The five, who join Saddleworth School in September from St Annes CofE Lydgate, rose to the challenge as part of the school's 'Vision of Hope Challenge'.
Millie Foster said: "We were chatting one day and wondering what to do when Alice Winfield came up with the idea of a litter pick."
This came after hearing reports from local residents on social media that a couple of the girls' favourite hangouts were starting to look a mess with litter.
So, backed with support from the local community and Oldham Council, the team, armed with litter pickers, set off on a wet afternoon collecting rubbish and litter from around the villages.
Millie said:"We collected lots of crisp packets, drinks bottles and dog poo bags which was pretty disgusting.
"We even found a lost iphone later and reunited it with its grateful owner."
And the girls declared that despite taking a soaking, morale was high and they were glad to be able to support their local community.
