The English medium section of the NCERT Exemplar Class 7 Science PDF covers all 18 chapters prescribed for CBSE schools across India. Each chapter-wise PDF includes a carefully curated mix of conceptual questions, numerical problems, and real-life application scenarios based on everyday experiences like food preparation, health conditions, weather patterns, electrical appliances, and water usage in households.
Why This Matters: Regular practice with exemplar problems helps students transition from rote memorisation to genuine understanding. The questions are designed to test not just recall but the ability to apply scientific principles in new contexts—a skill essential for success in Class 9 and Class 10 board examinations.
The 18 chapters span three major science disciplines. Biology chapters (1-3, 10-12, 16-18) cover nutrition, respiration, reproduction, and environmental science. Physics chapters (4, 8, 13-15) address heat, motion, electricity, and light. Chemistry chapters (5-6) introduce acids, bases, salts, and chemical transformations. The remaining chapters integrate multiple disciplines, helping students see science as interconnected rather than isolated subjects.

Sample Questions from NCERT Exemplar Class 7 Science
Understanding the question patterns helps students prepare more effectively. Here are representative examples from different chapters demonstrating the types of higher-order thinking questions included in the NCERT Exemplar Class 7 Science book:
Sample Question 1 (Chapter 1 – Nutrition in Plants): A plant is kept in a dark room for about 48 hours before conducting any experiment on photosynthesis. This is done to:
(a) Remove all starch from the leaves
(b) Ensure that the leaves are free from water
(c) Remove chlorophyll from the leaves
(d) Ensure that leaves contain enough oxygen
Answer: (a) Remove all starch from the leaves
Explanation: This process is called destarching. When kept in darkness, the plant cannot perform photosynthesis, so it uses up all the stored starch. This ensures that any starch detected after the experiment was produced during the experimental conditions only.
Sample Question 2 (Chapter 4 – Heat): When we touch a metal chair on a cold winter morning, it feels much colder than a wooden table kept in the same room. This happens because:
(a) Metal has higher temperature than wood
(b) Metal is a better conductor of heat than wood
(c) Wood has higher temperature than metal
(d) Both have equal temperature but different sizes
Answer: (b) Metal is a better conductor of heat than wood
Explanation: Both objects are at the same room temperature. However, metal being a good thermal conductor quickly transfers heat away from your hand, making it feel colder. Wood, being a poor conductor (insulator), transfers heat slowly, feeling relatively warmer to touch.
Sample Question 3 (Chapter 5 – Acids, Bases and Salts): Turmeric stain on a white shirt becomes reddish-brown when soap is applied on it during washing. This indicates that:
(a) Soap is acidic in nature
(b) Soap is basic in nature
(c) Soap is neutral
(d) Turmeric reacts with water
Answer: (b) Soap is basic in nature
Explanation: Turmeric acts as a natural indicator. It remains yellow in acidic and neutral solutions but turns reddish-brown in basic solutions. Since soap changes the colour of turmeric stain, it confirms that soap has a basic (alkaline) nature.
These examples illustrate how NCERT Exemplar questions go beyond textbook definitions to test practical application and logical reasoning—skills that directly prepare students for NCERT Exemplar Class 9 Science PDF content and eventually board examinations.
How to Use NCERT Exemplar Class 7 Science Effectively
Simply downloading the PDFs is not enough—strategic usage maximises learning outcomes. Here is a structured approach recommended by experienced CBSE teachers for getting the most from your NCERT Exemplar Class 7 Science PDF study sessions:
Important: Never attempt exemplar questions before completing the corresponding NCERT textbook chapter. The exemplar is designed to test deeper understanding, not to teach concepts from scratch. Complete the textbook first, including all in-text questions and exercises.
Step 1: Complete NCERT Textbook Chapter — Read the chapter thoroughly, underline key terms, and attempt all textbook exercises. Ensure you understand every concept, diagram, and activity mentioned. This typically takes 2-3 study sessions per chapter.
Step 2: Attempt Exemplar Without Answer Key — Download the chapter PDF and attempt all questions independently. Write your answers in a notebook rather than just thinking through them mentally. This active recall process strengthens memory retention significantly.
Step 3: Self-Assessment Using Answer Key — Check your responses against the provided answer key. For every incorrect answer, don’t just note the correct option—understand why your reasoning was flawed. This metacognitive analysis is where genuine learning happens.
Step 4: Create an Error Log — Maintain a dedicated notebook listing questions you got wrong, along with the correct reasoning. Review this error log before tests. Research shows that focused revision of weak areas is 3-4 times more effective than general revision.
Step 5: Weekly Revision Cycle — Aim to complete 2-3 exemplar chapters per week during regular school months. During examination preparation, revisit your error log and re-attempt previously difficult questions to ensure lasting understanding.
Students who follow this systematic approach typically see significant improvement in their analytical abilities. Many find that concepts learned through exemplar practice remain accessible even in NCERT Exemplar Class 10 Science PDF preparation years later.
Benefits of NCERT Exemplar Class 7 Science for CBSE Students
The NCERT Exemplar Class 7 Science book offers several distinct advantages that complement regular textbook study and coaching materials:
Higher-Order Thinking Skills (HOTS): CBSE has increasingly emphasised competency-based questions in school assessments. The exemplar’s application-based problems directly prepare students for this examination pattern, developing analytical and evaluative thinking from an early age.
Conceptual Clarity Over Memorisation: Many students memorise definitions and diagrams without understanding underlying principles. Exemplar questions expose gaps in understanding by presenting familiar concepts in unfamiliar contexts—you cannot answer correctly through memorisation alone.
Science Olympiad Preparation: The National Science Olympiad (NSO), NSTSE, and similar competitive examinations feature questions remarkably similar to NCERT Exemplar patterns. Regular exemplar practice provides excellent Olympiad preparation without requiring separate study materials.
Why This Matters: The thinking skills developed through Class 7 Exemplar practice create a foundation for success in Class 9 and Class 10, where board examination pressure increases significantly. Students who struggle with application-based questions in senior classes often lack this early foundation.
Self-Assessment Capability: With detailed answer keys provided, students can evaluate their own understanding independently. This develops self-directed learning habits essential for higher education success, where external guidance becomes progressively limited.
Reduced Examination Anxiety: Exposure to challenging question types during regular study reduces surprise and anxiety during actual examinations. Students who have tackled difficult exemplar problems find school test questions comparatively straightforward.
Free and Authoritative Resource: Unlike commercial question banks, NCERT Exemplar is prepared by subject experts appointed by the Government of India and is available completely free. The content is guaranteed to align with CBSE curriculum standards published at CBSE.gov.in for the 2025-26 academic session.
