Grade 2-5 Cole and Degen have struck at the core once again to produce an exciting，attractive，and informative science book for young readers。Children who entered Ms。Frizzle’s classroom in The Magic School Bus at the Waterworks （Scholastic，1986），are in for another exhuberant，intriguing field trip。This time， it’s to the center of the earth。Surprises abound through each strata down to the very inner core where it is hot，hot，hot。The class collects rock samples before the bus is expelled from the earth’s core in a volcanic eruption。Illustrations are in watercolor cartoon format and attendant “balloons” contain pertinent information or students’humorous asides。There are also pages from students’reports on rocks。A tongue-in-cheek section at the end discusses the real and fantasy aspects of the book。Containing uncluttered text and illustrations， it is an anticipatory page-turner full of exciting adventure from school yard to volcano and back。Mary Lou Budd， Mil
The publication of Darwin’s The Origin of Species in 1859marked a dramatic turning point in scientific thought. The volumehad taken Darwin more than twenty years to publish, in part becausehe envisioned the storm of controversy it was certain to unleash.Indeed, selling out its first edition on its first day, The Originof Species revolutionized science, philosophy, and theology. Darwin’s reasoned, documented arguments carefully advance histheory of natural selection and his assertion that species were notcreated all at once by a divine hand but started with a few simpleforms that mutated and adapted over time.

Its profound ideas remain controversialeven today, making it the most influential book in the naturalsciences ever written—an important work n
The Origin of Species (英语) 平装 内容简介 'A grain in the balance will determine which individual shall live and which shall die...'. Darwin's theory of natural selection issued a profound challenge to orthodox thought and belief: no being or species has been specifically created; all are locked into a pitiless struggle for existence, with extinction looming for those not fitted for the task. Yet 'The Origin of the Species' (1859) is also a humane and inspirational vision of ecological interrelatedness, revealing the complex mutual interdependencies between animal and plant life, climate and physical environment, and - by implication - within the human world. Written for the general reader, in a style which combines the rigour of science with the subtlety of literature, 'The Origin of the Species' remains one of the founding documents of the modern age. 作者简介 Charles Darwin was born in Shrewsbury, England, on February 12, 1809 into a prominent middle-class f
