A Ray of Light

Gr 2–7—Large eye-catching photos are the star of the show in this exploration of light. In addition to examining basic topics such as light waves, the sun, color spectrum, reflection, and refraction, Wick also tackles iridescence, pigments, and other concepts not often covered in introductory books for children. Photos illustrate how lenses work in a camera, telescope, and magnifying glass, and show a prism refracting light or close-up views of iridescent insects and feathers. Much of the text serves as expanded captions for the photos. Some smaller images are harder to see, such as the tiny beam of light split into colors after passing through a water-filled box. The text refers to the processes and experiments behind the photos, and Wick provides more extensive instructions and explanations in two pages following the main text. Although upper elementary students may be able to do some activities with adult help or supervision, younger students will probably remain observers of teacher or parent demonstrations. Without a glossary, index, or list of additional sources, Wick's title may serve best as a starting point to encourage explorations using hands-on activities found elsewhere.
