Sometimes it is because my glasses are dirty. Sometimes it is a sundog, or a light pillar, or, if I happen to be near an exploding volcano….
Nature’s Light Spectacular: 12 stunning scenes of Earth’s greatest shows, written by Katy Flint and illustrated by Cornelia Li is a top notch earth and science book across a very wide age range, but classed as a 4-8 year old book. This book sits across that divide of read to vs. read by, and I think it is a great read-by (the kid) book for up to 10 or 11 years old.*
There is a story that pulls it all together, about two young explorers who improbably encounter several different light phenomena in nature, some common like sun dogs, some much less common, like the waterfall of fire at Yosemite National Park. Each two page layout demonstrates the phenomenon, with additional graphics and well written text to explain the science behind it. The format is large and guess what: The book glows in the dark.
Good science, good teaching, good book. The glowing in the dark part is not the reason you want this book, but you do want this book if you have a kid in elementary school.
