General Instructions:-There will be an Annual Examination based on the entire syllabus.The Annual Examination will be of 80 marks and 20 marks weightage shall be for Internal Assessment.
For Internal Assessment:
a. There will be Periodic Assessment that would include:
For 5 marks– 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.
For 5 marks– Diverse methods of assessment as per the need of theclass 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
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

Unit IV: Food Production
Plant and animal breeding and selection for quality improvement and management; Use of fertilizers and manures; Protection from pests and diseases; Organic farming.
Note for the Teachers:
- The chapter Natural Resources (NCERT Chapter 14) 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 on any concept of this chapter in their Portfolio. This may be for
Internal Assessment and credit may be given for Periodic Assessment/Portfolio. - 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.
