Direct linkDai, Rucheng; Wang, Zhongping; Zhang, Zengming; Sun, Lazhen – Physics Teacher, 2022
In this paper, an experimental setup composed of a color-mixing device, power supply, and spectrometer is developed. This setup is available for students to do hands-on color mixing with red, green, and blue light in undergraduate labs. LED volt-ampere and spectrum characteristics are investigated. The apparatus was used to perform additive color…

DeVita, Christina; Ruppert, Sarah – Science and Children, 2007
Light is radiation in wavelengths composed of many colors that are visible to the eyes. These wavelengths can be separated. One way to separate colors is with a filter. Filters keep certain wavelengths out and allow other wavelengths to pass through. In this article, the authors discuss an activity to provide students the opportunity to build a…

Akcay, Hakan – Science Activities: Classroom Projects and Curriculum Ideas, 2005
The main goals of these activities are to help students learn how a convex lens can serve as a magnifying lens and how light travels and creates images. These explorations will introduce middle school students to different types of lenses and how they work. Students will observe and describe how lenses bend light that passes through them and how…

Peer reviewedJewett, John W., Jr. – Physics Teacher, 1993
Describes the nineteenth-century parlor trick entitled the Fluttering Heart phenomenon which uses a red heart on a bright blue background. Discusses theories concerning the apparent fluttering. Suggests doing the trick with a red light-emitting diode in a darkened room. (MVL)

Peer reviewedHarris, John – School Science Review, 1999
Presents scientific explanations of primary colors and color mixing, black and white surfaces, the spectrum and the ability of the eye to distinguish color difference, the description of color, and the appearance and optical properties of metals. Contains 16 references. (Author)

Peer reviewedMayshark, Robin K. – Science Scope, 1991
Students explore three-dimensional properties by creating red and green wall decorations related to Christmas. Students examine why images seem to vibrate when red and green pieces are small and close together. Instructions to conduct the activity and construct 3-D glasses are given. (MDH)
