Based on the National Curriculum Framework (NCF) 2005, at the national level, Environmental Education (EE) is introduced at the elementary education level as Environmental Studies (EVS). EVS for classes III to V deals with the study of our environment (physical, biological, social and cultural) with an emphasis on its preservation and conservation. EVS at the elementary level is an integrated subject which draws upon insights from sciences (physical, chemical and biological), social studies (history, geography, civics, etc) and environmental education (protection and conservation). Thus, the integrated nature of EVS is to reduce the curriculum load and help children to learn specific topics meaningfully.
