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 X to guide the students in the right direction and to equip the students to face the challenges with ease.

For the academic year 2011-12 the task has been allotted to Kendriya Vidyalaya Sangathan, Mumbai Region for preparation of

study/support material in Class X-Science.

Kendriya Vidyalaya Sangathan, Mumbai Region records appreciation for the sincere efforts of Mrs. Geetha B., Principal, KV-No.3 Colaba, Mumbai and Mrs. Savitri T., Principal, KV-CME Pune and the team of dedicated and committed teachers – Mrs. T. Virdi & Mrs. A. Ponkshe, KV-CME Pune, Mrs. Swathi Kulkarni & Mr. AK Rai, KVNo.3 Colaba for preparing the study material.

I am confident that the support/study material will definitely help the students to understand the concepts well and meet quality expectations.
