The National Curriculum Framework for school education (NCFSE) developed by NCERT emphasizes that learning should be facilitated through activities from the very beginning of school education. These activities may involve the use of concrete materials, models, patterns, charts, pictures, posters, games, puzzles and experiments. With this in mind, CBSE has endeavoured to introduce the idea of Science & Mathematics Lab Manualsin schools. Oswaal Lab Manual for Science Classes IX & X has been written so as to supplement the need of the students to prepare for lab work and learn science practical during the entire year. This book is strictly according to the latest CBSE guidelines, and contains more than sufficient viva voce questions and brief description of each activity/experiment, which help students in practicing and completing the lab work. All activities and experiments are always checked twice to precision. Practically, this book provides students everything they need to learn during their lab work. Since we believe in continuous improvement, hence this book has been written with accuracy as well as updated as per CBSE guidelines and reviewed at different tiers by 'Oswaal Editorial Board'. Some of the Oswaal Lab Manual benefits are: 🧪 Activities and experiments: as specified in latest CBSE curriculum for better understanding. 🔎 Theoretical concepts: provide brief description about Experiments/Activities. 🧩 Viva-voce Questions: for better practice and learning. 🧠 Group Activities and Projects: to facilitate extension of learning to real life situations. 📖 Mock test papers: for extra practice. 📽️ Video links: for a Digital Learning Experience. We are sure that this book will serve as a perfect teaching guide for the teachers and good lab manual for the students.It is expected that every reader willtake full advantage of our knowledge and experience.
