Class 9 Science Syllabus 2021-22 for Term 1 & 2
Science in class 9 is one of the important subjects which is to be covered in the board examinations. The basic concepts in class 9 science syllabus will help in building up the advance concepts in further classes. There is no further subdivision of Science into Physics, chemistry and biology, the basic concepts have been incorporated in the subject. The syllabus also covers experiments which are required for the practical classes. The marks distributed according to the units are as follows:
|CBSE Class 9 Syllabus: Unit-wise Marks Distribution|
|Unit 1: Matter – Its Nature And Behavior||23|
|Unit 2: Organisation In The Living world||20|
|Unit 3: Motion, Force, And Work||27|
|Unit 4: Our Environment||06|
|Unit 5: Food Production||04|
Out of the 100 marks, the remaining 20 marks are covered by the internal assessment which are undertaken by the practical exams.
Internal Assessment: Throughout the year-irrespective of Term 1 & 2 would include the 3 periodic tests, student enrichment, portfolio and practical work/ speaking listening activities/ project.
