Iron metabolism is an important subject of study for undergraduate students of chemistry and biochemistry. Relevant laboratory exercises are scarce in the literature but would be very helpful in assisting students grasp key concepts. The experiment described here deals with different iron release mechanisms of two protagonists in iron metabolism:…

In this article, the authors reflect on Myrna's Children's Village, their university laboratory school located in southern New Mexico in the USA. The Village serves children from the age of six weeks to five years through an array of early childhood programs. This diversity provides a unique context, while also posing issues and concerns, such as…

The Advancing Science and Engineering through Laboratory Learning (ASELL) for Schools program has been instrumental in getting schools across Australia to reconsider the effectiveness of the laboratory learning activity (LLA) in science education. In Victoria, the ASELL for Schools project has collaborated with another nationally funded program,…

Historically, students from racially minoritized communities receive exclusionary disciplinary actions more frequently and severely in the United States. Researchers have recommended that schoolwide behavioral interventions implemented to address racial disproportionality need to be culturally responsive to local school contexts. Using the theory…

Reported herein is a multidisciplinary experiment for senior-level undergraduate teaching laboratories in the synthesis of the analytes acetaminophen and phenacetin; the fabrication of paper-based devices, using eyeliner, acrylic spray paint, or wax-printing, for sensing of those analytes; and the use of the newly fabricated devices for successful…

Most didactic lab experiments deal with the influence of temperature, concentration, pressure, surface area, and catalysts on chemical kinetics; however, few of them explore the influence of light radiation and the presence of inhibitor agents on reaction rates. In order to investigate the effects of the radiation source and the presence of…

A versatile experiment is described for the high school and college laboratory setting based on the synthesis of biobased polymers prepared from inexpensive, renewable, and nonhazardous chemicals. Combinations of readily available citric acid, glycerol, and tapioca root starch are used to prepare three polymeric materials with different observable…

A multiweek laboratory experiment is described, which guides students to use data to make decisions through multiple steps, before reaching a final conclusion. The lab focuses on the comparisons of fluorescence and absorbance spectroscopies to determine the concentration of a desired substance in an unknown sample in consideration of a complex…

Over the past several decades, green chemistry has gained prominence in chemistry education. However, the development of green chemistry curricula has not reached all levels of education equally, focusing mainly on elective and upper division courses. We deliberately focused our green chemistry curriculum redesign on a high enrollment introductory…

Purpose: In the 21st century, the importance of the fields of science, mathematics, technology, and engineering, and the need of the skilled individuals have paved a way for a great responsibility on teachers providing instruction in these four fields. Therefore, in this context, it is essential that teachers need to receive education for the…

This paper examines the diverse activity of the International Network Center for Fundamental and Applied Research (INCFAR) in conjunction with the institution's fifth anniversary. The authors describe the process of creation and reorganization of the INCFAR Laboratories and discuss the Center's cooperation with other research-and-education…

A new undergraduate inorganic chemistry laboratory experiment is presented. An introduction of the spectrochemical series and ligand exchange is explored using the coordination complex dirhodium tetraacetate, Rh[subscript 2](OAc)[subscript 4]. Students have measured the absorption spectra of the Rh[subscript 2] complex in the presence of various…

A creative apparatus for use in a hands-on laboratory experiment that allows the visualization of the vapor pressure as a function of temperature is described in this paper. Inspired by homemade barometers and using simple materials that are easily accessible for teaching laboratories, a lowcost system for the establishment of the vapor-pressure…

The ACS Guidelines for bachelor's degrees in chemistry call for the curriculum to include polymer chemistry principles and the synthesis of different classes of macromolecules. Organic chemistry can provide an important introduction to polymer chemistry principles, and photochemically induced radical polymerization is one method for generating…

A couple of experiments analyzing the vibration of bars in different configurations using as a vibration sensor an electric guitar pickup are presented. The device is a versatile and easy to operate sensor that can be used in experiments involving the analysis of vibrations in rods and bars of different composition and in different configurations.…
