The aim of the competition was to help children, teachers and parents think about what science and surgery mean to them in order to promote and develop an interest in science among younger children.
The overall winner was Kyann from St Nicholas' Primary School, who won an individual prize of a skeleton with removable organs and an additional prize of an educational anatomy model for the school.
The winner from St Michael's CE Primary School was Anees and the joint runners-up were Hajra from St Nicholas' and Aaron from St Michael's.
The winners were announed over assembly at the schools to the surprise and delight of the children.
Katharine Helkin, the Year 6 teacher from St Michael's CE Primary School, commented: 'Anees was over-the-moon. You chose a boy who does not often win competitions or come 1st place, so it was really special that he won. He also loved the prize.'
Some of the beautiful illustrations were displayed on the NDS stand at the Oxfordshire Science Festival on Saturday 25 June in Oxford city centre (Broad Street).
Emma Morris, who is a researcher in bone oncology and the Public Engagement Coordinator for the department, commented: ‘We were impressed by the standard of the art work, and there was such a wonderful array of entries showing how science is related to surgery. The message about how scientific work improves surgical practice, which in turn makes a huge difference to people’s lives, was depicted very well in the winning drawings’.
