Why Are Practical Exams Important in Class 10?
Practical exams sirf marks ke liye nahi hote — ye aapki theoretical samajh ko real experiments se jodte hain. Humein mili jankari ke anusar, jo students practicals ko seriously lete hain, wo theory me bhi better perform karte hain. Ohm’s Law ya refraction of light jaise concepts jab aap khud perform karte ho, to yaad rehna aasaan ho jaata hai.
Iske alawa, practical skills aapke aage ke Class 11-12 science aur NEET/JEE jaise competitive exams me kaam aati hain. Cell observation, titration jaisi techniques, aur circuit connections — yeh foundation skills hain. Mindgroom ke ek detailed blog me bhi practical exams ki importance par acchi jaankari di gayi hai, jise aap Mindgroom Navneet Science guide par padh sakte hain.
Ek aur baat — practical marks aksar scoring hote hain agar tayyari sahi ho. Isliye Navneet science journal std 10 all practical answers 2019 board ko exam se pehle achhe se revise karna highly recommended hai.
Experiment-Wise Practical Answers
Ab hum subject-wise har major experiment ka structured answer de rahe hain. Humari team ne ise Navneet journal format ke hisaab se arrange kiya hai taaki aap seedha exam pattern me likh sakein.
Neeche table me complete experiment list di gayi hai jo commonly Class 10 Navneet journal me aati hai.
| S.No. | Experiment Name | Subject | Marks |
|---|---|---|---|
| 1 | Focal Length of Concave Mirror / Convex Lens | Physics | 10 |
| 2 | Verification of Ohm’s Law | Physics | 10 |
| 3 | Refraction Through Glass Slab / Prism | Physics | 10 |
| 4 | Identification of Halide Ions | Chemistry | 10 |
| 5 | Types of Chemical Reactions | Chemistry | 10 |
| 6 | Properties of Acetic Acid | Chemistry | 10 |
| 7 | Study of Stomata in Leaf Peel | Biology | 10 |
| 8 | Study of Mitosis and Meiosis | Biology | 10 |
| 9 | Study of Ecosystems | Biology | 10 |
Physics Practicals
Physics section me sabse common experiments hain focal length, Ohm’s Law, aur refraction of light. In teeno me accuracy aur neat diagram sabse zyada marks dilate hain.
Experiment 1
Focal Length of a Concave Mirror: Is experiment me aap ek distant object (jaise door ka building ya tree) ka image ek white screen par focus karte ho. Jab image sharp ho, tab mirror aur screen ke beech ki distance measure karo — yahi focal length (f) hai.
Teen readings lekar average nikaalna accuracy ke liye zaroori hai. Common mistake yeh hai ki students paas ka object choose kar lete hain — hamesha 20 meter se door ka object lo.
Experiment 2
Verification of Ohm’s Law: Is experiment me aap voltage (V) aur current (I) ke beech ka relation verify karte ho. Ammeter series me aur voltmeter parallel me connect hota hai — yeh basic rule bhoolna nahi hai.
Rheostat ko dheere-dheere adjust karke 5 readings lo aur R = V/I se resistance nikaalo. Graph hamesha straight line aata hai jo origin se guzarti hai, jo V ∝ I prove karti hai.
Experiment 3
Refraction Through Glass Slab: Is experiment me aap angle of incidence, angle of refraction aur angle of emergence measure karte ho.
Incident ray aur emergent ray hamesha parallel rehti hain. Pins ko vertical aur well-separated fix karna accuracy ke liye must hai. Snell’s law ke according, sin i / sin r ek constant value deta hai.

Chemistry Practicals
Chemistry section me precipitate reactions aur acid-base tests important hain. Humein mili jankari ke anusar, examiners yahan colour observations aur chemical equations par khaas dhyan dete hain.
Experiment 4
Identification of Halide Ions: Is experiment me aap KCl, KBr aur KI solutions me silver nitrate (AgNO₃) add karte ho. KCl se white precipitate (AgCl), KBr se light yellow (AgBr), aur KI se bright yellow (AgI) banta hai.
Precipitate ka colour hi halide ion identify karta hai. Chemical equation zaroor likhna — jaise KCl + AgNO₃ → KNO₃ + AgCl↓.
Experiment 5
Types of Chemical Reactions: Is experiment me aap combination, decomposition, displacement aur double displacement reactions study karte ho.
Magnesium ka jalna (2Mg + O₂ → 2MgO) ek combination reaction hai, jabki lead nitrate ko heat karna ek decomposition reaction hai.
Iron nails ko copper sulphate me daalna ek displacement reaction ka classic example hai. Sodium sulphate aur barium chloride ka reaction double displacement dikhata hai jisme white precipitate banta hai.
Experiment 6
Properties of Acetic Acid: Is experiment me aap acetic acid ke odour, solubility, litmus effect aur sodium bicarbonate reaction ko study karte ho.
Acetic acid ka smell vinegar jaisa hota hai aur yeh blue litmus ko red kar deta hai. Sodium bicarbonate ke saath reaction me CO₂ gas nikalti hai jo lime water ko milky banati hai.
Biology Practicals
Biology section me microscope observations aur neat labelled diagrams sabse zyada marks dilate hain. Humari team ne notice kiya ki students yahan diagram labelling me marks kho dete hain.
Experiment 7
Study of Stomata: Is experiment me aap leaf ke lower epidermis ka thin peel lekar microscope me observe karte ho. Low power (10x) par scattered stomata dikhte hain, aur high power (45x) par kidney-shaped guard cells clear hote hain.
Peel bahut thin hona chahiye warna kuch dikhega nahi. Air bubbles avoid karne ke liye cover slip 45-degree angle par rakho.
Experiment 8
Mitosis and Meiosis: Is experiment me aap onion root tip (mitosis) aur grasshopper testis (meiosis) ki permanent slides observe karte ho.
Mitosis me chromosome number same rehta hai, jabki meiosis ek reduction division hai jisme number aadha ho jaata hai. Prophase, metaphase, anaphase aur telophase ke diagrams neat labels ke saath banana zaroori hai.
Experiment 9
Study of Ecosystems: Is experiment me aap school playground ya pond jaise ecosystems ko study karte ho. Abiotic factors (soil, water, sunlight) aur biotic factors (plants, animals) ko note karo. Ek food chain ya food web banana is experiment ka important part hai.
Agar aapko in experiments ke image-based answers chahiye, to Pinterest par ek useful visual collection yahan available hai jise aap reference ke taur par dekh sakte hain.
Updated Marking Scheme 2025-26
Humein mili jankari ke anusar, 2025-26 pattern me har experiment 10 marks ka hota hai aur marks ab component-wise diye jaate hain.
Sirf answer likhne se poore marks nahi milte har section ka apna weightage hai. Neeche table me exact breakdown diya gaya hai.
| Component | Marks | Examiner Kya Check Karta Hai |
|---|---|---|
| Aim | 1 | Clear, one-line statement with correct terminology |
| Apparatus | 1 | Complete list, sirf relevant items |
| Diagram | 2 | Neat, labelled, pencil se banaya hua |
| Procedure | 3 | Sequential steps, koi critical step miss na ho |
| Observation | 2 | Proper table format, units ke saath |
| Result | 1 | Ek clear statement jo aim se match kare |
Diagram aur Procedure sabse zyada marks (2+3) carry karte hain, isliye inpar sabse zyada practice zaroori hai. Observation table me units likhna bhoolna nahi — yeh common galti hai jo marks katwati hai.
Viva Preparation Tips
Viva me examiner aapki conceptual understanding test karta hai, na ki sirf ratta. Humari team ne commonly poochhe jaane wale questions ko subject-wise summarise kiya hai. In answers ko loud padhne se aapki confidence badhti hai.
| Subject | Sample Viva Question | Short Answer |
|---|---|---|
| Physics | Focal length aur radius of curvature ka relation? | R = 2f |
| Physics | Ammeter series me kyun connect hota hai? | Kyunki iski resistance bahut kam hoti hai |
| Chemistry | pH scale ki range kya hai? | 0 se 14 |
| Chemistry | Acetic acid ka smell kaisa hota hai? | Vinegar jaisa |
| Biology | Guard cells ka function kya hai? | Stomata ko open/close karna |
| Biology | Meiosis ko reduction division kyun kehte hain? | Chromosome number aadha ho jaata hai |
Viva me hamesha shaant reh kar jawab do. Agar answer nahi aata, to guess maarne se behtar hai politely bata dena. Concept-based questions ab zyada poochhe jaate hain, isliye “kyun” aur “kaise” samajhna zaroori hai.
How to Score Full Marks
Full marks lane ke liye sirf answers yaad karna kaafi nahi — presentation aur practice dono matter karti hai. Humein mili jankari ke anusar, examiners neat aur organized answer sheets ko naturally prefer karte hain.
Neeche kuch practical steps diye hain jo aapki scoring improve kar sakti hain.
- Diagrams roz practice karo — har diagram kam se kam 3 baar banao, sirf pencil se.
- Observation tables memory se likhne ki practice karo, units ke saath.
- Precautions likhna — yeh aapki understanding dikhata hai aur bonus impression banata hai.
- Result statement chhota rakho, jo seedha aim se match kare.
- Viva ke liye top questions ko loud padho, taaki fluency aaye.
Common mistakes jo marks katwati hain:
- Pen se diagram banana (hamesha pencil use karo).
- Units miss karna observation me.
- Procedure ko paragraph me likhna instead of numbered steps.
- Unrealistic values likhna jaise baar-baar exact same reading.
Exam se 3 din pehle saare diagrams aur tables ek baar revise kar lena. Exam day par pencil, eraser aur ruler zaroor le jaana, aur mobile phone bilkul mat le jaana.
