Books in Reading Essentials in Science series

Science Essentials Solar System helps explain our solar system and the space beyond to aspiring astronomers. At the same time, the book reinforces cross-curricula skills in science and reading. Young learners will read lively passages about space, strengthen reading, vocabulary, and language arts skills, and play games that reinforce learning. Cutout fact cards, a solar system poster, and stickers are included. Appealing illustrations, easy-to-understand directions, and varied creative activities make learning about the solar system fun and easy. Science Essentials Solar System is the most complete book that offers: • Passages about black holes. • Cutout fact cards and games. • Vivid, full-color illustrations to spark the learner's interest. • An answer key to measure student performance.

Designed by leading experts in the field of science education, this hands-on science workbook provides aspiring scientists, in fifth and sixth grade, the tools they need to become actively involved with science. Science Essentials leads children through the processes of observation and experimentation, prediction and drawing conclusions. It covers all the essential science topics like the scientific method, the animal kingdom, the human body, genetics, animal and plant cells, plants, food chains and webs, environment, geology, meteorology, the solar system, elements, electricity, sound, and simple and compound machines. Step-by-step lessons and hands-on experiments are provided in an exciting and easy-to-follow way. A periodic table of the elements poster with stickers of the individual elements are included. Science Essentials is the most complete book that offers: • Challenging and motivating science investigations. • Hands-on approach to science learning. • Complete directions and examples to encourage independent study. • Vivid, full-color illustrations to spark the learner's interest. • An answer key to measure student performance.

Heart of Darkness describes the incredible saga of humankind's quest to unravel the deepest secrets of the universe. Over the past thirty years, scientists have learned that two little-understood components--dark matter and dark energy--comprise most of the known cosmos, explain the growth of all cosmic structure, and hold the key to the universe's fate. The story of how evidence for the so-called "Lambda-Cold Dark Matter" model of cosmology has been gathered by generations of scientists throughout the world is told here by one of the pioneers of the field, Jeremiah Ostriker, and his coauthor Simon Mitton. From humankind's early attempts to comprehend Earth's place in the solar system, to astronomers' exploration of the Milky Way galaxy and the realm of the nebulae beyond, to the detection of the primordial fluctuations of energy from which all subsequent structure developed, this book explains the physics and the history of how the current model of our universe arose and has passed every test hurled at it by the skeptics. Throughout this rich story, an essential theme is emphasized: how three aspects of rational inquiry--the application of direct measurement and observation, the introduction of mathematical modeling, and the requirement that hypotheses should be testable and verifiable--guide scientific progress and underpin our modern cosmological paradigm. This monumental puzzle is far from complete, however, as scientists confront the mysteries of the ultimate causes of cosmic structure formation and the real nature and origin of dark matter and dark energy.
