In Trains, early fluent readers learn about the science, engineering, and physics behind locomotives. Vibrant, full-color photos and carefully leveled text engage young readers as they learn about these exciting machines. A diagram illustrates parts of a train, and an activity offers kids an opportunity to extend discovery. Children can learn more about trains using our safe search engine that provides relevant, age-appropriate websites. Trains also features reading tips for teachers and parents, a table of contents, a glossary, and an index. Trains is part of Jump!'s How Does It Work? series.
