Questions are the root cause of success. The more new & authentic questions you will have, the more new & authentic knowledge you will have. Considering this fact, the Department of Education in Science & Mathematics (DESM) with an aim to improve the quality of teaching/learning process in schools has made an attempt to develop resource books of Exemplar Problems in different subjects at secondary and higher-secondary stage. These specialized resource books named NCERT Exemplars are not meant to serve merely as question banks for examinations but are primarily meant to discourage rote learning.
The first and the only books of its kind by Arihant Publications is an attempt at providing comprehensive guide to NCERT Exemplar Problems-Solutions for Class 6th to 12th. The present book for Class 8th Science contains different types of questions of varying difficulty level. Also detailed explanation for comprehensive understanding has been given for all objective and subjective problems. The present book has been divided into 18 chapters namely Crop Production & Management, Microorganisms: Friend & Foe, Synthetic Fibres & Plastics, Materials: Metals & Non-Metals, Coal & Petroleum, Combustion & Flame, Conservation of Plants & Animals, Cell: Structure & Functions, Reproduction in Animals, Reaching the Age of Adolescence, Force & Pressure, Friction, Sound, Chemical Effects of Electric Current, Some Natural Phenomena, Light, Stars & Solar System and Pollution of Air & Water. The problems provided in the book will test comprehension, information recall, analytical thinking and problem-solving ability, creativity and speculative ability. Detailed explanation has been provided for all objective and subjective problems covered in the book. The book will also be highly useful for school examinations and to build foundation for entrance examinations.
