Jackhammers
Jackhammers pound through cement and rock and are one of the most recognizable (and audible) machines at construction sites. Machine-loving readers will build vocabulary as they learn how jackhammers work and the significant jobs they do. Action-packed photographs show jackhammers making fast work of blocks of concrete and rock.
