The CBSE syllabus for Class 12 Physics Practical includes a total of 30 marks, divided into two sections:
- Section A: 6 experiments, each carrying 7 marks
- Section B: 6 activities, each carrying 5 marks
In addition to the experiments and activities, students are also required to complete an investigatory project, which carries 3 marks.
The experiments and activities in the CBSE Class 12 Physics Practical syllabus are designed to help students develop their understanding of the concepts of physics. They also provide students with an opportunity to apply their theoretical knowledge to practical situations.
The experiments and activities are divided into two sections:
- Section A: Experiments that are more theoretical in nature, such as the determination of the resistance of a wire or the study of the motion of a projectile.
- Section B: Activities that are more practical in nature, such as the construction of a simple electrical circuit or the measurement of the speed of sound.
The experiments and activities in the CBSE Class 12 Physics Practical syllabus are not difficult to perform, but they do require careful planning and execution. Students should carefully read the instructions for each experiment or activity before they begin. They should also make sure that they have all of the necessary materials and equipment.
The practical file is a notebook in which students record their observations and results from the experiments and activities they perform. The practical file should be neatly handwritten and should be organized in a logical way.
The following information should be included in the practical file:
- The name of the experiment or activity
- The date on which the experiment or activity was performed
- The aim of the experiment or activity
- A brief description of the procedure
- The observations and results
- Any calculations that were performed
- A conclusion
The practical file is an important part of the CBSE Class 12 Physics Practical syllabus. It is a way for students to document their work and to demonstrate their understanding of the concepts of physics.
In addition to the practical file, students are also required to answer viva questions on the experiments and activities they have performed. The viva questions are designed to test students’ understanding of the theoretical concepts behind the experiments and activities.
The viva questions are usually asked by the teacher who is conducting the practical exam. However, students can also prepare for the viva questions by reading the theory behind the experiments and activities.
The CBSE Class 12 Physics Practical syllabus is an important part of the overall syllabus for the subject. By carefully planning and executing the experiments and activities, and by preparing for the viva questions, students can make sure that they are well-prepared for the practical exam.
Here are some additional tips for writing a good physics practical file:
- Use clear and concise language.
- Avoid jargon and technical terms.
- Be as accurate as possible in your observations and results.
- Show all of your calculations.
- Draw a neat and labeled diagram of the apparatus used in the experiment.
- Write a clear and concise conclusion.
By following these tips, you can write a physics practical file that is informative, accurate, and easy to understand.
