The CBSE Class 10 Science Syllabus for the academic year 2025-26 is structured to help students build a strong foundation in Physics, Chemistry, and Biology. It has been carefully planned by NCERT and CBSE to balance theoretical understanding and practical application. The syllabus not only helps students score well in board exams but also prepares them for future competitive exams like NEET, JEE, and Olympiads.
From learning how chemical reactions take place, to understanding the human body, electric circuits, and environmental conservation, the CBSE Class 10 Science Syllabus takes students through a journey of real world science. The subject encourages observation, experimentation, and logical thinking, all while developing a curiosity for how the world works.
Students are advised to follow the NCERT Class 10 Science textbook strictly, as questions in the exam will be directly based on this content. Internal assessments and practical work are also part of the curriculum, making hands-on learning a crucial part of the syllabus.
