CBSE Class 10 Science Practical Important Questions<\/span><\/h2>\n

Chemistry:<\/b>\u00a0<\/span><\/p>\n

In Viva, questions are generally asked from the basic theory portion related to practicals. So focus on the related terminology, chemical formula\/composition, properties, etc.<\/span><\/p>\n

For example, if you are studying for Practical Q. No. 3 \u2018the action of different metals on the various salt solutions\u2019, then you should know the definition of displacement reaction, activity series, and its characteristics.<\/span><\/p>\n

Biology:\u00a0<\/b><\/p>\n

In Viva, general application and significance-based questions are asked from the practicals such as the preparation of temporary mounts, and the study of various asexual modes of reproduction. <\/span>For practicals related to the topic of Photosynthesis, a depth study of the procedure and key roles of certain chemicals added should be remembered.<\/span><\/p>\n

Physics:<\/b><\/p>\n

Generally, application-based questions are asked in viva. So focus on concepts and their applications. It is also important to remember the definitions.<\/span><\/p>\n

Students should remember the ray diagrams, circuit diagrams as well as formulae which are generally used in practicals.<\/span><\/p>\n

Students should have adequate knowledge of apparatus and instruments.<\/span><\/p>\n

Key tips to remember:<\/h3>\n
    \n
  • Read experiments carefully and understand the underlying concept.<\/span><\/li>\n
  • For writing answers, learn the stepwise procedures and write them in the passive voice.<\/span><\/li>\n
  • Don\u2019t cram readings\/observations. Conduct your experiment with a calm mind and write the readings\/observations obtained.<\/span><\/li>\n
  • Be thorough with the diagrams and draw neat and well-labeled diagrams wherever required.<\/span><\/li>\n
  • Be confident and calm while performing experiments.<\/span><\/li>\n
  • While performing Chemistry experiments, handle the equipment and chemicals carefully as some of these chemicals are strongly reactive.<\/span><\/li>\n
  • Observe the readings carefully and don\u2019t forget to use standard conventions and SI units while writing answers.<\/span><\/li>\n<\/ul>\n

    Backed with practice and a regular learning schedule, these tips will surely help you to perform outstandingly in your practical exams.<\/span><\/p>\n

    Here are some interesting tips on how to prepare for your science practical exams:<\/p>\n

    Pay attention in classes
    \nMake proper notes
    \nBe thorough with diagrams and circuits
    \nPractice well
    \nBe confident during the practical examination<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t

    2. What if we fail in practicals?<\/h3>\n\t\t\t\t\t
    \n\t\t\t\t\t\t

    In case a candidate has failed in practical he\/she shall have to appear in theory and practical irrespective of the fact that he\/she has already cleared the theory examination.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t

    3. What is the importance of a practical exam?<\/h3>\n\t\t\t\t\t
    \n\t\t\t\t\t\t

    A practical exam strengthens the comprehension and understanding of a particular subject. Even though theoretical education makes use of textbooks and research papers, applying that knowledge in the real world and having a first-hand experience with it will help you understand it in a much better way.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t

    4. Are practical marks counted?<\/h3>\n\t\t\t\t\t
    \n\t\t\t\t\t\t

    Practical marks are not counted separately. The combined score with theory is taken. Practicals do help to increase your percentage.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t

    5. Can practical marks be changed?<\/h3>\n\t\t\t\t\t
