Syllabus And Exam Pattern

ICSE Class 10 Science Syllabus & Exam Pattern

The syllabus and testing approach of the ICSE Class 10 Science syllabus and pattern (2026) assess students’ ability to analyze and understand the key concepts of science and incorporate these elements into everyday life. The subject comprises Physics, Chemistry, Biology, and allows students to gain a strong foundation and understanding of the natural and physical world.

At ALLEN, we strongly advocate for conceptual learning and regular practice offered to students through ICSE Science materials, prior year papers, and mock tests, driving students to strengthen their fundamentals which allows them to achieve great success in their 2026 board examination.

2.0ICSE Class 10 Science Syllabus 2026

The ICSE Science syllabus contains 3 types of branches: Physics, Chemistry, and Biology. Each of these branches instils conceptual understanding and practical application of each area of science and builds upon the course of scientific reasoning and observation.

Students need to focus precisely on their theoretical understandings as well as their laboratory experiments, as both will support them in achieving the right score.

Branch	Unit / Topic	Key Concepts Covered
Physics	Force, Work, Power & Energy	Laws of motion, Machines, Power, and Energy transformations
	Light	Reflection, Refraction, Lenses, Ray diagrams
	Sound	Wave motion, Frequency, Resonance, Applications
	Electricity & Magnetism	Ohm’s Law, Circuits, Electromagnetism, Household wiring
	Modern Physics	Radioactivity, Nuclear energy, Application of X-rays
Chemistry	Periodic Table & Chemical Bonding	Modern periodic trends, Ionic & Covalent bonds
	Mole Concept & Stoichiometry	Atomic mass, Mole calculations, Chemical equations
	Acids, Bases & Salts	Properties, pH, Neutralization, Uses
	Analytical Chemistry	Tests for anions & cations, Identifying salts
	Metals & Electrolysis	Extraction of metals, Corrosion, Electroplating
	Organic Chemistry	Hydrocarbons, Alcohols, Acids, Basic reactions
Biology	Cell Biology & Genetics	Structure of cells, Chromosomes, Inheritance patterns
	Plant & Human Physiology	Photosynthesis, Respiration, Circulation, Excretion, Reproduction
	Health & Hygiene	Diseases, Immunization, First aid
	Ecology & Environment	Ecosystems, Pollution control, Conservation
	Applied Biology	Biotechnology, Food preservation, Waste management

3.0ICSE Class 10 Science Exam Pattern 2026

The ICSE Class 10 Science paper is divided into two parts — Theory and Practical (Internal Assessment).

Section	Type of Questions	Marks	Details
Part 1 (Section A)	Compulsory Short Answer Questions	40 Marks	Covers all three branches — Physics, Chemistry, and Biology
Part 2 (Section B)	Long Answer / Application-Based Questions	40 Marks	Attempt any 4 out of 6 questions
Total (Theory Paper)	—	80 Marks	Duration: 2 hours
Internal Assessment	Practical Work, Project, and Class Tests	20 Marks	Based on experiments and scientific reporting

Internal Assessment Breakdown (20 Marks)

Practical Work (10 Marks): Based on Physics, Chemistry, and Biology experiments
Project Work (6 Marks): Individual or group projects on applied Science topics
Class Performance (4 Marks): Regular tests and viva performance

4.0Chapter-Wise Marks Weightage

In the ICSE board exam, the numerical and reasoning based questions from Physics and Chemistry largely augment the toppers scores. There are also some regular questions from Biology related to drawing diagrams, so practice drawing neat, labeled diagrams as often as possible.

Here's an estimation of the marks distribution for the ICSE Class 10 Science exam based on an analysis from the past exams by experts from ALLEN:

Subject	Weightage (Approx.)	Focus Areas
Physics	25–30 Marks	Electricity, Light, Force & Energy, Sound
Chemistry	25–30 Marks	Periodic Table, Mole Concept, Electrolysis, Organic Chemistry
Biology	25–30 Marks	Human Physiology, Genetics, and Ecology
