This invaluable guide to physics projects, written for middle and high school students, details how to put together projects that showcase key physics concepts. In this latest volume in her successful series of science fair project books, Janice VanCleave provides thirty comprehensive projects-on measurement, force and motion, states of matter, energy, and electricity-that come complete with illustrations, charts, diagrams, and suggestions for original projects on related topics. Whether students want to work with pendulums, lenses, or parallel circuits, this book provides the inspiration and hands-on help they need to assure science fair success.

Janice VanCleave (Riesel, TX) is a former elementary and high school science teacher who now spends her time writing and giving science workshops. She is the author of more than forty children's science books, with sales totaling more than 2 million copies.

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 physics class? Or do you just want to learn more about how physics affects our everyday lives? Janice VanCleave’s A+ Projects in Physicscan help–and you don’t even need any complicated or expensive equipment.

This step-by-step guide features 30 different topics in physics and dozens of winning experiment ideas. Packed with helpful illustrations and charts, the book helps you explore key physics concepts, including:

• Angular measurement
• Linear intertia
• Transfer of energy
• Light rays
• Sound waves
• Electricity and magnetism
• Terminal Velocity
• And much more

This inspirational guide gives you all the hands-on help you need to turn your own ideas into science fair projects.
