About the book


Strictly Based on Latest NCERT/CBSE Syllabus
Salient features of the book:
• The book has been prepared in accordance with the Termwise Bifurcated Course Structure.
• Each unit is supported by two sections: Term I and Term II.
• The Formative Corner section includes questions for Formative Assessment practice (Class Assignments, Class Response, Home Assignments, Group Discussion, Seminar/Symposium and Group Activity).
• The Summative Corner section includes a wide variety of questions for Summative Assessment practice (Illustrative Questions, NCERT Textbook and Exemplar Questions, Higher Order Thinking Skills (HOTS) and a large number of unsolved questions).
• Each Termwise Text Section includes two sets of model questions for Formative Assessments (Mid-term Paperpen Test) and one set of model questions for Summative Assessment (Term-end Examination).
• The book has been written in an informal, interactive style supported by a large number of well-labelled
illustrations, diagrams and solved examples.
• In-text pointwise summary is included for a quick revision of the portion covered.
Windows to the past and future developments in science are provided at appropriate places in the textbook to provide more relevance to the subject described therein.
