Escalar y saltar (Climbing and Diving) 6-Pack

The need for speed is the motivating factor in this engaging, Spanish book. Readers learn the history of travel from the very slow to the supersonic and beyond, including everything in between. They learn and discover the factors that influence motion for all types of vehicles: land, air, and water alike. They also learn different ways to measure speed and read about energy uses for different vehicles. With greater speed comes greater risk. Readers learn how engineers are always seeking new and better ways to keep people safe as they travel faster and go farther.

This Spanish-translated book will be a hit with both thrill seekers and with those who prefer to stay safely on the ground. After an introduction to Newton's three laws of motion, readers learn the mechanics of various amusement park rides including roller coasters, Ferris wheels, merry-go-rounds, and gravity rides. They learn how to measure motion, and how kinetic and potential energy apply to their favorite rides. This 6-Pack includes six copies of this title and a lesson plan.
