The Science subject helps students to understand the world around us. It inculcate the creativity and curiosity to learn new things among the students. The topics like crop production, metal and non metal, reproduction in animals, sound, pollution etc are introduced to students in CBSE Class 8 Science. According to my teaching experience, It is very important for students to perform well in Class 8 because of various reasons. Firstly, the syllabus of Class 9 and Class 10 Science is very closely related to that of the CBSE syllabus of Class 8 Science. So, if you do not understand the concepts properly now, you will face difficulty later. Second, if you are planning to appear for competitive exams in the future, like UPSC Civil Services Examination, NTSE and Olympiads, you have to be prepared to face higher level questions which need a clear understanding of the basics and a very strong foundation. This means every single concept in the CBSE syllabus of Class 8 Science must be finished thoroughly.
