Sound and HearingEarly in the 17th century, Francis Bacon decided that the best way to learn about the world was to discover things for oneself. Since then, science has been a marriage of observation and experimentation. The experiments contained in each chapter allow young scientists to investigate basic principles using common household materials and easy-to-follow instructions. The titles are filled with dozens of color photographs that illustrate experiments and provide a glimpse of everyday and extraordinary uses of the subject. In addition, engaging features such as "Did You Know?" boxes provide fascinating facts. The "In Focus" sections offer in-depth looks at specific features of each subject. "In The Real World" boxes highlight pivotal experiments by real scientists. |
