As the February 2026 board exam season hits its peak, students across India are shifting their focus from theory to the equally critical internal assessments. For many, the  science practical for class 10 state board answers are the key to securing that perfect 20/20 internal score. Whether you are under the Maharashtra SSC, Telangana State Board, or CBSE, the practical exam is a golden opportunity to boost your overall percentage before the theory papers begin. 

In this guide, we provide the most accurate solutions for your science project book for class 10 and the essential viva questions that examiners frequently ask during the 2026 session.

Why 10th Science Practicals are a “Grade Booster” ?

In the current class 10 science curriculum, practicals are not just about performing experiments; they are about understanding the “Application of Science” in real life. Boards have recently increased the weightage of competency-based questions, which often stem from these very experiments. Completing your science project book for class 10 with precision ensures that you don’t lose silly marks on record-keeping. 

 

High-Weightage 10th Science Practicals Experiments for 2026 

Based on the latest state board and CBSE patterns, here are the core experiments you must master: 

1. Physics: Light and Electricity

Most students struggle with the focal length of concave mirrors and Ohm’s Law. 

Key Task: Tracing the path of light through a glass prism. 

Observation Tip: Ensure your incident and emergent rays are clearly marked with arrows. In the Ohm’s Law experiment, always check that your voltmeter is connected in parallel.

2. Chemistry: Reactions and pH Values

Chemical reactions are the heart of the science practical for class 10 state board. 

• Experiment: Observing the action of Zn, Fe, Cu, and Al metals on salt solutions to determine the reactivity series. 

• Common Error: Failing to clean the metal strips with sandpaper before the experiment, which can lead to incorrect observations. 

3. Biology: Life Processes and Stomata

The temporary mount of a leaf peel is a classic board favorite. 

• Focus: Identifying the guard cells and stomatal pore. 

• Project Book Tip: When drawing in your science project book for class 10, use a sharp HB pencil and label everything on the right side of the diagram. 

Mastering the Science Project Book for Class 10 

Your project book is the first thing an external examiner sees. To ensure you get full marks for your record: 

1. Index Accuracy: Ensure your index matches the experiments in the book. 

1. Clean Diagrams: Avoid using pens for diagrams. Stick to pencils. 

1. Observation Tables: Data should be neat and include proper units (e.g., Ohms, Volts, cm).

How to Handle the Viva Voce Like a Pro 

The Viva accounts for a significant portion of your practical marks. Examiners in 2026 are moving away from rote definitions and asking “Reasoning Questions.” Instead of just asking “What is pH?”, they might ask, “Why did the lemon juice turn the pH paper red?” 

At Tutoroot, we provide specialized “Viva Simulation” sessions where our experts help you practice these real-time questions, ensuring you walk into the lab with absolute confidence. 

 

Frequently Asked Questions (FAQ) 

Q1: What are the passing marks for Class 10 Science Practicals? 

You must score at least 33% in the practical component separately to pass the overall subject. 

Q2: Can I use a calculator during the Science Practical exam? 

Calculators are generally not allowed; you should practice basic calculations for Ohm’s Law and focal length manually. 

Q3: What if my experiment results are slightly off from the theoretical value? 

Don’t panic; examiners look for your “Experimental Skill” and how you explain the error in your conclusion. 

Q4: Is the science project book for class 10 mandatory for the final exam? 

Yes, it is a compulsory record that must be certified by your subject teacher to allow you to sit for the practical. 

Q5: How should I prepare for the Science Viva? 

Focus on the “Why” behind each experiment and memorize the basic formulas and chemical equations involved in your syllabus. 

Q6: What happens if I miss my practical exam date? 

Inform your school immediately; missing the practical can result in an “Incomplete” status on your final board marksheet. 

 

Conclusion: 

Completing the science practical for class 10 state board answers is the first step toward board exam success. As you wrap up your records, remember that these experiments form the foundation of the difficult 5-mark questions in your theory paper.
