Science Discoveries on the Net: An Integrated Approach
Publisher: Libraries Unlimited | ISBN: 1563088231 | edition 2000 | PDF | 313 pages | 11 mb
Adding the Internet to classroom lessons can be a daunting task for teachers and librarians. The tried-and-true methods of evaluating traditional materials (books, magazines, videos) don't translate as easily to Web sites. Fredericks offers not only lists of Web sites, but also ideas on how to use the Internet as part of a larger classroom or research activity. Part one is fairly general, including an introduction to teaching science, as well as tips on teaching with online resources. Included are Web sites that offer lesson plans, suggested search engines, and an example of a parental consent form. The second part, which makes up the bulk of the book, offers science units. Each one focuses on a particular subject area, covering specific topics in the life, physical, earth, and space sciences and the human body (sample subjects include food chains and webs, magnetism, volcanoes, asteroids, and the respiratory system). Each unit includes a list of Web sites, suggested research questions for students, a short bibliography, and a few activities. There is nothing extraordinary about this book, but it's a comprehensive guide for those who are new to the information superhighway, and it's refreshing to see that the author includes print material in his suggested lesson plans.

Joseph A. Angelo "Rockets (Frontiers in Space)"
Published by Facts on File | Publication date : September 2006 | ISBN : 0816057710 | PDF | 208 pages | English | 5.12 MB
From the fire arrows of ancient China to the ballistic missiles developed during World War II to the rockets of the 20th century, the development of modern launch vehicles have forever changed the destiny of humankind. These sophisticated propulsion machines harness the action-reaction principle of physics and allow humans to enter a world that was previously denied them: outer space.
In an eye-opening volume on this technological evolution, "Rockets" explores the historical events, scientific principles, and technical breakthroughs that now allow complex launch vehicles to send satellites into orbit around Earth. Sidebars are strategically placed throughout the book to provide expanded discussions of fundamental scientific concepts and rocket engineering techniques. Capsule biographies of important rocket scientists and aerospace engineers are also included to emphasize the human aspect of these technological developments.
Chapters include: From Fire Arrows to Mars Missions; Rocket Propulsion Fundamentals; Pioneering Rocket Planes; Military Missiles and Rockets; Space Launch Vehicles; Launch Sites; Upper-Stage Rockets and Orbital Transfer Vehicles; Sounding Rockets; Nuclear Rockets to Mars and Beyond; Electric Propulsion for Deep Space Missions; Advanced Propulsion Systems for the 21st Century; and Interstellar Probes and Starships.
