More suggested Projects

• Checking the bacterial contamination in drinking water by testing sulphideion
• Study of the methods of purification of water
• Testing the hardness, presence of Iron, Fluoride, Chloride, etc., depending upon the
regional variation in drinking water and study of causes of presence of these ions above
permissible limit (ifany).
• Investigation of the foaming capacity of different washing soaps and the effect of addition
of Sodium carbonate on it
• Study the acidity of different samples of tealeaves.
• Determination of the rate of evaporation of different liquids
• Study the effect of acids and bases on the tensile strength offibers.
• Study of acidity of fruit and vegetable juices.

Note: Any other investigatory project, which involves about 10 periods of work, can be chosen with the approval of the teacher.
