The children from Locks Heath Junior School, Southampton, had perceptive and thoughtful views about "Why science?" In this paper, the children share their thoughts about what science is and why they think it is important. This paper presents only a small selection of their far-ranging thoughts on the subject. The emphasis on investigating in the National Curriculum appears to have had some impact in enabling children to see the evolving and changing nature of science and the children at Locks Heath obviously felt they played an important role in this process.
