Laboratory Manual Science Class Xth - Includes Experiments and Viva - Voce  (English, Paperback, unknown)

Experimentation is the most prominent method to prove a theory. CBSE conducts Practical Exams along with theoretical exam to test the scientific aptitude of students. It is because the conclusions that are observed and verified in real time are authentic and easy to retain. CBSE Class 10th, Science Lab Manual includes guidelines for Experiments, Activities and Projects in accordance with the curriculum. Each practical is supported with relevant theory, procedure, observations and calculation, error rectification results, precautions and viva voce in the format to be followed in the laboratory. The book serves as the step by step guide for conducting experiments explaining the relevance of each step The book covers all aspects of the experiment in such a way that students will not need to refer any other book for explanations of the concepts.
