Class 9 Science Experiments List

Practical exercises should be conducted alongside the concepts taught in theory classes.

A. (Unit I Chapter 2)

Preparation of:

1. a true solution of common salt, sugar and alum
2. a suspension of soil, chalk powder and fine sand in water
3. a colloidal solution of starch in water and egg albumin/milk in water and distinguish between these on the basis of

• transparency
• filtration criterion
• stability

B. (Unit I Chapter 2)

‍Preparation of

1. A mixture
2. A compound using iron filings and sulphur powder and distinguishing between these on the basis of:

• behaviour towards a magnet
• behaviour towards carbon disulphide as a solvent
• effect of heat

C. (Unit I Chapter 2)

Perform the following reactions and classify them as physical or chemical changes

1. Iron with copper sulphate solution in water
2. Burning of magnesium ribbon in air
