WHY IS MILK WHITE?: AND 200 OTHER CURIOUS CHEMISTRY QUESTIONS

Для детей от 9-ти летCovering a wide variety of everyday chemistry concepts from the very simple to the more complex, this question-and-answer primer provides straightforward, easy-to-understand explanations for inquisitive young scientists’ questions. A dozen unique experiments to try at home—from lifting latent fingerprints from a “crime scene” using super glue (for smooth surfaces) or iodine (for paper) to hollowing out the zinc interior of a penny using muriatic acid—are interspersed with the answers to such questions as What makes soda so fizzy? and Why do you get cavities when you eat too much sugar? From separating food coloring into its component dyes to using easy-to-find chemicals to create “slime,” Silly Putty, or bouncing balls, this handy guide is the ideal resource for the budding chemist. When it comes to chemistry, most kids have more questions than answers. Why do you get cavities when you eat too much sugar? How does sun block protect your skin from getting a sunburn? What makes soda so fizzy? And why do you need antifreeze in your car? Teenager Alexa Coelho quizzed her neighbor, chemist Simon Field, with hundreds of perplexing questions, and now she has the answers. Field covers a wide variety of concepts from simple to complex, but always with straightforward, easy-to-understand explanations. And for those readers who want to see chemistry in action, Why Is Milk White? also includes a dozen unique experiments to try at home. Lift latent fingerprints from a “crime scene” using super glue (for a glass or smooth surface) or iodine (for paper). Hollow out the zinc interior of a penny using muriatic acid, leaving only a thin copper shell. Conduct a paper chromatography experiment to separate food coloring into its component dyes. Or use easy-to-find chemicals to create plastic “slime,” Silly Putty, or a bouncing ball. This book is the perfect resource for budding scientists everywhere.
