Time For Kids recently sent me a children book to review on my dad blog. The book is titled, BIG Book of Why: 1,001 Facts Kids Want to Know. As you can tell from the title, it’s full of fun facts and answers to questions kids might ask. Each answer includes a photo or an illustration to explain the why behind each question. The reading level of the 192-page book is ages 9-12. I had my ten-year old daughter read the book and she said she enjoyed it. I think many dads and moms will find the book interesting too. The hardcover book is currently selling for $13.57 at Amazon (list price: $19.95).
Here are some answers I found interesting:
Why do vampire bats drink blood?
Obviously, vampire bats are not related to vampires. Scientists think vampire bats evolved from bats that gorged themselves on the parasites of prehistoric beasts. Did you know vampire bats are the only mammals that feed entirely on blood? [Note: vampire humanoids are not considered mammals because vampires are just dead things that make movies.]
Why do some bugs glow in the dark?
Bugs that glow in the dark are bioluminescent. Chemicals in their bodies combine to make them glow. The bugs light up to communicate with each other when they are looking for a mate. This is exactly how I attracted my wife.
Why do camels have humps?
Camels store fatty tissue in their humps. In the dry desert, camels’ fatty humps let them live for a long time without water. OK, this explains what the humps are used for but it doesn’t explain why the fat is stored in the humps instead of elsewhere. Could you imagine a world where humans store fat in humps on their back instead of in the belly or butt?
Why isn’t the sky black, purple, or green?
Light from the sun is made up of different rainbow colors. When light passes through our atmosphere, nitrogen and oxygen atoms break up the light. These atoms break up the color blue much more easily than other colors and that is why our sky is blue instead of black, purple, or green. Oregon must not have nitrogen and oxygen atoms because we see gray skies ten months out of the year.
Why do stars twinkle?
Stars don’t actually twinkle. They appear to twinkle because the moving air bends the light of stars as it travels through the atmosphere. Each time you look at a star, the path of its light has changed slightly, which gives the illusion that the star is twinkling. Hmmm. I wonder if this explanation will work the next time my wife sees someone winking at me (it happens all the time). Honey, she didn’t wink at me. It’s just an illusion caused by the wind.
Why are there holes in Swiss cheese?
Cheese is made by adding bacteria to milk. Three types of bacteria are used to make Swiss cheese. One type of bacteria gives off bubbles of carbon dioxide and these bubbles create the holes in Swiss cheese. I think this is the same bacteria responsible for airheads.
