How are buildings torn down and built up? Construction workers use large vehicles to get the job done. Excavators rip off pieces of buildings and dig deep holes. Wrecking balls hit buildings so their walls fall down. Flatbed trucks bring new materials to the site. Every construction vehicle has a purpose when people tear down or create buildings.
Some vehicles work on farms. Others go into space. They may even dive deep below the ocean. No matter where they go, vehicles get the job done. Vehicles on the Job look at these machines in action. Discover how vehicles help save lives, construct buildings, and make scientific discoveries using science, technology, engineering, and math. Each book contains a glossary, an index, and places to go for more information.
