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).
12. 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 the 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:

Worksheets have become a driving force in today's CBSE curriculum in India. All the CBSE Schools in India use worksheets for the purposes of supporting studying, promoting active learning, raising interest in learning science, and assessment.Worksheets are very much useful in a number of ways in terms of academic achievement. For instance as supplements to NCERT and reference textbooks, worksheets are often used to add additional information for any particular class. Also on top of that, leaving blanks in worksheets are invitations for students to fill in gaps which act as an opportunity for knowledge construction. Well drafted questions and exercises in worksheets helps in drawing students interest. Furthermore, worksheets play a variety of functions in different contexts.
With the help of an effective and elaborative worksheet, students are able to understand how to attempt certain problems and solve them independently. Classroom studies are good, but as a student it is very imperative to know how much of the teachings has been grasped by the student, which can be tested only with the help of worksheets. If a student is unable to solve the worksheet in full it clearly indicates that he or she has missed some portion that was taught in the class and hence all those doubts can be cleared and moved forward without any backlog.
CBSE recommends that the best use of efficient worksheets is that they should be given as a part of home assignment and should includeeverything that was taught in the classroom. Giving out constructive worksheets as homework is an amazing way for the students to recap what they have learned once they are home, as well as a good way for the teachers to reiterate the concept they are trying to teach.
Worksheets are also an effective measurement tool for parents to gauge what their child has been taught in the school. Once they go through the content of the worksheet they understand what all points have been covered in the class and thereby they can take lead and engage their kids in better understanding and revision of the topics.
Worksheets give a fun approach in learning and it has been proven that with worksheets students tend to feel more involved and thus show interest in studies and grasping new things. It is this highly emphasised that worksheets should be designed in such a manner that students find the interest in solving and understand the fundamental concepts easily.
