Two different methods of measuring the temperature of an incandescent lamp at various voltage levels are described. By observing the color produced at a particular voltage levels, the lamp's color as a function of temperature can be determined. Needed equipment include a variac, a voltmeter, and an ammeter. (KR)

Discusses Biblical narratives for children and suggests criteria to use for assessing Bible story books. Twelve examples of good books are described, including picture books as well as stories for older children. Features that are discussed include illustrations, use of color, readability, and racial assumptions. (LRW)

A longitudinal study examined the role of a mapping system in 2-year olds' learning of color and size words. Results indicated that the children acquired color maps in a characteristic order and showed a different acquisition pattern for size words. Results suggest that learning word associations may promote color-word acquisition; learning color…

Describes two related color-change reactions that are relatively easy and safe to demonstrate. In the "Sunday School Reaction", a black and a white solution are mixed to form a white solution. In the "South Africa Reaction", a series of black, brown, red, and white solutions are mixed to form a clear, colorless solution. (WRM)

Contends that the principles of unity, variety, and balance can be taught to elementary school students through the production of relief sculptures. Describes how students were introduced to relief sculpture and how they created sculptures using common materials. Relates how painting the sculptures was related to a lesson on color. (DSK)

Presents an art assignment that helps students progress from color theory and the color wheel to understanding watercolor techniques. Explains that students apply their knowledge of watercolor techniques by using three of ten techniques to create different views of a chair in the Cubist style. (CMK)

Three studies, involving 72 3-month-old infants, demonstrated that infants remembered some of the original feature combinations of a mobile they had been trained to activate for up to 3 days but forgot all of them after 4 days. Even after 4 days, however, infants remembered the individual features that had entered into the original combinations.…

Presents an art lesson for elementary students using painter Claude Monet as an introduction to Impressionism. Discusses Monet and his artwork. Explains that the students copy Monet's painting "The House of Parliament, Sunset" in order to draw the contour or outline of the buildings. (CMK)

Describes an exercise in which students can use flashlights, mirrors, and colored paper to discover scientific principles regarding optics. Addresses the concepts of angles of incidence and reflection, colored vs. white light, and mirror images. (WRM)

This paper reports two experiments that investigated the role of verbal behavior in the emergence and generalization of contextually controlled equivalence classes. During both experiments, participants were trained with two different combinations of the same easily nameable, yet formally unrelated, pictorial stimuli. Match-to-sample baselines for…

In studies of function transformation, participants initially are taught to match stimuli in the presence of a contextual cue, X; the stimuli to be matched bear some formal relation to each other, for example, a relation of opposition or difference. In a second phase, the participants are taught to match arbitrary stimuli (say, A and B) in the…

Genetics is often a fascinating but difficult subject for middle level students. They can see the results of genes in every organism, but trying to visualize what happens at the level of genes is challenging for concrete thinkers. The author discusses an approach that helps students understand how genotypes can translate into phenotypes, then…

The procedure to produce standard curve for starch concentration measurement by image analysis using a color scanner and computer for data acquisition and color analysis is described. Color analysis is performed by a Visual Basic program that measures red, green, and blue (RGB) color intensities for pixels within the scanner image.

This eight-year study represents a pioneering effort to investigate color expression in children's graphic notations at two stages of development: "Pre-literate" (age: 7.0-8.5), before students received school music instruction, and "Post-literate" (age: 14.0-15.5), three years after students acquired Standard Notation in…

Selections of liquid aldehydes and ketones are proposed for students to determine what property is the best predictor of the color (yellow to red) of their 2,4-dinitrophenylhydrazone derivative. Students may use a computer (spreadsheet or word processor) to analyze results. (Contains 1 table and 3 notes.)
