PRACTICALS (Selected)
Class - 9
List of experiments

1. To prepare
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 of starch in water and egg albumin in water and distinguish between these on the
basis of
i) transparency
ii) filtration criterion
iii) stability

2. To prepare
a) a mixture
b) a compound
using iron filings and sulphur powder and distinguish between these on the basis of:
i) appearance i.e., homogeneity and heterogeneity
ii) behaviour towards a magnet
iii) behaviour towards carbon disulphide a solvant.
iv) effect of heat.

3. To study the extent of cooling caused by evaporation on the following liquids, using a
thermometer. Also to arrange these liquids in the increasing order of the extent of
cooling produced
i) Water
ii) Alcohol
iii) Ether

4. To determine the density of solid (denser than water) by using a spring balance and a
measuring cylinder.

5. To establish the relation between the loss in weight of a solid when fully immersed in
i) tap water
ii) strongly salty water, with the weight of water displaced by it by taking at least two
different solids.

6. To measure the temperature of hot water as it cools and plot a temperature-time graph.

7. To prepare stained temporary mounts of (a) onion peel and (b) human cheek cells and to record
observations and draw their labelled diagrams.
