Note for the Teachers: 
 
1. 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. 
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 
Practicals should be conducted alongside the concepts taught in theory classes.

1. Preparation of: Unit-I 
 
a) a true solution of common salt, sugar and alum 
 
b) a suspension of soil, chalk powder and fine sand in water
