During the Autumn term of 2010, schools were invited to join the A History of the World project by taking part in The Relic Challenge*. It was a campaign to encourage schools to learn history through objects.
Teachers asked their classes to bring in man-made objects from home and then chose up to five objects to upload to the A History of the World website. Judges from the BBC and museum partners then selected 20 schools objects for a series of programmes for BBC Radio 7.
You can listen again to The Relic Challenge on The 4 O'clock show with 1 object each day starting on 9 January 2012.
Listen to the twenty final programmes now.
