The challenge targeted middle and high schools throughout England and Scotland, inviting them to take part in the Tizer Can Challenge for the 2002-2003 school year. Schools were asked to collect aluminium drinks cans in return for which they would have the chance to win prizes for their schools.  End of term prizes included certificates, Tizer goodie bags and concert ticket vouchers.  End of year prizes included Yamaha electric keyboards and Yamaha electric guitars, can recycling bins, plus a star prize of a party for all pupils at the overall winning school. The participating schools also received money in return for the cans they collected, which further encouraged them to recycle.  Schools either put the funds back into their school, or donated it to a charity of their choice. 230 schools from eight different regions throughout the country signed up to the challenge, involving around 300,000 pupils.  Nearly four tonnes of aluminium cans – that’s nearly a quarter of a million empties – were collected by the participating schools.
