DNA-functionalized gold nanoparticles (DNA-AuNPs) have become a popular science theme since their invention in 1990s. They impact our daily lives by playing key roles in rapidly identifying and quantifying important analytes, and are a well-suited chemistry course content for beginners of chemical research. While the salt-aging method represents…

The helium-plasma (HePI) ionization mass spectrometry method was used to track the formation of reaction products and consumption of reactants by continually monitoring the vapors in the reaction headspace in real time. Two examples of the application procedure are presented here: a nucleophilic acyl substitution reaction and a 1,4-nucleophilic…

The discovery of ferrocene, Fe(C[subscript 5]H[subscript 5])[subscript 2], in the 1950s sparked the development of organometallic chemistry including metallocene compounds. Shortly after the isolation of ferrocene, the analogous ruthenium and osmium compounds were discovered. The preparation of ferrocene is common in undergraduate inorganic…

Project-based learning is widely used in organic laboratories. This goal-oriented and inquiry-based learning model complements student-centered training. Such models focus on complicated issues or real-world problems on the frontier of chemistry. Students progress through three project phases: preproject, during the project, and postproject.…

The worldwide scientific community has been promoting science communication from colleges and universities to schools, and different tools for communicating scientific discoveries have been created. Among this variety of tools, our choice fell on a storybook. The book, entitled "The Curious Case of Ants That Live in Galls," is directed…

While scientists place high value on the scientific method, its relevance to everyday life is often opaque to nonscientists. In undergraduate teaching, its implementation is primarily apportioned to upper-level, laboratory science classes for majors. Herein we describe the modification of a recipe as a real-world project for learning the…

The Clemmensen reduction is a common example of a reaction demonstrating the deoxygenation of carbonyl groups, which is a topic that has been widely studied in the field of organic chemistry. The use of trimethylchlorosilane, as a substitute for concentrated hydrochloric acid, allows for the reduction of carbonyl groups. The Clemmensen reduction…

Magicians and scientists have a curious relationship, with both conflicting views and common ground. Magicians use natural means to construct supernatural illusions. They exploit surprise and misdirected focus in their tricks. Scientists like to deconstruct and explain marvels. They methodically measure, evaluate and repeat observations. However,…

An interdisciplinary approach to science education through history of art is proposed. The approach is innovative, as the artworks complement the history, philosophy and sociology of science contents to increase students' interest and motivation. The approach integrates humanities and science education through history of art, which requests…

Chemical engineering is a challenging field to explain to first-year students. Food production processes are a safe and accessible way to introduce the students to basic engineering concepts. Modernist cuisine -- using scientific methods and engineering techniques to enhance classical cooking -- was used as a hook to capture the attention of…

With a growing number of global challenges related to the environment, water, public health, and energy, there is an imminent need to teach chemistry in the context of its interconnectedness with other systems. Project- and problem-based learning are student-centered learning approaches which offer educators the opportunity to engage learners in…

Having written columns dealing with science fairs before, Bill Robertson notes that it's been a long time since he has tackled the subject of what passes for a "science fair" in schools these days. Because science fairs have changed over the years, Robertson revisits the topic and explains the scientific method. The main focus of the…

Although the Stanford Prison Experiment (SPE) has been challenged on methodological, theoretical, and ethical grounds, these criticisms have been largely ignored by teachers and textbook authors. Recent revelations arising from an analysis of the SPE archival materials, however, not only strongly support these past criticisms but also question the…

The concept of reactance in AC electrical circuits is often non-intuitive and difficult for students to grasp. In order to address this lack of conceptual understanding, classroom exercises compare the predicted resistance of a power tool, based on electrical specifications, to measured resistance. Once students discover that measured resistance…

One of the most perplexing dilemmas in modern science is chronic fatigue syndrome (CFS). Even though the illness was recognized at the beginning of the 20th century, the pathogenicity and etiology of the disease remain unknown. We describe an open-inquiry case study on CFS that we have used in our biology classrooms to increase students'…
