These titles provide brief yet clear information on their respective topics. Day Light discusses the nature of light, darkness, and seeing, and the role heat plays in generating light. Floating in Space discusses how astronauts move and cope with weightlessness in space. Amusing illustrations, verbal and pictorial, demonstrate how gravity works. Children will find much of the information both entertaining and interesting, such as the way astronauts eat with magnetized trays that hold utensils in place. Full-color paintings illustrate the first title and softly colored cartoons enhance the latter. Both are worthy additions to collections that need science materials for early grades.

In this Let's-Read-and-Find-Out Science entry, Branley (see review, above) takes readers on a space shuttle mission, from blast-off to touchdown, but focusing mainly on life in orbit. As he points out, ``zero gravity'' is a misnomer--but only barely; so negligible is gravitational pull that astronauts temporarily grow an inch or so as their joints relax, are able to stand on the walls and ceiling, have to learn new ways to eat, sleep, and use the toilet, and must be very careful about stowing small objects before re-entry. In Kelley's cheerful watercolors, smiling space travelers--including one woman--bounce around the shuttle's cabin and suit up for extra vehicular tasks while back on Earth, a young girl eagerly tracks the flight on television. While in the claim that heavy equipment--even the 12-ton Hubble telescope--can be lifted in space, Branley oversimplifies the effects of inertia and momentum, his choice of detail about conditions in space will surprise and delight readers.

内容简介

Have you ever dreamed of being an astronaut? Wondered what it might be like to see the sun set sixteen times in one day?

Open this book and be transported on an information-packed voyage aboard the space shuttle. True Kelley's kid-friendly diagrams and illustrations and Franklyn Branley's straightforward text reveal what astronauts eat, how they move, and what kinds of work they do in space.

　　这群贪婪行窃，胆大妄为，作恶多端的家伙究竟是怎么混进我家的呢？至今，我也不敢妄下断言。经多处详加考察，可能是顺着燃气管道攀爬而入。我记得，装修前，燃气管道立在一个上下通透的方形区域里；装修时，同楼上和楼下的方形区域没有封堵起来。因此，很有可能，他们就是在这样一个暗无天日的环境里神不知鬼不觉地进驻我家的。另外，还有一种可能，但可能性较小。有时，我们白天都在家会将大门敞开着，难道它们是如此趁人不备溜进来的？但这似乎跟老鼠的习性不大相符吧，毕竟它们是昼伏夜出的鼠辈啊！
