, PREFACE
Kendriya Vidyalayas are the pioneer institutions in the field of Education
focusing all round development of the students. Keeping in view of the
implementation of CCE it is desired to prepare study/ support material for
Class IX to guide the students in the right direction and to equip the students to
face the challenges with ease.
The purpose of this Study Material is to help learners study more effectively
and efficiently. It is designed to help increase the retention of what they are
studying for the purpose of using it more successfully at a later time—while
taking a test.
For the academic year 2012-13 the task has been allotted to Kendriya
Vidyalaya Sangathan ZONAL INSTITUTE OF EDUCATION & TRAINING,
CHANDIGARH for preparation of study/ support material for Class IX Science.
Kendriya Vidyalaya Sangathan ZONAL INSTITUTE OF EDUCATION &
TRAINING, CHANDIGARH records appreciation for the sincere efforts of Mrs.
Medha U (PGT Physics), Ms. Ameeta Kumari (PGT Chemistry) & Mr. G.
varaprasad (PGT Biology) of this institution for preparing the study material.
The development of content is based on the detailed survey feed back taken
from the students on all the concepts from each unit. I am confident that the
study/ support material will definitely help the students to understand the
concepts well and meet quality expectations.
