Science Practical Class 10

The Central Board of Secondary Education provides a well-structured syllabus for the practical examinations. The science practical class 10 consist of experiments that are interesting and related to the syllabus. These experiments introduce students to different instruments and devices that are used for measurements like measurement of diameter, thickness, understanding the acidic and basic nature of chemicals, etc.

The science practical class 10 have two sections: section A where the experiments are carried out and the observations are recorded. Section B where viva questions are been asked based on the experiments conducted by the student.

Class 10 Science Experiments

Experiment 2

Studying the properties of acids and bases (HCl & NaOH) by their reaction with:

  • Litmus solution (Blue/Red)
  • Zinc metal
  • Solid sodium carbonate
Experiment 3

Performing and observing the following reactions and classifying them into:

  • Combination reaction
  • Decomposition reaction
  • Displacement reaction
  • Double displacement reaction
    • Action of water on quick lime
    • Action of heat on ferrous sulphate crystals 70
    • Iron nails kept in copper sulphate solution
    • Reaction between sodium sulphate and barium chloride solutions
Experiment 4

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

Experiment 6

Determination of the equivalent resistance of two resistors when connected in series and parallel.

Experiment 7

Preparing a temporary mount of a leaf peel to show stomata.

Experiment 8

Experiment 9

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

  • odour
  • solubility in water
  • effect on litmus
  • reaction with sodium Hydrogen Carbonate
Experiment 10

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

Experiment 11

Determination of the focal length of:

  • Concave mirror
  • Convex lens by obtaining the image of a distant object.
Experiment 12

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, angle of emergence and interpret the result.

Experiment 13
