challenges faced for a very long time. However, it has also presented educators with novel opportunities for teaching, none more so than in science. There are the obvious links between COVID-19 and the body of scientific knowledge that curriculum designers think educators should help students to…

The public's growing interest in epigenetics, particularly its applications in human health, underscores the significance of epigenetic mechanisms in regulating gene activity and promoting phenotypic diversity without altering DNA sequences. Within the framework of the Extended Evolutionary Synthesis, epigenetics is regarded as a non-genetic…

A problem-based learning activity focusing on the human impact on the environment and the importance of sustainable development is presented. The activity revolves around a mysterious island where the civilization is on the blink of extinction, prompting students to investigate how human behavior, ecosystems, resources, and natural balance…

Access to drinking water is becoming more limited as drought persists across continents. This article highlights a particularly impacted group of students due to increasing drought conditions and upstream river pollution near their reservation. While there are related water and modeling standards across the K-12 Next Generation Science Standards…

While biomedical and life science research have embraced interdisciplinarity as the means to solving pressing 21st century complex challenges, interdisciplinarity in undergraduate education has been more difficult to implement. As a consequence, disciplinary rather than interdisciplinary capstones have become ubiquitous. Disciplinary capstones are…

This paper highlights the design process and implementation for an "all majors" undergraduate course that allows students a chance to reconnect with the natural world. During this course students explore a wide range of biological and physical science based topics that seek to highlight human intervention and our impacts on the planet.…

Students enter classrooms equipped with a rich foundation of skills and knowledge from their everyday experiences. High-quality science education builds on students' wealth of experience in making sense of the world. In science classrooms, "sensemaking" is a collaborative practice that includes students sharing initial ideas with peers…
