CBSE Class 9 Science Practical and Experiments

The students of class 9^th are supposed to do the following experiments in an academic year.

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

• transparency
• filtration criterion
• stability

2. Preparation of
a) A mixture
b) A compound
using iron filings and sulphur powder and distinguishing between these on the basis of:
(i) appearance, i.e., homogeneity and heterogeneity
(ii) behaviour towards a magnet
(iii) behaviour towards carbon disulphide as a solvent
(iv) effect of heat

3. Perform the following reactions and classify them as physical or chemical changes:
a) Iron with copper sulphate solution in water
b) Burning of magnesium ribbon in air
c) Zinc with dilute sulphuric acid
d) Heating of copper sulphate crystals
e) Sodium sulphate with barium chloride in the form of their solutions in water
4. Preparation of stained temporary mounts of (a) onion peel, (b) human cheek cells & to record observations and draw their labeled diagrams.
5. Identification of Parenchyma, Collenchyma and Sclerenchyma tissues in plants, striped, smooth and cardiac muscle fibers and nerve cells in animals, from prepared slides. Draw their labeled diagrams.
6. Determination of the melting point of ice and the boiling point of water.
7. Verification of the Laws of reflection of sound.
8. Determination of the density of solid (denser than water) by using a spring balance and a measuring cylinder.
9. Establishing the relation between the loss in weight of a solid when fully immersed in
a) Tap water
b) Strongly salty water with the weight of water displaced by it by taking at least two different solids.
10. Determination of the speed of a pulse propagated through a stretched string/slinky (helical spring).
11. Verification of the law of conservation of mass in a chemical reaction.
