    CBSE Class 9 Science Practical Exam: Syllabus and Preparation Tips

    Generally, students pay less attention towards practicals as they think them to be of little importance when considered for annual grades. But they should understand the fact that practicals play an important role in the learning process. Practicals are conducted to engage students, helping them to develop important skills and understand scientific concepts.

    When it comes to the grades, marks scored in practical exam are added to the marks obtained in theory paper which can help students earn some extra percentage or grades in aggregate.

    CBSE Class 9 Exam Pattern 2017-2018

    So, students must be serious while preparing for the practical exams.

    Viewing the importance of practical exams, jagranjosh brings here the revised syllabus for the CBSE Class 9 Science Practical Exam 2018 along with some important preparation tips to perform well in the exam.

    CBSE Class 9 Science Practical Syllabus:

    List of Experiments

    Experiment 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 distinction between these on the basis of

    • transparency
    • filtration criterion
    • stability

    Experiment 2. Preparation of

    a) a mixture

    b) a compound

    using iron filings and sulphur powder and distinction 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

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

    Experiment 4. Performing the following reactions and classifying 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.

    Experiment 5. Preparation of stained temporary mounts of (a) onion peel, (b) human cheek cells & to record observations and draw their labeled diagrams.

    Experiment 6. Identification of Parenchyma, Collenchyma and Sclerenchyma tissues in plants, striped, smooth and cardiac muscle fibers and nerve cells in animals from prepared slides. Drawing of their labeled diagrams.

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

    Experiment 8. Verification of the Laws of reflection of sound.

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

    Experiment 10. 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.

    Experiment 11. Determination of the speed of a pulse propagated through a stretched string / slinky.

    Experiment 12. Study of the characteristics of Spirogyra / Agaricus, Moss / Fern, Pinus (either with male or female cone) and an Angiospermic plant. Drawing and providing two identifying features of the groups they belong to.

    Experiment 13. Observing the given pictures / charts / models of earthworm, cockroach, bony fish and bird. For each organism, drawing of their picture and recording :

    a) one specific feature of its phylum.

    b) one adaptive feature with reference to its habitat.

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

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

    Preparation Tips for Class 9 Science Practical Exams 2018

    • Read each experiment carefully to understand the principle working behind it.
    •  Study the theory behind the experiment thoroughly
    • Understand the basics of the experiment, as examiner may ask you the principles and methodology of that experiment during viva voice.
    • Learn the step-wise procedure to conduct each experiment properly.
    • Never try to cram the readings as different apparatus have different specifications which may cause an alteration in the readings obtained for an experiment at different times.
    • Learn the circuits and diagrams properly wherever required.
    • Learn to distinguish various compounds by their colour, smell or odour.
