Syllabus And Exam Patterns

ICSE Class 9 Science Syllabus & Exam Pattern: Complete Guide

The ICSE Class 9 Science curriculum, prescribed by the Council for the Indian School Certificate Examinations (CISCE), is a comprehensive foundation course covering Physics, Chemistry, and Biology. Achieving a thorough understanding of this syllabus and its examination pattern is crucial, as Class 9 provides the necessary academic base for the rigorous Class 10 Board Examination.

1.0Examination 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.

2.0Theory 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.

3.0Detailed ICSE Class 9 Science Syllabus

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

Physics Syllabus (Major Units)

Unit

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.

4.0Internal 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.

Frequently Asked Questions

The Class 9 Science examination is generally conducted as three separate 100-mark subjects (Physics, Chemistry, and Biology), although they may sometimes be combined into a single theory paper depending on the school's internal annual exam schedule; regardless, each branch must be passed separately and carries its own 80:20 distribution.

Section I is vital because it consists of compulsory short-answer questions that comprehensively cover every topic in the syllabus for that particular branch (P, C, or B), meaning a student must have mastered the fundamentals across the board to secure these 40 marks, as no internal choice is provided.

Preparation for Section II requires in-depth study of key concepts, demanding not just recall but also analytical skills for solving complex numerical problems in Physics, writing detailed explanations and balanced equations in Chemistry, and drawing and labelling detailed diagrams in Biology, allowing students to strategically answer the required four questions from the available choices.

The 20 marks for Internal Assessment in each Science branch are typically earned through a combination of components: marks for performing the Laboratory Experiments correctly, marks for maintaining a neat and accurate Practical File/Journal record, and marks for any assigned Projects or Assignments, often accompanied by a Viva-Voce (oral questioning).

In Physics, the topics demanding the most numerical practice are Motion in One Dimension (using equations of motion), Laws of Motion F = ma, and Fluids (especially problems involving Archimedes' Principle and density); in Chemistry, the primary focus for numerical practice lies in the application of the Gas Laws (Boyle's and Charles' Law).
