Force and Newton’s laws: Force and Motion, Newton’s Laws of Motion, Action and reaction forces, Inertia of a body, Inertia and mass, Momentum, Force and Acceleration. Elementary idea of conservation of Momentum.

Gravitation: Gravitation; Universal Law of Gravitation, Force of Gravitation of the earth (gravity), Acceleration due to Gravity; Mass and Weight; Free fall.

Work, energy and power: Work done by a Force, Energy, Power; Kinetic and potential energy; Law of conservation of energy.

ONLY FOR INTERNAL ASSESSMENT

Note: Learners are assigned to read the below listed part of Unit IV. They can be encouraged to prepare a brief write up on any one concept of this Unit in their Portfolio. This may be an assessment for Internal Assessment and credit may be given (Periodic assessment/Portfolio). This portion of the Unit is not to be assessed in the year-end examination.

Theme: Natural Resources: Balance in Nature

Unit IV: Our Environment

Physical resources: Air, Water, Soil. Air for respiration, for combustion, for moderating temperatures; movements of air and its role in bringing rains across India.

Air, Water and Soil pollution (brief introduction). Holes in ozone layer and the probable damages.

Bio-geo chemical cycles in nature: Water, Oxygen, Carbon and Nitrogen.

PRACTICALS

Praticals should be conducted alongside the concepts taught in theory classes.

List of Experiments

1. Preparation of:  (Unit-I)

(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 distinction between these on the basis of

  • Transparency
  • Filtration criterion
  • Stability

2. Preparation of   (Unit-I)

(a) A mixture

(b) A compound

using iron filings and sulphur powder and distinction between these on the basis of:

  • Appearance, i.e., homogeneity and heterogeneity
  • Behaviour towards a magnet
  • Behaviour towards carbon disulphide as a solvent
  • Effect of heat

3. Perform the following reactions and classifying them as physical or chemical changes:   (Unit-I)

(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.  (Unit-II)

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.  (Unit-II)

6. Determination of the density of solid (denser than water) by using a spring balance and a measuring cylinder.

7. Establishing the relation between the loss in weight of a solid when fully immersed in   (Unit-III)

(a) Tap water

(b) Strongly salty water, with the weight of water displaced by it by taking at least two different solids.

8. Verification of the law of conservation of mass in a chemical reaction.   (Unit-III)

Note: This year, CBSE has not mentioned the question paper design in the new syllabus of CBSE Class 9 Science. However, students may refer to the blueprint released for the previous year's annual examination. Format of the Science question paper CBSE Class 9 Annual Examination 2021 is expected to be more or less similar to that of the previous year.
