If you're a regular reader of CanLit for LittleCanadians, you'll know that while I do review some non-fiction books, I do so infrequently. It's not that there aren't great non-fiction books out there–there most definitely are–but I tend to find many dry and text-heavy in their efforts to provide quality content for young readers. While many books are organized well and enhanced with colourful illustrations and typical features of non-fiction texts like maps, glossaries and  info boxes, I find that the content can bog down the book. This is not the case with Susan Hughes and Ellen Rooney's Lights Day and Night: The Science of How Light Works. It's informative but text-light and captivating in its organization and storytelling.

A child and her tuxedo cat enjoy the darkness of a summer evening before witnessing the light that comes from a firefly and the stars. Natural light sources like the sun, volcanoes, lightning and the northern lights are all noted, as is artificial light and the need for some source like electricity or the burning of wood.

Discussions of the uses of light leads to a focus on the sun and energy, the water cycle, absorption, reflection and refraction, and the eyes, all while the girl and her cat enjoy the outdoors, playing and making observations at their cottage on a lake.

Susan Hughes gives young readers the basics about light: where it comes from, what it does and how it works, all within the context of a child playing with her feline companion. Readers will learn important words like translucent and retina and artificial, which are bolded and reinforced in a glossary called "Words to Know." But while learning about light, information which is never cumbersome, kids can enjoy natural landscapes, a cute cat, people in activities supported with light such as walking at a crosswalk or hockey game results on a scoreboard, and know that light is part of their lives too. That same mix of science information and story is blended by BC's Ellen Rooney in her artwork, using cut paper, paint, pencil crayons and a computer to create these collages of light and dark and life.

I know teachers and parents will enjoy using Lights Day and Night as a solid introduction to light and its role in our lives but kids will get more out of the educational messages because of Susan Hughes's text and Ellen Rooney's artwork. After all, an idea is more easily absorbed when presented as in a captivating manner–did I mention the instructions for a shadow puppet show are provided?–and with transparency and brightness.  Lights Day and Night does just that.
