She is the author of over 40 books with sales totaling over 2 million copies. Klappentext An all-new collection of first-rate science experiments! Are you having a hard time coming up with a good idea for the science fair? Do you want to earn extra credit in your science class? Or do you just want to learn more about how the universe really works? Janice VanCleave's A+ Projects in Astronomy can help you, and the best part is it won't involve any complicated or expensive equipment. This step-by-step guide explores 30 different topics and offers dozens of experiment ideas. The book also includes charts, diagrams, and illustrations. Here are just a few of the subjects you'll be investigating: The size and rotation of celestial bodies Eclipses and the true movements of the sun The apparent magnitude of the stars Orbital eccentricity Meteors and artificial satellites You'll be amazed at how easy it is to turn your own ideas into winning science fair projects! Also available: Janice VanCleave's A+ Projects in Biology Janice VanCleave's A+ Projects in Chemistry Janice VanCleave's A+ Projects in Earth Science Zusammenfassung A collection of thirty experiments in astronomy for young adults.
