Sample Exemplar Questions with Solutions

Understanding the pattern and difficulty level of NCERT Exemplar Class 10 Science questions helps students prepare more effectively. Below are representative problems from different sections demonstrating the analytical approach required.

Solution Approach: The gas producing a ‘pop’ sound is hydrogen (H₂). This is a characteristic test for hydrogen gas. The balanced equation is: Zn + 2HCl → ZnCl₂ + H₂↑. This is a displacement reaction where zinc displaces hydrogen from hydrochloric acid because zinc is more reactive than hydrogen in the reactivity series. Students must note that such questions require identification of reaction type, product prediction and proper balancing—all tested in board examinations.

Solution Approach: The rate of heat development is the power of the heater. Using P = I²R, we get P = (15)² × 8 = 225 × 8 = 1800 W or 1.8 kW. The exemplar tests whether students can distinguish between total heat produced (H = I²Rt) and rate of heat production (P = I²R). This conceptual clarity is essential for solving numerical problems correctly in examinations.

Solution Approach: The cross is Tt × tt. Using a Punnett square: offspring genotypes are Tt and tt in equal proportion (1:1). Phenotypically, Tt plants are tall and tt plants are dwarf. Therefore, the phenotypic ratio is 1:1 (tall:dwarf). This type of question tests application of Mendelian inheritance principles and ability to predict outcomes of genetic crosses—a frequently examined topic in CBSE board examinations.

NCERT Exemplar Class 10 Science Hindi Medium PDF

For students studying in Hindi medium schools, the NCERT Exemplar Class 10 Science PDF is available in Hindi (विज्ञान) with identical content and question quality. The Hindi medium exemplar maintains the same chapter structure and difficulty level, ensuring that language preference does not affect preparation quality. All scientific terminology is provided with appropriate Hindi translations alongside English terms, helping students understand concepts in their preferred language while remaining familiar with technical vocabulary.

The Hindi medium PDFs are particularly beneficial for students from CBSE-affiliated schools in Hindi-speaking states who find it easier to comprehend complex scientific concepts in their mother tongue. Teachers in these schools can use the exemplar problems for classroom discussions, weekly tests and revision assignments. Students who have built their foundation using NCERT Exemplar Class 7 Science PDF in Hindi medium will find the transition to Class 10 content smoother.

The availability of exemplar resources in both languages reflects NCERT’s commitment to inclusive education. Students should choose the medium they are most comfortable with, as understanding concepts clearly is more important than the language of instruction. Many students also benefit from cross-referencing both versions when preparing difficult topics.

How to Use NCERT Exemplar for Board Exam Preparation

Effective utilisation of the NCERT Exemplar Class 10 Science PDF requires a strategic approach rather than random problem-solving. Following a structured method ensures comprehensive preparation and optimal time management during the crucial months before board examinations.

Step 1: Complete the NCERT Textbook First – Before attempting exemplar questions, ensure you have thoroughly read the relevant chapter from your NCERT textbook. Understand all concepts, diagrams, and solved examples. Complete the textbook exercises and verify your answers. The exemplar is designed to build upon textbook knowledge, not replace it.

Step 2: Attempt Exemplar Questions Chapter-Wise – After completing each textbook chapter, download the corresponding exemplar PDF and attempt all questions. Start with MCQs to test basic understanding, then progress to short answer questions and finally attempt long answer problems. This gradual increase in difficulty helps build confidence.

Step 3: Analyse Your Mistakes – When checking solutions, do not merely note the correct answer. Understand why your approach was incorrect and identify the conceptual gap. Maintain an error log noting the topic, mistake made and correct method. Review this log before examinations to avoid repeating errors.

Step 4: Time Your Practice Sessions – As board examinations approach, practise exemplar questions under timed conditions. Allocate time per question based on marks (approximately 1 minute per mark) and train yourself to complete problems within these limits. This prevents time management issues during actual examinations.

Students preparing systematically can also explore NCERT Exemplar Class 6 Science PDF for quick revision of basic concepts that form the foundation for Class 10 topics, especially in areas like electricity, light and living organisms.
