CBSE Sample Papers for Class 9 Science 2026-27 with Answers and Solutions (Exploration)

Start your final exam preparation with Sample Paper Set 1 to 4. Each paper tests the full Class 9 Science syllabus in three sections: Biology for 30 marks, Chemistry for 25 and Physics for 25. Solutions for all four papers are available now. Solve each one in 3 hours, then check your answers, diagrams and units step by step.

Papers 5 to 8 give you more full syllabus practice, including chapters new to Class 9 such as Reproduction: How Life Continues, Patterns in Life: Diversity and Classification, and Earth as a System. The solution of Paper 5 is available now, and the answers for Papers 6, 7 and 8 will be released in November 2026. Write complete answers before you open any answer key.

December is the month to test all 13 chapters together. Papers 9 to 12 move from cells, tissues and classification in Biology to atoms, mixtures and the law of conservation of mass in Chemistry and on to numericals on motion, work and energy in Physics. This shows you which section costs you the most marks. Step-by-step solutions for this set will be released in December 2026.

Use these model papers as mock tests for your term 2 and annual exam preparation. Solve each paper in one 3-hour sitting. Give extra attention to the 4-mark and 5-mark questions built on figures, experiments and real-life situations, where full, reasoned answers earn the most marks. Answers and solutions for Papers 13 to 16 will be released in January 2027.

This last set is built for final revision before the Class 9 Science final exam 2027. Solve Papers 17 to 20 just as you would the real question paper, with correct SI units, neat labelled diagrams and full working. Revise the experiments in your practical syllabus alongside them. Answers and solutions for this set will be released in February 2027.

1. Finish each chapter in Exploration using NCERT Solutions, including its activities, before you attempt a full syllabus paper.
2. Download one sample paper PDF a week and solve it in a strict 3-hour sitting, with your book and notes closed.
3. Plan your time by section: about 60 minutes for Biology (30 marks), 50 for Chemistry (25 marks) and 50 for Physics (25 marks), leaving 20 minutes to revise.
4. In “identify the scientific term” questions, read every option carefully, because the wrong choices are usually terms from the same chapter.
5. When a question asks you to critically examine a claim, state clearly whether it is correct and support your view with at least two scientific reasons.
6. In experiment-based questions, state the hypothesis being tested and name the variables that must be kept the same.
7. In numericals on motion, work, energy and atomic structure, write the formula, substitute values with units, use g = 10 m s⁻² unless told otherwise and give the answer in the correct SI unit.
8. Read every figure closely and draw neat, labelled diagrams in pencil wherever an answer needs one.
9. When the answers and solutions are released, mark your paper honestly, list your mistakes section by section, revise those chapters and re-solve the wrong questions a week later.

• Textbook: NCERT Exploration (new syllabus 2026-27), one integrated book covering Biology, Chemistry, Physics and Earth Science
• Total chapters: 13. Chapter 1, Entering the World of Secondary Science, is an introduction and is not listed under any unit.
• Paper format: 39 compulsory questions, 80 marks, 3 hours
• Section A, Biology: Questions 1–16, 30 marks
• Section B, Chemistry: Questions 17–29, 25 marks
• Section C, Physics: Questions 30–39, 25 marks, including questions from Earth as a System such as ocean currents and the carbon cycle
• Question mix: 20 one-mark, 6 two-mark, 7 three-mark, 3 four-mark and 3 five-mark questions
• Internal choice: three questions in each section offer an OR option
• Question styles: identify-the-term MCQs, short scientific notes, claim-check and experiment-design questions, figure-based questions and numericals
• Internal assessment: 20 marks (Periodic Assessment 5, Multiple Assessment 5, Portfolio 5, Subject Enrichment/Practical Work 5)
• CBSE unit-wise weightage: World of Living 27 marks (Cell; Tissues in Action; Reproduction; Patterns in Life), Matter: Its Nature and Behaviour 25 marks (Mixtures; Journey Inside the Atom; Atomic Foundations of Matter), Motion, Force, Work and Sound 23 marks (Motion; Forces; Work, Energy and Simple Machines; Sound Waves), Earth as a System 5 marks
• Competency weightage: 50% knowledge and understanding, 30% application, 20% analysing, evaluating and creating
• Practical syllabus: 13 experiments, including separating mixtures by chromatography and sublimation, temporary mounts of onion peel and cheek cells, and verifying Newton’s second law
• Two levels of Science: every student takes the 80-mark main paper. An optional 25-mark, 1-hour advanced paper is shown separately on the mark sheet and not added to the total. These 20 papers prepare you for the main paper.

Solved sample papers show you exactly where you lose marks, but the marks themselves come from understanding Exploration. Every question in these papers is rooted in the textbook, so when a paper exposes a weak spot, whether it is tissues, atomic structure or the laws of motion, revise that chapter before you attempt the next one. Our NCERT Solutions for Class 9 Science Exploration explain the answers to every chapter step by step, which keeps this revision quick and focused. Solve one paper a week, check it against the answers as soon as they go live and by February you will walk into your Class 9 Science final exam well practised and confident.
