Good for science fair project ideas, these updated books are filled with experiments generally requiring only easy-to-obtain materials. In each volume, clear black-and-white drawings accompany the thirty-five-plus projects, which include making a toy telephone, observing the behavior of waves, and measuring surface tension. "Exploring on Your Own" sections expand the scope. Some familiarity with terms is assumed. Reading list, websites. Ind.
