Description du livre Softcover. Etat : Good. Have you ever wondered why we put salt on icy sidewalks, or what makes grass turn yellow and why some things seem to "talk back" to you? Through personal investigation, youngsters can find answers to these and more than 30 other intriguing questions in this stimulating book by a former science consultant to the New York City Board of Education.By following simple instructions, children at the elementary school level can easily perform these experiments at home or in the classroom. Each project is clearly outlined, and carefully drawn illustrations indicate what materials are needed and how to set up equipment. (Parents will be happy to know that materials suggested for these research projects are safe, inexpensive and easily available.) By working with such common household items as a potato and a drinking straw, for example, researchers can learn how a tornado is able to drive a blade of dried grass into a tree trunk. Other challenging problems include designing an electric meter, burglar-proofing a school bag, producing animal sounds by vibration, preparing a timetable for nature, making an unusual window garden and learning where carbon dioxide can be found in the home.This book is ideal for the child who enjoys discovering answers to original experiments and solving scientifically intriguing problems. Even more important, each of these projects may spur the eager investigator on to further explorations in the thrilling field of scientific research. N° de réf. du vendeur SONG0486252353
