Children . Documentary

Maddie visits a building site. She uses a special camera to see how a big crane works to move heavy objects from one place to another. An animation shows how the hydraulic, hidden inside the boom arm, enables the crane to extend high into the sky. Next, Maddie visits a factory to see how bricks are made from clay, shaped by rectangular molds, and then fired in hot kilns for several days to make them strong.
