Activities to be Written in CBSE Class 9 Science Lab Manuals

Students can conduct the experiments listed below in their CBSE 9th science lab. The other experiments are available in the PDF file provided above.

Activity 9.1.1 How will you show and compare the compressibility of gases and liquids?

What is required?

Syringe (2mL), water and beaker

How will you proceed?

• Take a clean syringe and pull the piston outward [Fig. 9.1.1 (a) i].

• Block the nozzle of the syringe with your thumb [Fig. 9.1.1 (a) ii] and push the piston inward. Release the piston and record its position.

• Push the piston inward again and release it. Does it come back to its original position? [Fig.9.1.1 (a) iii]

• Repeat the above experiment by filling the syringe with water and note the observations [Fig.9.1.1 (b)].

Activity 9.1.3 How will you study the phenomenon of sublimation?

What is required?

Camphor / naphthalene / iodine, tripod, China dish, funnel, cotton, kerosene burner and spatula

How will you proceed?

Take a spatula full of crushed camphor / naphthalene / iodine in a clean and dry China dish and place it on the tripod.

2. Take a funnel and plug its nozzle with of cotton.

3. Invert this funnel on the China dish.

4. Light the kerosene burner and place it under tripod.

5. Heat the China dish for a few minutes and observe what happens.

6. Has a camphor / naphthalene / iodine change into the liquid state?

What have you learnt?

1. On the inner wall of the funnel, solid deposit of camphor/ naphthalene/iodine was observed.

2. Solid camphor / naphthalene / iodine on heating changed from solid state directly to vapour state. This process is known as sublimation.

Marks Distribution of CBSE 9th Practical Examination

CBSE 9th science internal assessment is a key part of 9th Class, with a total of 20 marks dedicated to it. This CBSE has divided it into three main categories:

1. Periodic Assessment (10 marks)

This component is designed to measure consistent academic progress throughout the year. It includes:

• Periodic Tests (5 marks): School will conduct three periodic tests. The average best two scores from these tests will be used to calculate a weightage of 5 marks toward final CBSE result.

• Diverse Assessment Methods (5 marks): Teachers will use various methods beyond traditional tests to test students understanding. These may include short quizzes, oral tests, group projects, posters, presentations, and inquiry-based scientific investigations. They will contribute 5 marks to final score.

2. Practical/Laboratory Work (5 marks)

This part focuses the practical and laboratory work that students. This component is worth 5 marks.

3. Portfolio (5 marks)

It is a collection of work, including classwork and other student work samples. This may include the practical file, class notebook or other assignments provided by the teachers.
