Preparing for Class 9 Science can sometimes feel overwhelming. The syllabus covers Physics, Chemistry, and Biology, and teachers often give long answer questions (LAQs) in exams that carry high marks. These questions demand detailed explanations, diagrams, and examples.
But here’s the good news: you don’t have to cram everything. With the right tricks, mnemonics, and smart study hacks, you can easily remember concepts, structure your answers, and score high.
In this blog, we’ll explore easy tricks to learn Class 9 Science LAQs and make revision fun and effective.

📌 Why Focus on Long Answer Questions?
1)They usually carry 3–5 marks each.
2)Writing them well boosts your overall percentage.
3)They test concept clarity, not just memory.
4)If you master LAQs, short answers become super easy automatically.
First before reading your work is seeing important question from everychapter which were highly important like diffusion in biology.

🔑 General Tricks for All Long Answer Questions
1. Use the "3S Formula" – Start, Support, Summarize
Whenever you get a long question:
1)Start with a definition or concept.
2)Support with explanation, steps, or diagram.
30Summarize with conclusion or importance.
👉 Example 1..: Explain Newton’s First Law.
Start: “Newton’s first law of motion is also called the law of inertia…”
Support: Give examples like a ball rolling, or passengers jerking forward in a bus.
Summarize: “Hence, Newton’s first law shows that force is needed to change motion.”
And also make a line on important terms like law of inertia in first example

2. Flowchart Trick
Instead of memorizing long paragraphs, write answers as flowcharts or bullet points. Teachers love well-organized answers.
👉 Example: Explain the process of photosynthesis
Flowchart:
Sunlight → Chlorophyll → Water absorbed → CO₂ taken → Glucose formed → Oxygen released
---
3. Diagram = 50% Marks Secured
In Science, if you’re confused about theory, draw a neat diagram. Even an average explanation + correct diagram = high marks.
👉 Examples:
1)Cell structure
2)Human heart
3)Distillation setup
4)Ray diagram
See you not want to make correctly like given jn book you can make easy also
---
4. Keyword Highlighting
Every answer has keywords (scientific terms). Underline them in your exam. Teachers quickly spot and give marks.
👉 Example: Instead of writing only:
“Respiration releases energy.”
Write:
“Respiration is a biochemical process in which glucose is broken down into energy (ATP) in the presence of oxygen.”
---
5. Mnemonic Magic
Make funny short forms or sentences to remember points.
👉 Example: Characteristics of living organisms – MR NERG
1)Movement
2)Respiration
3)Nutrition
4)Excretion
5)Reproduction
6)Growth

📘 Biology Tricks (Class 9 Science)
1. Cell Structure
Long questions often ask to “Explain parts of cell” or “Differences between plant and animal cell.”
👉 Trick: Use the mnemonic “CRaPS – CEMG”
1)Cell wall (only in plants)
2)Ribosomes
3)a (Cytoplasm – always present)
4)Plasma membrane
5)Structure (Nucleus, etc.)
6)CEMG = Chloroplast, Endoplasmic reticulum, Mitochondria, Golgi
👉 Diagram: Neat, labeled cell → 3 marks guaranteed.
---
2. Tissues
👉 Trick for Plant Tissues (PMCS):or like PCMs
Parenchyma
Merenchyma
Collenchyma
Sclerenchyma
👉 Trick for Animal Tissues (ECMN): or MEN C YOU CAN LEARN LIKE THIS
Epithelial
Connective
Muscular
Nervous
When explaining:
Write function + example + diagram.
---
3. Photosynthesis
Equation is key:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
👉 Trick: “6, 6, 6, 6” rule → 6 CO₂, 6 H₂O, Glucose (C₆…), 6 O₂.
---
4. Respiration
👉 Trick: Two types – Aerobic vs Anaerobic
Aerobic = “O₂ → More Energy (36 ATP)”
Anaerobic = “No O₂ → Less Energy (2 ATP)”
Use comparison table → easy marks.

⚗️ Chemistry Tricks (Class 9 Science)
1. Separation of Mixtures
Long question: “Explain different methods of separation.”
👉 Trick: Remember by “F-CE-MS-S” OR SOMETHING ELSE YOU CAN MAKE
1)Filtration
2)Crystallization
3)Evaporation
4)Magnetic separation
5)Sublimation
6)Simple/ Fractional distillation
Draw simple apparatus diagrams → easy scoring.
---
2. Laws of Chemical Combination
Law of conservation of mass: “Mass can neither be created nor destroyed.”
👉 Trick: “Before = After” (Think of weighing before and after reaction).
Law of constant proportion: “Elements combine in fixed ratio.”
👉 Trick: Water is always H₂O, never H₃O.
---
3. Atomic Structure
👉 Trick for subatomic particles:
Proton = Positive = 1 unit mass
Neutron = Neutral = 1 unit mass
Electron = Negative = negligible mass
👉 Easy sentence: “Pro Neut Eat” = Proton-Neutron-Electron.
---
4. Mixture vs Compound
👉 Table Trick (write differences in 3–4 points).
Example:
Mixture: Variable ratio, easy separation
Compound: Fixed ratio, chemical separation

⚡ Physics Tricks (Class 9 Science)
1. Motion Formulas
👉 Trick: “v² – u² = 2as” triangle
Write formulas in triangle → cover 3 questions.
👉 Trick sentence: “Very Unique Ass Story” → v² – u² = 2as.
---
2. Newton’s Laws
First Law = Inertia
Second Law = F = ma
Third Law = Action = Reaction
👉 Trick sentence: “I See Action” → Inertia, Second, Action-Reaction.
---
3. Gravitation
Formula: F = Gm₁m₂ / r²
👉 Trick: “More mass, more pull; more distance, less pull.”
Also remember free fall → “g = 9.8 m/s²”
---
4. Work, Power, Energy
👉 Trick: WPE
Work = Force × Displacement
Power = Work / Time
Energy = Capacity to do work

📝 Smart Answer Writing Tips
1. Always start with definition.
2. Use diagrams wherever possible.
3. Write in points, not paragraphs.
4. Underline keywords.
5. Use examples from daily life – teachers love practical answers.
6. Time management: Practice writing LAQs within 5–7 minutes each.

🎯 Final 5-Step Strategy to Learn LAQs
1. Make short notes with mnemonics + diagrams.
2. Revise with flowcharts before exam.
3. Practice past year questions.
4. Explain to yourself/others aloud – memory gets stronger.
5. Revise every Sunday to avoid last-minute panic.
BUT BEST WAY IF YOU HAVE TIME IS READ AND UNDERSTAND WHOLE CHAPTER THAN DO WRITING PRACTISE
