Working with cognitive literary theory, affect theory, semiotics, and recent picturebook scholarship, this essay looks at the ways the concept book (as a subtype of the picturebook format) connects color to emotion. In doing so, it suggests that one of Western culture's most commonly accepted ideas of color and color meaning may contribute to…

Using polymerizable cholesteric liquid crystal (CLC) paints, we prepare circularly polarized freestanding films that enable students to acquire a basic understanding of circular polarization and molecular chirality. The polymerized helical structures of CLC films can exhibit brilliant structural colors by selective reflection of visible light…

Courses: Gender roles and communication, interpersonal communication, communication theory. Objectives: This activity introduces students to the social construction of gender, and asks them to consider gender diversity by understanding that shades of pink and blue exist within the binary. Specifically, students are given blue or pink color…

A simple photometric device was built to measure the kinetics of the title reaction. The device consisted of a green light-emitting diode (centered at 520 nm), a sample vial, a photodiode, and an Arduino microcontroller board. These parts were mounted on a black poly(lactic acid) holder which was manufactured by utilizing three-dimensional…

Undergraduate-level laboratory experiments that integrate multidisciplinary chemistry concepts into a single activity are very appealing and thought-provoking for chemistry students. Here, we use the oscillating chemical reaction to introduce students to the analytical detection concept. The Belousov-Zhabotinsky reaction is employed as a simple…

Children's literature scholars have written about the importance of color in the visual texts of picturebooks: Color can establish mood, provide clues to the emotional states of characters, highlight particular objects in illustrations, and signal links between characters and/or objects (e.g., Lewis, 2001; Moebius, 1986; Nodelman, 1988). However,…

One of the world's most famous pyramids is not located in Egypt but is on a music album cover by the band Pink Floyd. However, not a pyramid but a prism, the iconic image of a beam of light turning into a rainbow is a powerful symbol that captures the complexities of colour perception across cultures and individuals. This study examines how…

The essence of university courses lies in their scientific rigor, while the enjoyment of learning serves as a motivation. In this regard, we have developed a comprehensive experiment project by incorporating dithienylethene-based photochromic units into sensitizers for renewable energy, specifically dye-sensitized solar cells, through organic…

Red onion, "Allium cepa," juice can dye a cloth sample green upon the addition of alum, aluminum potassium sulfate, and this sample can turn red when subjected to an acidic solution. When the red-colored sample is washed with a neutral or alkaline aqueous solution, its color turns green again. These experiments illustrate color changes…

Children on the autism spectrum often have deficits in language development. Given the resources required to provide intensive intervention services, either in person or via telehealth, it may be important to maximize instructional time by using procedures that lead to generative language use, such as matrix training. Matrix training involves…

This is an easy and inexpensive laboratory experiment in which undergraduate students at the Bachelor's degree level in Chemistry can measure formation constants of complexes [Ni(en)[subscript n](OH[subscript 2])[subscript 6-2n]][superscript 2]+ (n = 1, 2 or 3; en = ethylenediamine) through an acid-base titration. The background information…

The distinction between "Big-C" and "little-c" creativity implies that the generative process of celebrated creators is of a special type or degree. Arguments for and against such a hierarchy of creativity are found in the literature, primarily built on rhetorical argumentation. The aim of this work is to examine the rationale…

Raman scattering is a powerful tool for revealing the vibrations of molecules, but as a nonlinear optical phenomenon, its signals can change via mechanisms like resonance enhancement that have no direct analogue in infrared spectroscopy. In this work, complementary measurements conducted on 4-nitrophenol and its conjugate base allow students to…

This study investigates the influence of plant landscape colors on the quality of life of college students at Sichuan Vocational College of Health and Rehabilitation in Zigong City, China. The research employed a mixed-methods approach, integrating quantitative data from 328 student questionnaires with qualitative insights from in-depth interviews…

In this study, we describe a method to employ a conventional compound light microscope, usually available in laboratories, to obtain fluorescence. In particular, two pieces of colored acrylic plastic were utilized to assist the microscope in filter performance. We also attempted to examine the applicability of the setup by staining onion cells…
