Pupils and teachers at a school in Rushden have been raising money to buy a piece of life-saving equipment for the school.
As part of National Science and Engineering Week, South End Infant School ran events to highlight the importance of keeping the heart healthy and to raise money for Arrhythmia Alliance, the heart rhythm charity.
The school had to raise £400 for the charity to pay for a defibrillator for the school that will be used within the school and local community.
The children took part in a 10 Minute Madness sponsored event where they had to do 10, one-minute sports activities. Parents and carers were invited into school to join their children in circuit training to learn how to keep their heart muscles fit and strong.
The school hopes to be one of the first premises in the local area to have a defibrillator.
