Knowledge of Practical Science and its implementation is taught to the students of class 10th through experiments. The main objective of learning Practical Science is to familiarise students with the various kinds of experiments being performed in the laboratories and the different tools required.  

Students will clearly understand the concepts when performing experiments as they will visually observe the changes during experimental activities. 

NCERT Science practical book for class 10th is divided into four major units. Students can check and download the unit-wise CBSE Class 10th Science practical book PDF files below in the following table.

   • 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:

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 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 CBSE class 10 Science practical 2025 can refer to the below tips to score top marks. However, they must download the CBSE Class 10th Science practical book before that.

• Students must fully understand the objectives, process and note the observations of every experiment, this will solidify their concepts.
• Students must maintain detailed record 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.
• Additionally, students must prepare for the Viva Voce round, by practising the suggested questions, as it will help them perform better.
