Alvarado, Patricio R.; Montalvo, Luis
This is the fourth book in a five-book physical science series on simple machines. The books are designed for Spanish-speaking junior high school students. This volume explains further refinements of the wheel which is introduced in volume three. The fourth volume explains principles behind gears and the relationship between velocity and force by suggesting experiments and posing questions concerning drawings in the book which illustrate the scientific principles. Propellors are also considered. Answers to the questions are provided in the book; an evaluation exam is also included. For other books in the series, see FL 002 897, FL 002 898, FL 002 900, and FL 002 901. (VM)
