Why don''t we feel the Earth move? Why does an ice cube float? 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 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. Matter, on the other hand, comes in so many different forms—solids, liquids, gases, metals, nonmetals, living material—that it is hard to imagine anything that all matter has in common. Energy is an idea that is in the news just about every day, yet most people couldn''t tell you what the big idea of energy is. And life—what life is—seems mind-boggling and infinitely complicated. How do we bend our brains around it?Scientists learn by asking questions. And this book, now in paperback, is designed to make young readers stop and think about each of the questions before reading what scientists have learned that answers each question. They''ll be able to do simple things to see for themselves, and they will build their own scientific knowledge in the process. By the time they''ve finished this book, they''ll get the big picture of what science is all about.

Would you believe that you could throw an egg across the room without breaking it? Burn a candle underwater? We Dare You! is a gigantic collection of irresistible, easy-to-perform science experiments, tricks, bets, and games kids can do at home with everyday household objects. Thanks to the principles of gravity, mechanics, fluids, logic, geometry, energy, and perception, kids will find countless hours of fun with the selections included in this book.

With See For Yourself, budding scientists can wow their teachers and classmates (and maybe win a ribbon or two) by learning How to extract DNA from an onion How pigments from vegetables make dye How to make paper out of lint from a clothes dryer How to make a friend feel like he or she has a third hand What happens when you grow yeast in dandruff shampoo That tea and iron pills make excellent inks And much more! See for Yourself includes experiments in the areas of chemistry, earth science, physical science, the human body, and technology, but the experiments all take their inspiration from very familiar places. The materials needed to execute the experiments can all be inexpensively purchased at the supermarket, the toy store, the hardware store, the stationery store, and the drugstore. Some of the experiments are quick and easy, while others are more challenging. Most include additional suggestions so that curious young scientists can keep on investigating.
