CBSE Class 9 Science Syllabus 2022-23 Practical Exams

Below is the list of experiments prescribed by CBSE for Class 9 Science:

1. Preparation of

• a true solution of common salt, sugar, and alum
• a suspension of soil, chalk powder, and fine sand in water
• a colloidal solution of starch in water and egg albumin/milk in water and distinguish between these based on
  • Transparency
  • filtration criterion
  • stability

2. Preparation of

• A mixture
• A compound

Using iron filings and sulphur powder and distinguishing between these based on:

• appearance, i.e., homogeneity and heterogeneity
• behaviour towards a magnet
• behaviour towards carbon disulfide as a solvent
• effect 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:

• Iron with copper sulphate solution in water
• Burning of magnesium ribbon in air
• Zinc with dilute sulphuric acid
• Heating of copper sulphate crystals
• Sodium sulphate with barium chloride in the form of their solutions in water

5. Preparation of stained temporary mounts of 

• onion peel
• 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 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 loss in weight of a solid when fully immersed in

• Tap water
• 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).

Importance of Question Bank for Exam Preparation?

There are many ways to ascertain whether a student has understood the important points and topics of a particular chapter and is he or she well prepared for exams and tests of that particular chapter. Apart from reference books and notes, Question Banks are very effective study materials for exam preparation. When a student tries to attempt and solve all the important questions of any particular subject , it becomes very easy to gauge how much well the topics have been understood and what kind of questions are asked in exams related to that chapter.. Some of the other advantaging factors of Question Banks are as follows

1. Since Important questions included in question bank are collections of questions that were asked in previous exams and tests thus when a student tries to attempt them they get a complete idea about what type of questions are usually asked and whether they have learned the topics well enough. This gives them an edge to prepare well for the exam.Students get the clear idea whether the questions framed from any particular chapter are mostly either short or long answer type questions or multiple choice based and also marks weightage of any particular chapter in final exams.
2. CBSE Question Banks are great tools to help in analysis for Exams. As it has a collection of important questions that were asked previously in exams thereby it covers every question from most of the important topics. Thus solving questions from the question bank helps students in analysing their preparation levels for the exam. However the practice should be done in a way that first the set of questions on any particular chapter are solved and then solutions should be consulted to get an analysis of their strong and weak points. This ensures that they are more clear about what to answer and what can be avoided on the day of the exam.
3. Solving a lot of different types of important questions gives students a clear idea of what are the main important topics of any particular chapter that needs to focussed on from examination perspective and should be emphasised on for revision before attempting the final paper. So attempting most frequently asked questions and important questions helps students to prepare well for almost everything in that subject.
4. Although students cover up all the chapters included in the course syllabus by the end of the session, sometimes revision becomes a time consuming and difficult process. Thus, practicing important questions from Question Bank allows students to check the preparation status of each and every small topic in a chapter. Doing that ensures quick and easy insight into all the important questions and topics in each and every individual. Solving the important questions also acts as the revision process.
