"Water molecules are amazing--and so is just plain water! In this book, young scientists investigate how water droplets can magnify, the magic of surface tension, and the effects of adding salt to water when potatoes are in it! Each of the ten projects . . . explain[s] the science topic at work, materials, clear step-by-step instructions, and an observations section helping young scientists understand what they've done. Several projects include science fair ideas and expanded versions of the experiment to engage readers further. [Includes a] discussion of the scientific method"--Provided by publisher.

"Meet Cloud! Follow along as she moves, transforms, precipitates, and more in this ... humorous portrayal of the water cycle"--Amazon.

Looks at how water helps the Earth's global balance, discussing the water cycle, bodies of water, precipitation and more.

"Looks at the scientists who summited volcanic peaks to peer through an atmosphere's worth of water vapor, cored mile-thick ice sheets to uncovr the Earth's ancient climate history, and flew inside storm clouds to understand how small changes in energy can produce both massive storms and the general circulation of the Earth's atmosphere"--Adapted from publisher description.

Introduces readers to the skills, tasks, and expectations of pursuing a career as a hydrologist.

Readers will come to understand how the water cycle tracks water's movement from one phase to the next.

Large bodies of water are all around us: rivers flow through our towns and cities, inland lakes collect pools of fresh water, and the salty ocean covers nearly two-thirds of the Earth's surface. In this volume, readers will learn about the importance of these three natural sources of water, as well as their similarities and differences.
