Preface IMAX Program partners with schools, supporting them with learning materials and processes that are all crafted to work together as an interconnected system to drive learning. IMAX Program presents the latest version of the Alpine series – updated and revised after considering the perceptive feedback and comments shared by our experienced reviewers and users. The Alpine series endeavours to be faithful to the spirit of the prescribed board curriculum. Furthermore, to facilitate comprehensive coverage, improved understanding of diverse themes and ease of implementation, the EVS curriculum has been split into EVS – I (Science) and EVS – II (Social Studies). Our books are split into two parts to manage the bag weight. They also strive to ensure inclusiveness in terms of gender and diversity in representation, catering to the heterogeneous Indian classroom. The Alpine EVS – I (Science) textbooks and workbooks offer the following features:  Interactive content that engages students through a range of open- ended questions that build curiosity and initiate exploration  Opportunities for experimentation, analysis and synthesis of ideas and concepts  Exposure to locally relevant environmental problem solving  Effective use of visual elements to enable learning of structures, processes and phenomena  A focus on subject-specific vocabulary building  Integrated learning of values and life skills  Promotion of participatory and contextualised learning through the engagement of all relevant stakeholders in the learning process Overall, the IMAX Alpine EVS – I (Science) textbooks, workbooks and teacher companion books aim to inculcate healthy habits, skills and values that promote environmentally sensitive and culturally responsive democratic citizenship among students. – The Authors Alpine_Contents.indd 2 9/7/2018 11:09:54 AM
