Introduction to Light: An Illuminating Day! Students were very busy this week exploring the nature of light. They studied reflection, transmission, and absorption of light, the differences between transparent, translucent, and opaque objects, and the spectrum produced by white light. Students then saw colors seem to disappear when viewed through color filters. Ask them how! We recommend: “Light and Color – Hidden Messages” from for an Extension activity after our visit. ( Additional Information: Not all white light is the same! To examine the different light spectra produced by different light sources (incandescent vs. fluorescent bulbs, LEDs, and sunlight) make a spectrometer at home using this link: Two notes: 1) For safety, use folded aluminum foil instead of razor blades for the slit; 2) It’s helpful to score the CD with a blade (a job for parents) before breaking it, and to cover it with a towel while you snap it, to keep pieces from scattering. Once broken, the CD pieces are easy to trim with a scissors.

Introducción a la luz: un día “iluminado” Los estudiantes estuvieron muy ocupados esta semana explorando la naturaleza de la luz. Estudiaron la reflexión, la transmisión y la absorción de la luz, las diferencias entre los objetos transparentes, translúcidos y opacos, y el espectro producido por la luz blanca. Los estudiantes luego vieron que los colores parecen desaparecer cuando se ven a través de filtros de color. ¡Pregúntales cómo! Información adicional: Para examinar los diferentes espectros de luz producidos por distintas fuentes de luz (incandescente vs fluorescente vs LED y luz solar), haga un espectrómetro en su casa siguiendo las indicaciones que aparecen en este link: Notas: 1) Por seguridad use papel de aluminio en vez de cuchillas de afeitar para la rendija, 2) es útil marcar el CD con una cuchilla (tarea para los padres) antes de romperlo, además de cubrirlo con una toalla mientras lo rompe para evitar que las piezas se dispersen. Una vez roto, las piezas son fáciles de recortar con una tijera.
