This book is based on the syllabus prescribed by the CBSE. The books fully conform to the vision of the National Curriculum Framework (NCF). This course has been designed for schools teaching a basic course in science at the foundational level. The series focuses on understanding the environment, different life processes, different food we eat and how to maintain a healthy body and mind. This series aims to foster curiosity and investigative approach among children. It also helps to build a scientific temper in them. Efforts have been made to bridge the gap between textual knowledge and the everyday life experiences of children. This series is integrated with learning, assessment and evaluation tools. Social and Emotional Learning (SEL) and Sustainable Development Goals (SDG) have been thoughtfully integrated with text and various features to connect the concepts in sciences to the life outside school.
