CBSE Class 10 Science Syllabus 2023-2024: The CBSE syllabus of Class 10 Science for the new academic session 2023-24 has been released. The new CBSE Class 10 Science Syllabus is divided into five broad themes viz. Materials, The World of The Living, How Things Work, Natural Phenomenon and Natural Resources. You can check the contents and download the complete syllabus of CBSE Class 10 Science from this article.

General instructions to be noted for CBSE Class 10 Science Curriculum 2023-24 are:

1.There will be an Annual Examination based on the entire syllabus.

2. The Annual Examination will be of 80 marks and 20 marks weightage shall be for Internal Assessment.

3. For Internal Assessment:

a. There will be Periodic Assessment that would include:

  • Three periodic tests conducted by the school. Average of the best two tests to be taken that will have a weightage of 05 marks towards the final result.
  • Diverse methods of assessment as per the need of the class dynamics and curriculum transaction. These may include – short tests, oral test, quiz, concept maps, projects, posters, presentations and enquiry based scientific investigations etc. and use rubrics for arguing them objectively. This will also have a weightage of 05 marks towards the final result.

b. Practical / Laboratory work should be done throughout the year and the student should maintain record of the same. Practical Assessment should be continuous. There will be weightage of 5 marks towards the final result. All practicals listed in the syllabus must be completed.

c. Portfolio to be prepared by the student- This would include classwork and other sample of student work and will carry a weightage of 5 marks towards the final results.

Theme: How Things Work

Unit 4: Effects of Current

Electricity: Electric current, potential difference and electric current. Ohm’s law; Resistance, Resistivity, Factors on which the resistance of a conductor depends. Series combination of resistors, parallel combination of resistors and its applications in daily life. Heating effect of electric current and its applications in daily life. Electric power, Interrelation between P, V, I and R.

Magnetic effects of current: Magnetic field, field lines, field due to a current carrying conductor, field due to current carrying coil or solenoid; Force on current carrying conductor, Fleming’s Left Hand Rule, Direct current. Alternating current: frequency of AC. Advantage of AC over DC. Domestic electric circuits.

Theme: Natural Resources

Unit 5: Natural Resources
