Class 9th science of practicals
List of Experiments for Term I
Perform and classify the following reactions as physical or chemical changes:
- Iron with copper sulfate solution in water
- Burning of magnesium ribbon in air
- Zinc with dilute sulphuric acid
- Heating of copper sulfate crystals
- Sodium sulfate with barium chloride in the form of their solutions in water
- A mixture
- A compound
Using iron filings and sulfur powder and distinguish these on the basis of:
(i) appearance, i.e., homogeneity and heterogeneity
(ii) behavior with a magnet
(iii) behavior with a carbon disulfide as a solvent
(iv) effect of heat
a) a true solution of common salt, alum, and sugar
b) a suspension of soil, fine sand in water, and chalk powder.
c) a colloidal solution of starch in water & egg albumin/milk in water & differentiate in between on the basis of
- filtration criterion
Identify Parenchyma, collenchyma & Sclerenchyma tissues in plants, striped, smooth, & cardiac muscle fibers & nerve cells in animals, from prepared slides. Draw labeled diagrams.
Preparation of stained temporary mounts of
(a) onion peel,
(b) human cheek cells, and recording observations and drawing their labeled diagrams.
List of Experiments for Term II
- Verify the law of conservation of mass in a chemical reaction.
- Determine the density of solid by using a spring balance and a measuring cylinder.
- Establish the relationship 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.
