Preface IMAX 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 has been involved in designing textbooks, workbooks and teacher companion books. Our books strive to ensure inclusiveness in terms of gender and diversity in representation, catering to the heterogeneous Indian classroom. IMAX presents the Traveller series, designed specifically to meet the requirements of the new curriculum released in November 2016 by the Council for the Indian School Certificate Examinations (CISCE). Guiding principles: The 2016 CISCE curriculum states the following as its guiding principles for Science: Theme-based learning Relating science learning to the daily-life experiences of students Focus on skill/process development Providing opportunities for knowledge construction Infusion of environmental issues into the content Each of these principles resonates with the spirit in which the IMAX textbooks, workbooks and teacher companion books have been designed. The IMAX team of pedagogy experts has carried out an intensive mapping exercise to create a framework based on the CISCE curriculum document. Key features of IMAX Traveller series: Theme-based content that holistically addresses all the learning outcomes specified by CISCE curriculum Opportunities for experimentation, analysis and synthesis of ideas and concepts Exposure to locally relevant environmental problem solving Focus on science-specific vocabulary building Promotion of participatory and contextualised learning through the engagement of all relevant stakeholders in the learning process All in all, the Traveller series aims to enhance the learning of science, development of scientific temper and curiosity towards scientific activities along with the inculcation of healthy habits for environmental protection. – The Authors NR_BGM_9789387552395-TRAVELLER-G05-SCIENCE-WORKBOOK-PART1_Text.pdf___2 / 32
