CBSE Class 9 Science Practicals

Practicals are equally important as the theory subject. By performing the practicals, students learn by actual participation, which lasts in their memory 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 firmly etched 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. Moreover, students who find Science to be 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) Effect of heat

3) Separation of the components of a mixture of sand, common salt and ammonium chloride (or camphor).      (not included for this academic year)

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 labelled diagrams

6) Identification of Parenchyma, collenchyma and Sclerenchyma tissues in plants, striped, smooth and cardiac muscle fibres and nerve cells in animals, from prepared slides. Draw their labelled diagrams.

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

8) Establishing the relation 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

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

10) Determination of the speed of a pulse propagated through a stretched string/slinky (helical spring). (not included for the academic year)

11) Study of the characteristics of Spirogyra, Agaricus, Moss, Fern, Pinus (either with male or female cone) and an Angiospermic plant. Draw and give two identifying features of groups they belong to. (not included for the academic year)

12) Observe the given pictures/charts/models of earthworm, cockroach, bony fish and bird. For each organism, draw their picture and record:    (not included for the academic year)

a) One specific feature of its phylum

b) One adaptive feature with reference to its habitat

13) Verification of the law of conservation of mass in a chemical reaction. (not included for academic year)

14) Study of the external features of root, stem, leaf and flower of monocot and dicot plants. (not included for academic year)

CBSE Class 9 Science Laboratory Manuals

Students performing experiments by themselves is a thrilling experience as they learn by participating. All the experiments are performed in the school Science laboratory. So, students must be aware of certain rules and regulations before performing experiments in the laboratory. For this purpose, the CBSE class 9 Science lab manual has been provided by the board. The laboratory manual familiarises students with the general facilities, chemical and glassware, measuring instruments, equipment, specimen available in a school Science laboratory. The lab manual also mentions the precautions and safety measures mandatory for students to follow.

The description of the experiment in CBSE Class 9 Science laboratory manual is provided in the following format:

1. Aim of the experiment.
2. Theory or the principle involved in the experiment.
3. List of materials required to perform the experiment.
4. Steps to be followed while performing the experiment.
5. Recording the observations.
6. The formula required for calculations and finally recording the result of the experiment.

CBSE Class 9 Science Practical Important Questions

Here we have listed a few questions from the CBSE Class 9 Science manuals. These questions are related to Physics, Chemistry and Biology topics of Science. However, students will get all these questions in the pdf file, which is provided above in the table format. At the end of each experiment, a few questions are provided in the lab manual.

Q1) A 100 g block slides when tension in the string is x N. What will be the tension in the string when an identical block is placed at the top of the first block?

Q2) State the factors on which the buoyant force acting on an object immersed in a fluid depends.

Q3) What will happen if a de-shelled egg is placed in a solution with the same osmotic concentration as in the egg?

Q4) What are the conditions that are helpful for breeding of mosquitoes?

Q5) A metal cylinder is melted and the whole mass is cast in the shape of a cube. What happens to its density? Give reasons.

Q6) What different techniques of separation can be employed for separation of components of homogeneous and heterogeneous mixture?

NCERT Class 9 Science Manual Kit

The NCERT class 9 Science manual kit describes the kit items and their uses. It contains the activities of NCERT class 9 Science textbook. Also, the experiments that are provided can be performed using this kit. The NCERT textbooks are designed in such a way that it covers various activities. In each chapter, topics are explained with the help of activities. Just merely reading through the textbook will not help students to understand these concepts explained. It is required that students perform these activities. This can be done through the NCERT manual of Class 9 Science kit. Performing these activities will enable students to think and explore. This will inculcate the questioning ability, exploring and discovering, which will create interest towards scientific discovery in students.

Each activity in the NCERT class 9 Science manual kit is explained through the following points:

1. The materials and instruments required to perform the activity.
2. Steps to perform the activity.
3. The outcome of the activity that students have learned from it.
