Gr. 5-9. Why is the sky blue? What color is water? Do parrots understand what they say? These are but a few of the questions, common and not so common, answered in a compilation drawn from Wollard's syndicated newspaper science column. Organized in a roughly topical fashion and crisscrossing the science spectrum from physics to astronomy to biology, the questions are answered, not only in considerable detail (each column was originally around 500 words) and understandable terms, but also with a concerted effort to keep the science light and related to young people's everyday experiences. Debra Solomon's zany black-and-white cartoon drawings are strictly for laughs. Browsers as well as the seriously science-minded will find much to intrigue them. Stephanie Zvirin

NOW YOU CAN KNOW IT ALL
Firefly light and the aurora borealis. Time travel and tears. Blood types, boomerangs, and black widow spiders. Explanations and investigations. A fact-filled, fun-filled, whimsically illustrated compendium, HOW COME? answers over 100 of the questions asked most frequently about the world around us.
It explains what a mirage is (an image caused by air bending light). How a cat can survive a high fall (because of the way its body acts like a parachute). And why, when someone else yawns, you want to yawn too (in primitive times, yawns may have been a way to synchronize group behavior).
So go ahead, ask it your best question.
Can you say why the sky is blue? Or explain how an X-Ray can take a picture of your child's bones? It's not easy to be knowledgeable in all walks of science, but here's lively help for when the questions start coming.
