A New Approach to ICSE Chemistry for Class X has been revised in accordance with the latest syllabus prescribed by the Council for the Indian School Certificate Examination, New Delhi for Class X. The main strength of the book lies in the presentation of scientific content which has been so arranged that the topics are linked with each other and do not cause any unnecessary burden on the mind of the student. Salient features of this book are as follows. * Clear, simple and easy language * A large number of chemical reactions along with experimental observations * Full-sized diagrams, as expected from a student in the examination * Topic-wise Video Lectures as a support for effective learning * Concepts supplemented by suitable day-to-day examples * Periodic Table showing mass number; atomic number of various elements along with the list of actual names of the elements. * Highlighted important terms and definitions * Well-designed exercises to assess conceptual, reasoning skill and application-based learning as per the latest recommendations of ICSE board * Solved numerical problems at the end of each chapter to help the students solve numericals on their own * A chapter on Practical Chemistry to help students in their laboratory work. * The latest Solved ICSE Specimen Paper has been given. * Scan QR codes given at the end of each chapter to get the solution of chapter-wise ICSE Board Examination Questions. We hope this book will prove useful to fellow teachers and students. Suggestions for further improvement of this book shall be gratefully acknowledged. -Author

The book "A New Approach to I.C.S.E. Chemistry for Class IX" has been written in accordance with the latest syllabus prescribed by the Council for Indian School Certificate Examination, New Delhi. The book is divided into five distinct parts : 1. The first part constitutes chapters on, The Languages of chemistry; Chemical Changes and Reactions; and Water, to give an idea to the students about the diversity of matter. 2. The second part constitutes chapters on Atomic Structure and Chemical Bonding and The Periodic Table. This part will help the students to understand unity in diversity of matter. It further explains the rules required for reaction between various forms of matter. 3. The third part constitutes chapter on Study of the First Element -Hydrogen and Study of Gas Laws. This will familiarise the students with element hydrogen and their chemical properties. It further explains the behaviour of gases under changes of temperature and pressure and also provides explanation in terms of molecular motion. 4. The fourth part deals with Atmospheric Pollution. 5. The fifth part deals with Practical Chemistry. The salient features of the book: • Large number of chemical reactions are described with experimental observations. • Important points have been highlighted for location of precise answers. • All definitions and other important points are highlighted. • Diagrams are made simple and more Informative. • In the chapter on the language of chemistry, a new method has been introduced for balancing chemical equations. This method Is based on atomic numbers which Is fundamental property of the elements. • A chapter on Practical Chemistry is added to help students for laboratory work. • Questions have been added chapter-wise under the heading Question Bank for the benefit of students. The solution can be accessed through QR Code given at the end of each chapter. • Periodic Table showing mass number; atomic number of various elements along with list of actual names of the elements is provided. • A Specimen Paper (Solved) has also been included through QR Code, for the benefit of students. • Annual Examination Paper 2019 (Solved) has been given through OR Code. • Model Test Papers 1 to 5 (Unsolved) have been given through OR Code. We hope this book will prove very useful to the students and teachers. Suggestions and constructive criticism for the further improvement of the book would be gratefully acknowledged. -Author

A New Approach to I.C.S.E. Physics (for Class X) has been revised in accordance with the latest Syllabus prescribed by the Council for Indian School Certificate Examination, New Delhi for Class 10. The main strength of this book lies in the scientific content and rearrangement of the prescribed syllabus, such that the topics are linked to each other and do not cause any unnecessary stress on the mind of students. Emphasis has been laid upon mastering the fundamental principles of Physics, rather than specific procedures and on selecting the areas of contemporary interest rather than of past interest. The main strength of the book lies in the subject matter and the experience that a student will get in solving difficult and complex problems of Physics. Salient features of this book are as follows : • Thoroughly revised and upgraded. Written in new format with figures, examples and definitions highlighted. • Full-size diagrams are given. The size of diagrams is the same as is expected from a student in examinations. * Topic-wise video lectures are given as a support for effective learning. * At the end of each chapter, there are given enough Solved Numerical Problems. This will help the students to solve numericals on their own. * Most of the numerical problems are of contemporary interest and are in Sl units. The motive has been to evaluate the application of principles rather than to test the mathematical skill of students. * ICSE Specimen Question Paper has been given. * Scan QR codes given at the end of each chapter to get the solution of chapter-wise ICSE Board Examination Questions. We hope that this book would prove very useful to fellow teachers and students. Suggestions and constructive criticism for the improvement of the book are welcome and shall be gratefully acknowledged. -Author
