Do You Know?

PëRMBLEDHJE

Maddie is at a building site and finds out how tracks work to help a digger move up and down mounds of earth. Maddie wears some special shoe attachments to show us how the digger's tracks work to stop it sinking into the soil. Then she attaches a special camera to the digger, to see it in action as it lifts the soil high into the dumper truck! Next, she visits a wellie factory to see how wellies are made.
