All the factors such as physical, geographical, chemical, biological, and ecological which affect human life and its existence on this planet are called environment. Environmental studies describe the interrelationships among organisms, the environment, and all the factors, which influence life on earth, including atmospheric conditions, food chains, the water cycle, etc.Important PointsEVS, at the primary stage, is an integrated subject area that draws upon insights from sciences (physical, chemical, and biological), social studies (history, geography, political science, sociology, etc), and environmental education (protection and conservation).It is aimed at developing in children a holistic or an integrated perspective of the environment where he/she lives in. Hence the syllabus of EVS based on the NCF 2005 is designed to provide an integrated perspective that draws upon insights from sciences, social sciences, and environmental education.It is important to be acquainted with the organization of the syllabus in order to better understand and use the textbooks.?In classes 1 and 2, the environment subject should be taught as a composite subject.Developing skills like Observation skills, Classification skills, Survey skills, Mapping skills, and communication skills are developed in students with the help of the integrated nature of E.V.S. Development of scientific attitude in students.Development of moral value.Hence we conclude that the nature of EVS is Integrated.Additional Information Disciplinary is not included in the nature of EVS because the nature of evs is multi-disciplinary, not disciplinary.
