What's the Big Idea?: Amazing Science Questions for the Curious Kid

Thirty-five important science questions and answers that help kids learn about motion, energy, matter, and life, fully illustrated in vibrant color.Why does a rolling ball stop rolling? Why doesn’t the sun burn out? Why can’t you unscramble an egg? Why can’t we live forever? These are all questions that a curious kid might ask. In What’s the BIG Idea?, renowned juvenile science educator Vicki Cobb answers these and thirty-one other fascinating questions to help kids learn more about the world through the wonders of science. A big idea is one that has no simple or easy answer, and there are four big ideas in this book: motion, energy, matter, and life. The motion of nonliving objects—rolling balls, falling stones, the moon and stars—seems so ordinary and familiar that most people take it for granted.
