CBSE Class 9 Revised Science Practical Syllabus

Practicals are also important along with the theory concepts. So, here we have provided the CBSE Syllabus for Class 9 Science Practicals. The list of experiment are being listed below. The CBSE Class 9 Science Lab Manual will help students in performing the experiment and guide them how to do the experiments.

List of Experiments – CBSE Syllabus for Class 9 Revised Science Practicals

1. Preparation of:

a) a true solution of common salt, sugar and alum

b) a suspension of soil, chalk powder and fine sand in water

c) a colloidal solution of starch in water and egg albumin/milk in water and distinguish between these on the basis of
