CBSE Practical Notes

The CBSE Practical Notes have been included in the Class 9th, 10th, and 12th Science Syllabus to familiarize students with basic laboratory tools and procedures. By watching the changes that occur in front of their eyes while doing the activities, students will gain a greater comprehension of the subject. They can progressively enhance their basic scientific concepts while practicing things in the lab. Also, their curiosity in science will be awakened, students will learn to ask probing questions and begin to think scientifically.

Students willing to get complete marks in CBSE Science need to study the practical syllabus for Class 10 Science. They should be aware that the Class 10 Science theory paper is worth 80 points, with internal assessments accounting for 20 points. The internal assessment includes the Science practical. However, their significance does not end there. The practical syllabus is significant in Class 10 because it aids in the understanding of science concepts.

How are CBSE Practical Examination conducted?

While appearing for CBSE Practical Examination the following points should be noted by students:

  • The CBSE Practical Exams or Internal Activities for Internal Assessment will be administered by the various schools.
  • It should be mentioned that the date of the CBSE Internal Assessment will be determined by teachers and administrators. As a result, there will be no specific CBSE Practical Exam Admit Card issued.
  • The CBSE Practical 2021 examinations for Class 10 and Class 12 must be held within the specified time frame, according to the officials. Authorities from the school must adhere to the timetable set forth by the regulators.

CBSE Practical

For CBSE Class 10 pupils, each topic is divided into two parts: internal test and external examination, each worth 20 and 80 points. The practical test in CBSE Class 10 is just for the subject of Science. External invigilators will not be assigned to the practical exam by the authorities.

The practical exam tests for Physics, Chemistry, as well as Biology for Classes starting from 6 to 8, 9, 10, 11, and 12 can be found by clicking on the links below.

PDF format of CBSE Practical Exam Syllabus for Class 12

There are two main types of grading procedures in the CBSE Internal Assessment for Class 12. Certain CBSE Class 12 subjects have 30 points for internal test and 70 points for external examination, while others have 20 points for internal test and 80 points for external examination.

Regulators will not assign an external invigilator to the CBSE Internal Exam of topics with only a 20-point Internal Assessment. However, for the examinations, which are worth 30 points, authorities will choose an external supervisor to assess the practical exam.

  • Next, theory outlines the fundamental ideas, rules, or hypotheses that the experiment is founded on.
  • The Material required list includes a list of all of the equipment, measurement devices, and other things required to perform the experiments.
  • Within the procedure section, the methods for performing the experiment are listed in the correct order. In addition, diagrams are made whenever necessary to illustrate the experiment in a pictorial format.
  • In the observation section, throughout the experiments, all observations are recorded. Measurements are recorded in the form of a table for better display. Every measure is presented in the appropriate units.
  • Observation includes all the equations are used to calculate based on the findings. Statistics are also drawn in some trials.
  • The results and Discussion section discusses the test’s final outcome.
  • The final Precautions and Error Sources lists all of the safeguards that were taken when conducting this study. Under this section, the sources of error that happen as a result of equipment limitations are also listed.

What is the syllabus for CBSE Class 10 Science Practical Examination?

The five subjects in the CBSE Class 10 Science curriculum include Chemical Substances, Natural Phenomenon, Effects of Current, Nature, and Behaviour, World of Living, and Natural Resources. In the practical syllabus, CBSE has given a list of experiments on these subjects. You must perform all these experiments, document the findings, and enter them into the practical file or laboratory manual. Students must also put the entire technique of the experiment in the file and, if necessary, provide figures for deeper comprehension. Here are some of the experiments that are included for CBSE Science Class 10 students:

  • To examine stomata, Students need to prepare a temporary mount of a leaf strip.
  • Binary fission in amoeba and budding in yeast and hydra were studied utilizing prepared slides. Observing the reactions of metals in salt solutions.
  • Combining, decomposition, displacement, and double displacement are the four types of reactions.

  • Whatever measures you took while carrying out the experiments.

FAQ – CBSE Practical Notes

Do students fail in CBSE Class 10 practical examination?

If you finished the exam, there’s a good possibility you will be given a grade based on how well you did. If students skip the exam, however, the school may not offer students any credit. If you really want to earn a perfect score on the practical test, you must completely learn all of the experiments, keep track of the practical files, and study well for the viva.

Are CBSE Practicals hard?

Students do not really need to bother too much about the practical examination; they are usually simple and the majority of the students receive decent grades. Sometimes students receive low grades; it is not because of how difficult the practical was, but rather because they are generally below standard or have poor attendance.

What is the best way to write CBSE Class 10 Science Practical exam?

Every CBSE Class 10 Science Practical examination should be presented impersonally in the past tense. While writing impersonally, personal pronouns should be omitted; such expressions comprise personal terms including we, I, you, they, and he or she, etc.

Are Practical marks added in class 12?

Class 12 CBSE practical examinations are conducted in the institutes with an internal as well as external examiner. The question papers are prepared by external teachers, who also assign the grades. With theory papers, the practical scores are included in the mark sheet.

How can I prepare for the Class 10 Science practical viva?

When an external examiner asks students things during the viva, most students are terrified. However, there is no need to be concerned. Just take the time to understand all of the experiments and study the theory from the NCERT book that goes along with them. Try to ensure that all of the specifications of your practicals are correct. Make an effort to respond calmly. Even if you don’t have a perfect answer, attempt to talk about what you understand about the subject.

How can you get full marks in the CBSE class 12 practical examinations?

Certain things are important to make sure that you perform your best in your CBSE class 12 practical examinations. Firstly, it is important to be able to read and understand diagrams and circuits. Start preparing the tests by visualizing and sketching rough diagrams.
Be self-assured during the practical exam. A student should be comfortable with whichever topic the examiners assign; also make your perceptions are acute.

How do I study for practicals?

Recognize the subjects that will be discussed in the practical sessions. Before taking the examinations, go over all these terms and concepts at least two times. Clarify each and every doubt that developed during the mock practical sessions before taking the practical exam. Remember that appropriate practices and safety measures should be practiced for best performance.
