Despite efforts to help youth form better connections to the natural world, many recent science initiatives (such as the "Next Generation Science Standards") privilege laboratory science over field science, thus reinforcing an image of science that is placeless and individual. To better understand the impact of field science on youth, we…

In recent years, scholars have become critical of mainstream leadership development approaches. In particular, Petriglieri and Petriglieri refer to the "dehumanization of leadership," whereby leadership breaks its ties to identity, community, and context. The purpose of this paper is to present an approach for humanizing leadership using…

Apurinic/apyrimidinic (AP or abasic) sites are deoxyribonucleic acid (DNA) lesions that result from the loss of a nucleobase by hydrolysis of the "N"-glycosyl bond. AP sites are the most frequent lesions in cells and are caused by environmental and cancer therapeutic genotoxins. Herein, the bicinchoninic colorimetric assay, typically…

We propose a laboratory experiment on the quantitative study of the normal dispersion of light. A triangular isosceles prism made of flint glass TF3 is used as the object of study, and we describe a simple and affordable device for observing and photographing the dispersion spectrum on a smartphone. A possibility of the quantitative investigation…

The question of how the processes around the Faraday generator with its rotating magnet should be interpreted has been controversial since its discovery by Faraday. Does the magnetic field rotate together with the rotating magnet or does it remain stationary? Furthermore, does one only need Faraday's flux law to interpret inductive processes, or…

For single-slit diffraction and double-slit interference experiments, commercially made slits can be the most expensive parts, especially since the prices of laser pointers have become very low. One option is to use a razor blade to cut slits in either paint or electrical tape on microscope slides. However, this takes practice, and there is some…

In this paper I describe an interactive Gauss's law computer simulation using the GlowScript programming environment. The simulation calculates a point charge's electric field at locations on the surface of a Gaussian cube and displays the electric field in GlowScript's 3D graphics window. The point charge can be moved, and the electric field…

Adults often prefer things that they believe are natural, including natural foods. This preference has serious implications, such as the rejection of cultured meat and other sustainable technologies. Here we explore whether children also prefer natural foods. We conducted two preregistered studies with 374 adults and children from the United…

Determination of enzyme activity is crucial for discovery, research, and development in life sciences. The activity of enzymes is routinely determined using spectrophotometric assays that measure rates of substrate consumption or product formation. Though colorimetric-based detection systems are simple, rapid, and economical to perform, the…

With the availability of educational digital data acquisition systems, it has also become possible in physics education to generate 'big' data sets by (a) measuring multiple variables simultaneously, (b) increasing the sample rate, (c) extending the measurement duration, or (d) choosing a combination among these three options. In the context of…

With the rapid growth of the technology era, the conventional teaching approach is not sufficient for students of the millennial generation. With this in mind, this article presents the justification for incorporating Kolb's experiential learning, based on laboratory practices with an environment supported by simulation software, combined with…

A 2.7 m long stringless pendulum was set up to measure the coefficient of rolling friction of various balls, at higher rolling speeds than usually observed with a short stringless pendulum. The arrangement is easy to set up and makes an impressive classroom demonstration as well as an interesting laboratory experiment.

Though the conversation about race and racism in individual writing centers has developed in the last 30 years (Coenen et al., 2019; Condon, 2007; Dees et al., 2007; Denny, 2010; Faison, 2018; García, 2017; Greenfield, 2019; Greenfield & Rowan, 2011; Grimm, 1999; Kern, 2019; Lockett, 2019), scholars rarely discuss the racial climate of writing…

Writing center scholarship often highlights the ways in which their distinctive, less directive, nongraded, and individualized instruction can make them distinctive social and pedagogical spaces. There is a simultaneous argument, however, that writing centers are often institutionally vulnerable and may be unable to engage in or promote such…

A straightforward experimental set-up, requiring a two-liter bottle, a ruler and a stopwatch, is used to provide data appropriate for modelling with Torricelli's Law in the simplest case, and a more sophisticated differential equation when losses are taken into account and a pipe extension is considered. With only an exit hole included in the…
