CBSE Class 9 Science Practicals?

Introduction

Practicals are equally important as the theory subject. By performing the practicals, students learn by actual participation, which lasts for a longer time duration. Generally, most students forget the concepts that they have learned in the theory classes. But, when they perform the Science practicals, they remember it for a longer period of time. We easily forget the things that we listen to, but what we see remains firm in our memory. CBSE has therefore introduced practicals for Science subjects in class 9. Here we have provided all the details of CBSE class 9 Science practicals for students.

Science practicals not only help students to understand the concepts but also generate interest among them. They get a platform where they can try out different things and showcase their creativity. In this way, the love of Science also gets enhanced among them. Students who find Science as difficult also begin taking an interest in the subject.

CBSE Class 9 Science Practicals – Syllabus, Lab Manual and Kit

CBSE has provided the official syllabus for class 9 Science practicals. Board has allocated 30 periods for conducting all the practicals. Here we have provided a list of Science experiments that students need to perform in the laboratory. Further, we have also provided the information on the lab manual, important questions asked in practical exams and NCERT science manual kit.

CBSE Class 9 Science Practicals Syllabus – List of Experiments

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) Effects of heat

3) Separation of the components of a mixture of sand, common salt and ammonium chloride (or camphor).

4) 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

5) Preparation of stained temporary mounts of

(a) Onion peel

(b) Human cheek cells

To record observations and draw their labeled diagrams

6) 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.

7) Determination of the melting point of ice and the boiling point of water.

8) Verification of the Laws of reflection of sound.

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

10) Establishing the relation between the losses 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

11) Determination of the speed of a pulse propagated through a stretched string/slinky (helical spring).

12) Study of the characteristics of Spirogyra, Agaricus, Moss, Fern, Pinus (either with male or female cone) and an Angiosperm plant. Draw and give two identifying features of groups they belong to.

13) Observe the given pictures/charts/models of earthworm, cockroach, bony fish and bird. For each organism, draw their picture and record:

a) One specific feature of its phylum

b) One adaptive feature with reference to its habitat

14) Verification of the law of conservation of mass in a chemical reaction.

15) Study of the external features of root, stem, leaf and flower of monocot and dicot plants.
