Science & Pedagogy MCQs Previous Year Questions, Decoded
Real questions from past CTET papers with explanations that go beyond just the answer — because understanding beats memorising every time.
📚 Paper II — Class 6 to 8🔬 Science + Pedagogy✅ 30 Questions Covered📅 2018–2023 Papers
If you've been preparing for CTET Paper II and feel like Science pedagogy questions are unpredictable — you're right, and you're wrong. They're not random. Once you map the pattern across years, the same ideas keep showing up in different clothing. NCF 2005, constructivism, inquiry-based learning, assessment for learning. These aren't buzzwords. They're the backbone of nearly every pedagogy question in the last six years.
This post goes through actual previous year questions with proper explanations. Not just "answer is B" — but why B, why not A, and what the examiner was really testing.
Before You Begin
What's Actually in the Syllabus?
CTET Paper II Science section carries 60 marks — 40 for content and 20 for pedagogy. The 20 pedagogy marks are where most aspirants either gain a solid edge or throw away easy marks. Here's the breakdown:
Content Areas (40 Marks)

Science Pedagogy — Real MCQs with Explanations
These are verified questions from CTET papers between 2018 and 2023. Read the explanation for every question, even the ones you get right on the first try.
📄 CTET July 2023
Q.01 · Pedagogy
Which of the following approaches best supports inquiry-based learning in a science classroom?
A Teacher explains the concept and students take notes
B Students are asked to memorise scientific definitions from the textbook
C Students are encouraged to ask questions, conduct investigations and draw conclusions
D Teacher conducts the experiment and students observe and record results
Answer: C
Inquiry-based learning puts the student at the centre — they generate questions, design investigations, analyse data, and draw their own conclusions. Option D might sound hands-on, but if only the teacher is doing the experiment, students are still passive observers. The keyword here is "students are encouraged" — agency matters.
Exam tip: Whenever a question asks about ideal pedagogy, look for the option where students are most active and the teacher is least directive. That's usually the right answer in CTET's framing.
Q.02 · Pedagogy
In the context of science education at upper primary level, which statement about assessment is most appropriate?
A Assessment should focus mainly on testing factual recall
B End-of-year exams are the most reliable way to evaluate science learning
C Assessment should be continuous and include performance tasks, projects, and observations
D Only written tests can accurately measure scientific understanding
Answer: C
This aligns with NCF 2005's position on Continuous and Comprehensive Evaluation (CCE). Science learning, especially at upper primary level, involves process skills — observation, prediction, experimentation — that cannot be captured in a single written test. The CTET consistently rewards the idea of diverse, ongoing assessment.
Q.03 · Pedagogy
A teacher wants to explain the concept of photosynthesis to Class 7 students. Which method would be most appropriate?
A Reading aloud from the NCERT textbook and then conducting a Q&A
B Showing a documentary and asking students to write a summary
C Conducting a simple leaf experiment followed by student discussion and explanation
D Giving students a detailed diagram to copy and label in their notebooks
Answer: C
Photosynthesis is a process — it's best understood through experience, not description. Option C combines hands-on activity with collaborative sense-making (discussion). Copying diagrams (D) reinforces motor skills but not conceptual understanding. The CTET frequently distinguishes between activities that look like science and activities that are actually science.
📄 CTET December 2022
Q.04 · Pedagogy
According to NCF 2005, the main aim of science education at the upper primary stage should be:
A Preparing students to pass board examinations
B Developing the ability to memorise scientific facts and formulae
C Helping students engage with the natural world and develop scientific temper
D Training students for competitive examinations like Olympiads
Answer: C
NCF 2005 explicitly states that science education should cultivate "scientific temper, curiosity and creativity." The phrase "engage with the natural world" is straight from NCF's language. Exam prep (A and D) is never presented as a primary goal in NCF — if anything, NCF pushes against rote-oriented schooling.
NCF 2005 Watch: Options mentioning "exam preparation," "competition," or "memorisation" are almost always wrong in pedagogy questions. NCF's language runs in the opposite direction.
Q.05 · Pedagogy
A constructivist science teacher would MOST likely:
A Provide a step-by-step method for students to follow in every experiment
B Test students' factual knowledge at the end of each chapter
C Build on students' prior knowledge and help them construct new understanding through experience
D Ensure students complete the prescribed syllabus before the exam
Answer: C
Constructivism (Piaget, Vygotsky) holds that learners build understanding through experience, not passive reception. The key phrase is "prior knowledge" — a constructivist teacher always begins by activating what students already know. Option A is prescriptive and leaves no room for student thinking. Option D is administration, not pedagogy.
Q.06 · Pedagogy
Which of the following is an example of formative assessment in a science classroom?
A Annual examination at the end of the academic year
B Half-yearly test conducted in October
C Observing students during a group experiment and giving immediate feedback
D Marks awarded in the CBSE Class 8 board-style examination
Answer: C
Formative assessment happens during learning, not after it. Its purpose is to inform instruction and provide feedback in real time. Options A, B and D are all summative — they measure learning after instruction is complete. The word "immediate feedback" in option C is the signal.
📄 CTET January 2021
Q.07 · Pedagogy
Which of the following would BEST promote scientific literacy among upper primary students?
A Teaching students to solve numerical problems in physics
B Asking students to read and summarise chapters from the textbook weekly
C Exposing students to real-world issues and encouraging them to think critically using scientific reasoning
D Making students memorise the periodic table and key biological terms
Answer: C
Scientific literacy is not about knowing more facts — it's about using scientific thinking in everyday contexts. Option C connects science to the real world and demands higher-order thinking. Options A and D confuse content knowledge with literacy. Option B builds reading habits but not scientific reasoning.
Q.08 · Pedagogy
A science teacher notices that several students hold the misconception that "heavier objects fall faster than lighter ones." What is the MOST appropriate response?
A Correct the misconception by telling students the right answer directly
B Mark those students' answers wrong in the test and move on
C Design an activity where students drop objects of different masses and observe the outcome, then discuss
D Ask students to write "heavier objects do not fall faster" five times as a correction
Answer: C
Misconceptions in science aren't corrected by telling — they're corrected by experience that creates cognitive conflict. When students see objects of different masses fall at the same rate (in the absence of air resistance), it disrupts their existing mental model. Option A might produce the right statement without changing the underlying belief. Option D is counterproductive.
Key concept: "Conceptual change" — students need to encounter an experience that challenges their existing understanding. CTET loves this concept. Look for it in questions about misconceptions, prior knowledge, and alternate conceptions.
📄 CTET July 2019
Q.09 · Pedagogy
Which of the following best describes the role of a science teacher in a child-centred classroom?
A To transmit knowledge from the textbook to students efficiently
B To maintain discipline so that students can focus on listening
C To facilitate learning by creating situations where students explore and discover
D To ensure that the entire syllabus is covered before March
Answer: C
"Facilitator" is the key word here. A child-centred classroom shifts the locus of activity from teacher to student. The teacher's job is to set up rich learning environments, not to deliver information. Option A is the transmission model of teaching — the one NCF 2005 explicitly critiques.
Q.10 · Pedagogy
The purpose of using a science laboratory at the upper primary level is primarily to:
A Verify the theories and facts already taught in the classroom
B Help students pass practical examinations
C Enable students to develop process skills like observation, measurement and experimentation
D Demonstrate complex experiments that cannot be explained through diagrams
Answer: C
Lab work at upper primary level isn't about proving what's already been said in class (Option A treats the lab as a verification machine). It's about building process skills — which are transferable scientific skills. CTET's framing always prioritises skill development over content coverage.
📄 CTET September 2018
Q.11 · Pedagogy
Which of the following teaching strategies encourages cooperative learning in a science class?
A Assigning individual research tasks and presenting to the class
B Competitive science quiz where one student wins
C Group experiments where students assign roles, share responsibility, and report collectively
D Teacher-directed demonstrations followed by individual note-taking
Answer: C
Cooperative learning (Johnson & Johnson, Vygotsky's ZPD) involves structured group work with shared accountability. The phrase "shared responsibility and collective reporting" is the marker here. A quiz (B) creates competition, not cooperation. Option A is individual, not cooperative.
Q.12 · Pedagogy
A teacher uses role play to explain the movement of planets around the sun. This is an example of:
A Rote learning technique
B Summative evaluation
C Simulation as a teaching strategy
D Demonstration method
Answer: C
Simulation involves recreating a real-world process through an analogous activity. Students acting as planets create an embodied understanding of orbital mechanics that a diagram cannot replicate. Option D (demonstration) would apply if the teacher were doing it — not the students.
Now for the Content Section
Content Questions
Science Content — Previous Year MCQs
These are from the content portion of the paper. The pattern here is application over recall — CTET rarely asks definitions straight up. It tests whether you can apply a concept in a given situation.
📄 Various Years (2018–2023)
Q.13 · Nutrition · 2022
Which of the following is the correct sequence of parts of the human digestive system?
A Mouth → Stomach → Oesophagus → Small intestine → Large intestine
B Mouth → Oesophagus → Stomach → Small intestine → Large intestine
C Mouth → Small intestine → Stomach → Oesophagus → Large intestine
D Mouth → Oesophagus → Small intestine → Stomach → Large intestine
Answer: B
The alimentary canal follows: Mouth → Pharynx → Oesophagus → Stomach → Small intestine (duodenum, jejunum, ileum) → Large intestine → Rectum → Anus. Option A is a common error — students sometimes reverse oesophagus and stomach. The oesophagus carries food from the mouth to the stomach, not the other way around.
Q.14 · Light · 2021
When a ray of light passes from a denser medium to a rarer medium at an angle greater than the critical angle, what phenomenon occurs?
A Normal refraction
B Dispersion of light
C Total internal reflection
D Diffraction
Answer: C
Total internal reflection (TIR) occurs when: (1) light travels from a denser to a rarer medium, AND (2) the angle of incidence exceeds the critical angle. Both conditions must be met. This principle explains optical fibre communication, mirage formation, and the brilliance of diamonds. CTET has tested TIR in several years — always in context.
Q.15 · Microorganisms · 2023
Rhizobium bacteria, found in the root nodules of leguminous plants, are important because they:
A Help in the decomposition of dead organic matter
B Produce antibiotics used to treat plant diseases
C Fix atmospheric nitrogen into compounds that plants can absorb
D Produce oxygen through photosynthesis
Answer: C
Rhizobium is a nitrogen-fixing bacterium — it converts N₂ from the atmosphere into ammonia (NH₃), which plants use to synthesise proteins. This is biological nitrogen fixation. Leguminous plants (pea, soybean, lentil) benefit from this symbiotic relationship. Option A describes decomposers like fungi and saprophytic bacteria.
Q.16 · Force & Motion · 2022
A ball is thrown vertically upward. At the highest point of its journey, what is the value of its velocity and acceleration?
A Velocity = 0, Acceleration = 0
B Velocity = maximum, Acceleration = 0
C Velocity = 0, Acceleration = 9.8 m/s² downward
D Velocity = maximum, Acceleration = 9.8 m/s² upward
Answer: C
At the highest point, the ball momentarily stops — so velocity = 0. But gravitational acceleration (g = 9.8 m/s²) acts continuously in the downward direction regardless of the ball's motion. This is a classic student misconception: many assume that if velocity is zero, acceleration must also be zero. They are independent quantities.
Common misconception: "If velocity is zero, acceleration is zero." This is wrong. A ball at rest on a slope has zero velocity but non-zero acceleration. Always distinguish between the two.
Q.17 · Cell Biology · 2019
Which organelle is called the "powerhouse of the cell" and why?
A Nucleus — because it controls all cell activities
B Ribosome — because it synthesises proteins for energy
C Mitochondria — because it is the site of cellular respiration and ATP production
D Chloroplast — because it produces glucose through photosynthesis
Answer: C
Mitochondria carry out cellular respiration — the process that converts glucose and oxygen into ATP (adenosine triphosphate), the cell's energy currency. The term "powerhouse" refers to ATP synthesis, not energy storage. Chloroplasts (D) produce glucose but are found only in plant cells. The nucleus (A) controls the cell but does not generate energy.
Q.18 · Natural Phenomena · 2021
Thunder is heard a few seconds after lightning is seen because:
A Lightning occurs before thunder in any thunderstorm
B The speed of light (3 × 10⁸ m/s) is much greater than the speed of sound (340 m/s)
C Thunder is an echo of lightning reflected from clouds
D Our ears take time to process sound after a lightning flash
Answer: B
Both light and sound are produced simultaneously during a lightning discharge. Light reaches your eyes almost instantaneously (3 × 10⁸ m/s). Sound travels at 340 m/s, covering 1 km roughly every 3 seconds. You can actually estimate the distance of a storm by counting seconds between the flash and the thunder, then dividing by 3.
Q.19 · Reproduction · 2018
Hydra reproduces by a process called budding. This is a type of:
A Sexual reproduction requiring two parents
B Regeneration from a detached body part
C Asexual reproduction where a bud grows from the parent and separates
D Vegetative propagation found only in plants
Answer: C
Budding in Hydra is asexual — a small outgrowth (bud) forms on the parent body, develops into a new individual, and eventually detaches. No gametes are involved. Regeneration (B) describes organisms like starfish and planaria, which can regrow from severed parts. Vegetative propagation (D) is a plant-specific term — though the underlying mechanism is similar.
Q.20 · Acids & Bases · 2023
Turmeric is used as a natural indicator. What colour does a turmeric stain turn in the presence of a base?
A Yellow
B Blue
C Red
D Green
Answer: C
Turmeric (containing curcumin) is yellow in neutral/acidic conditions but turns red (or brownish-red) in basic/alkaline conditions. This is why clothes stained with turmeric develop a reddish stain when washed with alkaline soaps. CTET has tested natural indicators — turmeric, red cabbage, and litmus — in multiple years.
Quick Reference
Pedagogy Concepts You Must Know Cold
These keep showing up. Not as definitions to recall, but as principles to apply. The question will give you a scenario and ask which option reflects the right approach.
Theory
Constructivism (Piaget & Vygotsky)
Learning is an active process where students build new knowledge on existing knowledge structures. Teachers don't fill empty vessels — they create conditions for students to make meaning. ZPD (Zone of Proximal Development) and scaffolding come from Vygotsky. CTET applies these to: collaborative learning, prior knowledge activation, group experiments, and open-ended tasks.
Framework
NCF 2005 — Key Positions on Science
NCF 2005 argues that science teaching should move away from rote learning toward nurturing curiosity and scientific temper. It recommends inquiry, hands-on activities, local context (connecting science to the child's environment), and assessment through projects and observations — not just tests. Any CTET option that aligns with these ideas is usually correct.
Assessment
Formative vs Summative
Formative assessment is ongoing, informal, and used to improve learning while it's happening — observation during activities, class discussion, exit slips. Summative assessment measures what was learned at the end — exams, term papers. CTET often asks you to distinguish between the two and identify which one serves what purpose.
Teaching Strategy
Inquiry-Based Learning (IBL)
Students pose questions, gather data, analyse findings, and draw conclusions — just like scientists do. The teacher sets the stage but doesn't script the outcome. IBL develops process skills (observation, inference, prediction) alongside content knowledge. CTET contrasts IBL with lecture-based teaching to test whether you can identify the more student-centred approach.
Concept
Misconceptions & Conceptual Change
Students arrive in class with pre-existing ideas — some accurate, many not. A good science teacher doesn't just correct misconceptions verbally. They design learning experiences that create "cognitive conflict" — situations where the student's existing belief breaks down and must be revised. This is conceptual change theory, and CTET tests it regularly through scenario-based questions.

The most common mistake: Spending 80% of prep time on science content and only 20% on pedagogy. The content section is more predictable — you either know mitosis or you don't. The pedagogy section rewards understanding of principles, and those principles can be learned in a week of focused reading.
Bonus Round
10 More Questions from Recent Papers
📄 Mixed (2019–2023)
Q.21 · Pedagogy · 2023
Science process skills include all of the following EXCEPT:
A Observation
B Inference
C Classification
D Memorisation
Answer: D — Science process skills are cognitive actions — observing, questioning, hypothesising, experimenting, inferring, classifying, communicating. Memorisation is not a process skill; it is a recall strategy. This distinction is fundamental to NCF's vision of science education.
Q.22 · Electricity · 2022
A fuse wire in an electric circuit melts when there is excessive current. The material of a fuse wire has:
A Low melting point and high resistance
B High melting point and low resistance
C High melting point and high resistance
D Low melting point and low resistance
Answer: A — A fuse must melt quickly (low melting point) when current exceeds safe limits, and must generate heat (high resistance) during excess current flow to trigger melting. If resistance were low, excess current wouldn't generate enough heat. Fuse wire is typically made of an alloy of lead and tin.
Q.23 · Pedagogy · 2021
While teaching about pollution, a teacher takes students to a nearby river and asks them to observe and record their findings. This type of activity is called:
A Laboratory experiment
B Role play
C Field trip / Field observation
D Simulation
Answer: C — Taking students to the actual environment (river, forest, market) for structured observation is a field trip. NCF 2005 strongly recommends connecting science learning to the local environment. Field trips develop observation skills and contextualise abstract concepts.
Q.24 · Sound · 2020
A sound wave has a frequency of 200 Hz and a wavelength of 1.65 m. What is its speed?
A 200 m/s
B 165 m/s
C 330 m/s
D 82.5 m/s
Answer: C — Speed = Frequency × Wavelength = 200 × 1.65 = 330 m/s. This is approximately the speed of sound in air at room temperature. This formula (v = fλ) is tested both directly and in context.
Q.25 · Pedagogy · 2019
Bloom's Taxonomy in the context of science education suggests that the HIGHEST cognitive level is:
A Understanding
B Applying
C Evaluating
D Creating
Answer: D — In Bloom's revised taxonomy (2001): Remember → Understand → Apply → Analyse → Evaluate → Create. Creating (designing experiments, formulating hypotheses, inventing) is the highest level. Many CTET papers test this ordering — know it from the bottom up.
Q.26 · Heat · 2023
Sea breeze blows from sea to land during the day because:
A Sea water is cooler and heavier, pushing air toward land
B Land heats up faster, hot air rises over land creating a low-pressure zone, and cooler sea air moves in
C The sea is at a higher altitude than the land
D Wind always blows from sea to land regardless of temperature
Answer: B — Land has lower specific heat capacity than water, so it heats up faster. Hot air over land rises, lowering pressure. Cooler, denser air from the sea flows inward to fill the gap. At night, the process reverses — land cools faster, so land breeze blows from land to sea.
Q.27 · Pedagogy · 2022
A student with visual impairment is in a science class. Which accommodation would be MOST appropriate?
A Give the student simpler questions to answer
B Exempt the student from practical work
C Provide tactile models, audio descriptions, and adapted materials for experiments
D Seat the student in the front row and speak louder during demonstrations
Answer: C — Inclusive education requires adapting the learning environment to the student's needs, not reducing expectations. Tactile models (3D representations of cells, structures) and audio support maintain the student's participation in the actual learning activity. Exempting a student (B) is exclusion, not inclusion.
Q.28 · Nutrition in Plants · 2021
Which gas is released by plants during photosynthesis?
A Carbon dioxide
B Nitrogen
C Oxygen
D Hydrogen
Answer: C — In photosynthesis: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂. Oxygen is released as a byproduct when water molecules are split (photolysis). Plants also perform cellular respiration (releasing CO₂), but during the day, photosynthesis rate exceeds respiration rate, so the net release is oxygen.
Q.29 · Pedagogy · 2018
Which of the following best describes "scientific temper" as used in NCF 2005?
A The ability to score high marks in science examinations
B Knowledge of all major scientific discoveries and scientists
C A rational, evidence-based approach to understanding the world, with a spirit of enquiry
D Interest in pursuing a career in science after school
Answer: C — Scientific temper, as described in NCF 2005 and the Indian Constitution (Article 51A), refers to a rational, evidence-based way of thinking — scepticism, openness to evidence, willingness to revise beliefs. It's a disposition, not a body of knowledge. This comes up across multiple years.
Q.30 · Ecology · 2023
Which of the following correctly describes a food chain starting with grass?
A Grass → Frog → Snake → Eagle → Grasshopper
B Grass → Grasshopper → Frog → Snake → Eagle
C Grass → Eagle → Snake → Frog → Grasshopper
D Grasshopper → Grass → Frog → Eagle → Snake
Answer: B — A food chain always begins with a producer (grass) and flows to progressively higher consumers. Grasshopper is a primary consumer (herbivore), frog is a secondary consumer, snake is a tertiary consumer, and eagle is the apex predator. Energy flows in one direction only: producer → consumer.
Final Word
What Actually Works in the Last 30 Days
If your exam is a month away, here's the honest picture. The content questions are predictable — focus on Class 6–8 NCERT thoroughly. Every question in the CTET content section traces back to NCERT. Don't go beyond it.
For pedagogy, read NCF 2005 Chapter 3 and the position paper on Science Education (it's in the NCF supplementary materials online — about 20 pages). After that, solve 5 years of previous papers in sequence and map which concept each pedagogy question was testing. You'll see the same ideas cycling.
One thing people consistently underestimate: elimination is your best friend in pedagogy MCQs. Even when you're unsure of the right answer, you can almost always rule out two options immediately — the one about rote learning and the one about exam preparation. That brings you to a 50-50 guess, which in a 2-option fight is actually fine odds.
Resources to use: NCERT Science Textbooks (Class 6, 7, 8) — read every intext question and activity. NCF 2005 — Chapter 3 and Science Position Paper. Previous year CTET papers (2018–2023) on the CTET official website. And practice in the actual 2.5-minute-per-question pace — speed matters on exam day.
