CBSE Class 10 Science Syllabus 2023 for Practical Exam 

The students must prepare for the science practical exams as well from the CBSE class 10 science syllabus 2022-23. The practicals are as important as the theory exam. The practicals help a candidate to score well because of which the students should thoroughly prepare for the same from the given syllabus.

List of experiments 

Below, we have listed the experiments for each unit which must be practiced by a student:

UNIT 1 experiments

   • Dilute Hydrochloric Acid
   • Dilute NaOH solution
   • Dilute Ethanoic Acid solution
   • Lemon juice
   • Water
   • Dilute Hydrogen Carbonate solution

B. Studying the properties of acids and bases (HCl & NaOH) on the basis of their reaction with

• Litmus solution (Blue/Red)
• Zinc metal
• Solid sodium carbonate

2. Performing and observing the following reactions and classifying them into

• Combination reaction
• Decomposition reaction
• Displacement reaction
• Double displacement reaction
• (i) Action of water on quicklime (ii) Action of heat on ferrous sulphate crystals (iii) Iron nails kept in copper sulphate solution (iv) Reaction between sodium sulphate and barium chloride solutions.

3. Observing the action of Zn, Fe, Cu and Al metals on the following salt solutions:

• ZnSO4(aq)
• FeSO4(aq)
• CuSO4(aq)
• Al2 (SO4)3(aq)

Arranging Zn, Fe, Cu and Al (metals) in the decreasing order of reactivity based on the above result.

4. Study of the following properties of acetic acid (ethanoic acid):

• Odour
• solubility in water
• effect on litmus
• reaction with Sodium Hydrogen Carbonate

5. Study of the comparative cleaning capacity of a sample of soap in soft and hard water.

UNIT 2:

1. Preparing a temporary mount of a leaf peel to show stomata.
2. Experimentally show that carbon dioxide is given out during respiration.
3. Identification of the different parts of an embryo of a dicot seed (peas, gram or red kidney bean).
4. Studying (a) binary fission in Amoeba, and (b) budding in yeast and Hydra with the help of prepared slides.

UNIT 3:

2. Determination of the focal length of

• Concave mirror
• Convex lens by obtaining the image of a distant object.

3. Tracing the path of a ray of light passing through a rectangular glass slab for different angles of incidence. Measure the angle of incidence, angle of refraction, and angle of emergence and interpret the result.

UNIT 4:

1. Studying the dependence of potential difference (V) across a resistor on the current (I) passing through it and determining its resistance. Also plotting a graph between V and I.
2. Determination of the equivalent resistance of two resistors when connected in series and parallel.
