List of Experiments in CBSE Class 10 Science Practical Book 2025

According to the CBSE 10th Science syllabus 2024-25, the experiments listed in the CBSE Class 10th Science practical book 2025 are divided into two terms. Knowledge of Practical Science and its implementation is taught to the students of class 10th through experiments. 

The term-wise experiments and their details are listed below:

Term 1:

Experiment 1: 

1. To find the pH of the below-given samples using universal indicator/ pH paper.

   • Water 

   • Dilute Hydrogen Carbonate solution 

   • Dilute Ethanoic Acid solution

   • Lemon juice

   • Dilute Hydrochloric Acid

   • Dilute NaOH solution

2. To study the properties of Acids and Bases on the basis of their reaction with the following:

   • Solid sodium carbonate

   • Zinc metal

   • Litmus solution (Blue or Red)

Experiment 2:

1. To perform and observe the following reactions:

   • Decomposition reaction

   • Double displacement reaction

   • Displacement reaction

   • Combination reaction

     • Iron nails kept in copper sulphate solution

     • Action of heat on ferrous sulphate crystals

     • Reaction between sodium sulphate and barium chloride solutions

     • Action of water on quicklime

Experiment 3:

• To observe the action of aluminium, zinc, copper and iron metals on the below-given solutions.

  • FeSO₄(aq)

  • Al₂ (SO4)₃(aq)

  • CuSO₄(aq)

  • ZnSO₄(aq)

Based on the above results, all the metals should be arranged in decreasing order of reactivity.

Experiment 4:

To experimentally show that carbon dioxide is given out during respiration.

Experiment 5:

To determine the focal length of the following by obtaining distant images:

• Convex lens

• Concave mirror

Experiment 6:

To trace the path of a ray of light passing through a rectangular glass slab, for different angles of incidence. To measure the angle of incidence, angle of refraction, angle of emergence, and interpret the result.

Experiment 7:

To trace the path of the rays of light through a glass prism.

Term 2:

Experiment 1:

To study the dependence of potential differences across a resistor on the current passing through it and to determine its resistance. The graph between the potential difference and current should also be plotted.

Experiment 2:

Study the following with the help of prepared slides:

• Binary fission in Amoeba
• Budding in yeast and Hydra

Viva Questions For CBSE Class 10th Science Practical

Once students complete the experiment, there will be a few questions which may be asked during the Viva round. These questions aim to determine the student's knowledge of that particular experiment.

Candidates can practice the CBSE Class 10 Question Bank in detail to get the necessary details regarding the question pattern and marking scheme. Below are a few questions which can be asked for CBSE Class 10th Science Practical.

1. How are the magnetic field lines of a straight current-carrying wire different from the field lines of a bar magnet?
2. On what factors does the refractive index of a medium depend?
3. Why is it advised to clean the ends of connecting wires before connecting them?
4. Why are the incident and emergent rays parallel to each other in the case of a rectangular glass slab?
5. How does the carbon dioxide gas enter the leaves?
6. Which by-product of fermentation is useful in the brewing industry?
7. Why is sulphur dioxide collected by the upward displacement of air?
8. What is your observation when copper is added to iron (II) sulphate solution?

How to Prepare From CBSE Class 10 Science Practical Book?

Candidates gearing up for the upcoming exam can refer to the below tips while going through the CBSE class 10 preparation to score top marks. However, they must download the CBSE Class 10th Science practical book before that.

The pointers below show the essential ways to prepare for the exam with CBSE class 10 Science practical book 2025.

• Students must fully understand the objectives, and process and note the observations of every experiment, this will solidify their concepts.
• Students must maintain detailed records of the observations they are conducting for analysis purposes and to draw conclusions. 
• Candidates must spend time in developing their problem-solving and analytical skills by studying the observations and data collected through the experiments.
