  Designed specially for young independent readers, aged between 6 and 8, this wide-ranging collection called Perspectives aims to provide new perspectives on the topics being studied. The series combines core non-fiction features (including a real emphasis on research skills) with a visually stunning design that encourages readers to look at these topics in a different way. Incredible inventions are based on the most basic principles, and yet simple the machines featured in this series can extend to extraordinary levels of complexity.
