It gives me great pleasure to bring out Biology Lab Manual for class IX students. This carefully planned manual for class IX has been prepared strictly in accordance with the syllabus for ICSE practical examination. It is profusely illustrated and precisely written in a simple lucid language, covering all essential facts. The manual carries useful information on planning, and performing experiments and key points which are required in the description of apparatus are very much useful in the examination. At the end of each chapter, there are some commonly asked questions pertaining to laboratory work along with their answers.
