Class 10 Science Syllabus 2023-24

  Class 10 Science Syllabus 2023-24

Hello doston,

I am back with my new blog today I am going to share the latest  Class 10 Science Syllabus 2023-24.

It's the official syllabus by CBSE so that you can continue your studies with the right syllabus. There is not much change in the syllabus with respect to the 2023 session, only some of the chapters and topics are deleted. The syllabus is divided into 5 units: Chemical Substances-Nature and Behaviour,  World of Living,  Natural Phenomena,  Effects of Current,  Natural Resources. The syllabus also includes the practicals that total 14. This syllabus also includes the criteria on which marks will be given to you.

You will get 20 marks from internal assessment and 80 marks for your board's paper. the direct download link of the  Class 10 Science Syllabus 2023-24 is given below just download it in one click and if you don't want to download the file you can see the syllabus on this page also.

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 carryingconductor, 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.

Unit V: Natural Resources

Our environment: Eco-system, Environmental problems, Ozone depletion, waste production and

their solutions. Biodegradable and non-biodegradable substances.

Note for the Teachers:

1. The chapter Management of Natural Resources (NCERT Chapter 16) will not be assessed

in the year-end examination. However, learners may be assigned to read this chapter and

encouraged to prepare a brief write up to any concept of this chapter in their Portfolio. This

may be for Internal Assessment and credit may be given Periodic Assessment/Portfolio).

2. The NCERT text books present information in boxes across the book. These help students

to get conceptual clarity. However, the information in these boxes would not be assessed

in the year-end examination.

PRACTICALS

Practical should be conducted alongside the concepts taught in theory classes.
