2.0Examination Pattern and Marking Scheme

Science is treated as a composite subject within Group II of the ICSE structure. The assessment follows a mandatory 80:20 ratio for each of the three branches.

Total Marks Distribution (Per Science Branch)

Particulars	Details
Total Marks per Subject (P/C/B)	100 Marks (300 marks total for Science)
Theory Paper (External Exam)	80 Marks (per branch)
Internal Assessment (Practical/Project)	20 Marks (per branch)
Duration of Theory Paper	Typically 2 to 2.5 Hours (per paper)
Passing Criteria	Generally 33% to 35% in aggregate (Theory + IA) per subject.

3.0Theory Paper Structure (80 Marks per Branch)

The 80-mark theory paper for Physics, Chemistry, and Biology is divided into two mandatory sections, testing both fundamental knowledge and application skills.

Section	Marks	Format & Focus	Preparation Strategy
Section I	40 Marks	Compulsory Short Answer Questions: Covers the entire syllabus of the specific branch. Includes objective-type, VSA questions, definitions, balancing equations, and short numerical problems.	Master all topics for conceptual recall; this section offers no internal choice.
Section II	40 Marks	Descriptive Questions: Candidates must typically answer four questions out of six or seven offered. These are long-answer questions, derivations, complex numericals, and detailed explanatory answers.	Strategic Depth—Master strong chapters to utilize the internal choice effectively for scoring maximum accuracy.

4.0Detailed ICSE Class 9 Science Syllabus

The syllabus is structured to provide conceptual depth in each scientific discipline.

Heat & Energy	Concepts of Heat and Temperature, Anomalous Expansion of Water, Thermometers, Renewable/Non-renewable Energy Sources.	Understanding the practical significance of anomalous expansion.
Waves	Reflection of Light (Spherical mirrors, ray diagrams), Nature of Sound Waves (Speed, echo, applications of Infrasonic/Ultrasonic).	Accurate ray diagram practice and numericals based on sound/echo.
Electricity & Magnetism	Current Electricity (Electric circuit, conductors/insulators), Magnetism (Properties of a bar magnet, induced magnetism).	Understanding the basics of circuit components and magnetic field concepts.

Chemistry Syllabus (Major Units)

Unit	Major Chapters / Topics / Subtopics	Key Focus Areas
Fundamentals	The Language of Chemistry (Symbols, Valency, Radicals, Balancing simple chemical equations), Elements, Compounds, and Mixtures.	Proficiency in writing and balancing chemical equations.
Atomic Structure & Bonding	Atomic Structure (Sub-atomic particles, Atomic number, Mass number), Chemical Bonding (Electrovalent and Covalent bonding).	Understanding the difference between isotopes and isobars.
Physical Chemistry	Study of Gas Laws (Boyle's Law, Charles' Law, relation to Kelvin scale), Chemical Changes and Reactions (Types, energy changes).	Application of Gas Laws to numerical problems.
Applied Chemistry	Water (as a compound/solvent, hard/soft water), Periodic Table (Historical development, Modern Periodic Law, brief study of Hydrogen).	Understanding the causes and remedies of hard water.

Biology Syllabus (Major Units)

Unit	Major Chapters / Topics / Subtopics	Key Focus Areas
Basic Biology	The Cell (structure, organelles, functions), Tissues (Plant and Animal tissues), Five Kingdom Classification (brief outline).	Detailed diagrams and functions of cell organelles.
Plant Life	The Flower (parts and functions), Pollination and Fertilisation, Germination of seeds (structure and necessary conditions), Respiration in Plants.	Understanding the conditions necessary for successful seed germination.
Human Anatomy & Physiology	Nutrition (Digestive System), Skeleton (Axial and Appendicular), Respiratory System, Skin.	Identifying organs and understanding their major functions in brief.
Health & Ecology	Health and Hygiene (Causes of diseases: Bacterial, Viral, Protozoan), Waste Generation and Management (Brief study).	Relating biological concepts to practical health issues and environmental management.

5.0Internal Assessment (Practical/Project Work) - 20 Marks

The 20 marks allocated for Internal Assessment (IA) in each Science branch are earned through practical and project work evaluated by the school teacher.

Assessment Focus: The IA assesses Laboratory Work (performing prescribed experiments), maintaining a Practical File/Journal (recording observations and procedures), and completing Assignments/Projects (research, models) which may include a Viva-Voce.
Strategic Advantage: Consistent, quality performance in the lab and timely submission of files and projects are the easiest ways to secure these 60 marks (20 in each P, C, B), which significantly boosts the overall final score.
