Pupils at Colburn Community Primary School chose to swap their red noses for blue and yellow outfits to raise money for the Ukraine refugees.
School council representatives Jake and Keevie researched the charity Sunflowers of Peace after hearing about it on BBC Newsround.
They found out that the charity was raising money for medical supplies for paramedics and doctors on the frontline in Ukraine.
The charity uses the sunflower in its name as it is the national flower of Ukraine and symbolises hope and resistance.
Pupils paid to wear their own blue and yellow clothes and purchased cookies made by their school cook, decorated with the Ukraine flag.
Head teacher Jane Knowlson said: “I am very proud of our pupils; they have shown compassion for the people of Ukraine and initiative in organising their fundraising activities.”
Year 5 pupil Jake said: “It’s good to help the Ukraine people because we’ve all seen the sad pictures of Ukraine children carrying everything they own in a bag.”
