How Do You Lift a Lion? (Wells of Knowledge Science Series)
Grade 2-4?A basic introduction to levers, wheels, and pulleys. As two children lift a lion, pull a panda, and deliver a basket of bananas to a baboon party, Wells offers explanations for how and why these simple machines work. The hand-lettered text identifies technical terms such as fulcrum, force, friction, and other such words (also included in a glossary). One might quibble with some of the statements, such as "Leverage adds force to your own strength." Also the pen-and-acrylic cartoons are mediocre in quality and are merely adequate at depicting the concepts. A great idea with a fair-to-middlin execution.?Virginia Opocensky, formerly at Lincoln City Libraries, NECopyright 1997 Reed Business Information, Inc.
