Digging

Digging is the process of using some implement such as claws, hands, or tools, to remove material from a solid surface, usually soil or sand on the surface of the Earth. Digging is actually the combination of two processes, the first being the breaking or cutting of the surface, and the second being the removal and relocation of the material found there. In a simple digging situation, this may be accomplished in a single motion, with the digging implement being used to break the surface and immediately fling the material away from the hole or other structure being dug.

Many kinds of animals engage in digging, either as part of burrowing behavior or to search for food or water under the surface of the ground. Historically, humans have engaged in digging for both of these reasons, and for a variety of additional reasons, such as engaging in agriculture and gardening, searching for minerals, metals, and other raw materials such as during mining and quarrying, preparing for construction, creating fortifications and irrigation, and also excavations in archaeology, searching for fossils and rocks in palaeontology and geology and burial of the dead.

Play School (Australian TV series)

Play School is an Australian Logie Hall of Fame-winning educational television show for children produced by the Australian Broadcasting Corporation. It is the longest-running children's show in Australia, and the second-longest-running children's show worldwide. An estimated 80% of pre-school children under six watch the programme at least once a week. It is screened four times each weekday on ABC2's ABC4 Kids, at 6.00 am, 9.30 am, 12.30 pm and 3.30 pm (from 7 July 2014) and twice daily each weekend at 9.30 am and 3.30 pm.

History

Play School began production on 18 July 1966 based on a British programme of the same name. The first episode began transmitting that day, as the programme went out live. It has been produced continuously from this time. It has also launched the careers of several Australian actors and television presenters. Diane Dorgan and Don Spencer are the only regular presenters to appear on both the British and Australian versions, although Lorraine Bayly appeared in September 1972 as a guest storyteller on BBC's Play School. It was admitted to the Logies Hall of Fame on its 40th anniversary in 2006, in recognition of the strong influence the show has had in at least three generations of Australian children. Play School was the third show to enter the Hall of Fame in its own right, after Four Corners (1992) and Neighbours (2005), it is also the first children's show inducted in the Logie Hall of Fame.
