From award-winning author Tanya Lloyd Kyi, an eye-opening look at the science of sleep --- covering everything adolescents could possibly want to know about a subject that's suddenly keeping them up at night! For something that all humans do for hours every night, sleep is not that well understood. One thing we do know, though, is that sleep is crucial for our health and happiness. Here's a highly readable and fascinating look at why sleep is so important, what's happening in our bodies while we're sleeping (it's a lot more than you think!), and how the science of sleep research has evolved. It probes some of the mysteries about sleep, like why we need sleep, why we dream, and even how long we can go without sleep! It also explains why teens and tweens aren't getting enough sleep --- and what school principals can do about it! It's a deep dive into an intriguing topic that's anything but a snore! Bestselling author Tanya Lloyd Kyi's engaging yet comprehensive text covers everything a middle schooler (or an adult!) could want to know about the science of sleep --- and then some. Sleep is a topic that most adolescents are interested in, since their sleep patterns have recently begun to change, and getting enough sleep is now more important to them than ever before. Sidebars and boxes full of fun facts break the text into readable chunks. There are terrific curriculum links here to life science and the human body as well as to health. Fully illustrated with a light touch by Valéry Goulet, this unique and appealing book makes scientific content accessible and fun.
