Inquiring minds in primary grades can gain understanding about a seemingly ever-present subject in this title about light in the Let’s-Read-and-Find-Out Science series.
Pfeffer begins her straightforward text by discussing sources of light from the sun and stars, as well as those powered by electricity. Soon readers are discovering how light travels to Earth from the sun 93 million miles away. The challenging concept of how fast light travels is made clear by Meisel’s appealing spreads comparing the speeds of various vehicles (car, plane, etc.) to light. The notion of measuring a particular light’s brightness in lumens unfolds alongside a series of spot illustrations showing how length, time, temperature and weight are measured. Bioluminescent creatures, such as common fireflies and the more exotic glowing octopus, get a quick mention before an accessible and informative explanation of how the eye works is impressively executed by both author and illustrator. Simple experiments proving how necessary light is to living things and suggested activities about shadows are provided at the title’s conclusion. A note states that this book “meets the Common Core State Standards for Science and Technical Subjects.” Newly independent readers will appreciate how closely the pictures reflect and extend the text, while younger students will gain much from listening to the book read aloud and poring over the details on each page.
An illuminating choice for the science shelf. (notes on experiments) (Informational picture book. 5-8)
