Project-based learning is one of the most effective and successful teaching methods for STEM topics. Project-based teaching is an open-ended teaching method that helps teachers stimulate students' initiative and teamwork skills and promote creativity. Of the interdisciplinary STEM topics, teaching students how to produce aromatic wax proved an…

This study sought to evaluate an English language acquisition program at a public, urban high school in Connecticut. To that end, qualitative and quantitative data was compiled and analyzed. Qualitative data was mined to determine teacher perceptions about the program and levels of supports and interventions provided to those students identified…

Martin Wagenschein's ideas of prioritising phenomena in making sense of science processes have influenced the German "Lehrkunstdidaktik" (art of teaching) approach. This article sketches a "Lehrkunstdidaktik" teaching unit inspired by Michael Faraday's "Chemical History of a Candle." It shows how primary and lower…

As the application of colored designs on cloth using wax in certain areas in decorating items of clothing, Batik is made through several steps that come from drawing the pattern on the paper followed by imitating the pattern on fabric, which is called "ngeblat." The next phase is followed by drawing the pattern using wax, which is called…

Plastic waste and the bee population are two topics often discussed in relation to the environment. A practical activity in a primary school classroom linked to these areas can help to fulfil some of the requirements of the science curriculum. A study of the life of bees shows the importance of pollinators and highlights the concern many people…

Wax, taffy, immigration. Removal, alien, roots, belonging. Screendance. These apparently unrelated words were the inspiration for "Uprooted," a screendance project that addresses issues of immigration through movement and metaphor. Developed with a cast and crew of college students, "Uprooted" became the nucleus for community…

We describe a paper-based microfluidic device for iron(III) assay in an applied instrumental analysis laboratory. Simple and convenient devices were fabricated by the students using patterning of filter paper to investigate three different procedures: drawing a boundary with eyeliner or wax pen; drawing a boundary with waterproof permanent marker…

In the United States, there is a widespread concern with not referring more infants and toddlers with a risk of or identified autism spectrum disorder (ASD) to Early Intervention (EI) under Part C of the Individuals with Disabilities Education Act (IDEA, 2004). Despite early signs and screening initiatives, most children with ASD are not referred…

An easily constructed and inexpensive polarimeter with an optical rotation angle resolution of about 0.5° is presented. It is made from small pieces of polarizing film, 2 LEDs, a protractor, and a few wires, all held in place with plastic interlocking toy bricks, such as Lego bricks. The instrument was used to demonstrate the optical rotation of…

In this article we are analyzing which spherical symmetry groups can be found and which ones cannot among the eggs with wax-resist patterns most frequently used in the Carpathian Basin. We are also trying to answer the question why exactly these symmetry decorations can be found. Before that, we are providing a review on the history of decorating…

An undergraduate organic chemistry laboratory experiment involving the breakage of amide C-N bonds is reported. Whereas amides are typically considered stable species due to well-established resonance effects, this experiment allows students to cleave the amide C-N bond in a nickel-catalyzed esterification process. Moreover, students perform the…

Surface anatomy is an important skill for students in preparation for patient care, and peer examination is often used to teach musculoskeletal and surface anatomy. An alternative pedagogical approach is to use bodies represented in artworks. Represented bodies display fictive anatomy, providing students with the opportunity to apply their…

DeLand Crayon Company (DCC) is a large manufacturer of molded wax crayons. DCC sells three sizes of crayons, namely standard, large and jumbo. Standard-sized crayons, which account for most of the demand, include nine basic colors (red, blue, green, yellow, orange, violet, brown, black, and white), seven popular combination colors (red-orange,…

In this article, a low-cost, simple, and rapid fabrication of paper-based analytical devices (PADs) using a wax screen-printing method is reported here. The acid-base reaction is implemented in the simple PADs to demonstrate to students the chemistry concept of a limiting reagent. When a fixed concentration of base reacts with a gradually…

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…
