Updated for 2026–27: This page contains an archived SCO Olympiad Class 6 Science previous-year practice paper with questions and an answer key. The material has been refreshed so students can use the older paper with clearer guidance and current Class 6 study context.
Use this paper to practise Class 6 science concepts, reasoning, diagrams, everyday applications and timed problem-solving. It is best used as a practice and diagnostic resource rather than as a substitute for the current school syllabus or the instructions printed on a current SCO Olympiad paper.
For school-level revision, students should also stay aligned with the current Class 6 Science curriculum. NCERT currently lists the Class VI Science textbook as Curiosity, so older Olympiad questions may use chapter names or examples that differ from the latest textbook structure.

The embedded PDF below is an SCO Olympiad practice resource. Students who want to continue with current preparation can also explore SCO International Science Olympiad resources after completing the paper.
How to Use This Class 6 Science Olympiad Paper
- Attempt the paper once without looking at the answer key.
- Use a timer so you practise both speed and accuracy.
- Mark questions you guessed and review the related concept afterwards.
- Group mistakes into areas such as materials, air, plants, body movements, motion and electricity so weak topics are easy to spot.
- Repeat difficult questions after revision instead of memorising the answer choices.
Important: exam-day instructions can change over time. Always follow the instructions printed on the current SCO Olympiad admit card and question paper rather than relying on old OMR-sheet directions from an archived paper.

The substance X is ________. a – Washing soda b – Baking soda c – Caustic soda d – Soda water |
| 5. Select the INCORRECT match. a – Petiole: Attaches the leaf to the stem b – Lamina: Green, flat part of the leaf c – Margin: Gives shape to the leaf edge d – Veins: Transpiration |
| Q 6. Which process is explained below? It is the process of making yarn from fibers. In this process, fibers from a mass of cotton wool are drawn out and twisted. This brings the fibers together to form a yarn. a – Weaving b – Spinning c – Knitting d – Ginning |
Q 7. Identify the joint X shown in the given figure.  a – Ball and socket joint b – Pivotal joint c – Knee joint d – Hinge joint |
| 8. Mini moves on a straight road from point P to point R. She takes 30 minutes to cover a certain distance (PQ) and 40 minutes to cover the rest of the distance (QR). She then returns back and takes 40 minutes to cover the distance RQ and 30 minutes to cover the rest of the distance to her starting point. She makes 5 rounds on the road in the same way. Mini concludes that her motion is ___________. a – Only rectilinear motion b – Only periodic motion c – Rectilinear and periodic motion d – Neither rectilinear nor periodic motion |

Quick Explanations for Selected Answers
- Q2: An inverted bottle contains air. When it is tilted under water, air escapes as bubbles and water enters the bottle.
- Q4: Caustic soda absorbs carbon dioxide, which is why it is used in demonstrations that examine the major gases present in air.
- Q5: Leaf veins transport water and food. Transpiration mainly occurs through stomata, so “veins: transpiration” is the incorrect match.
- Q6: Spinning is the process in which fibres are drawn out and twisted together to form yarn.
- Q8: The motion is rectilinear because Mini travels along a straight path and periodic because the same journey repeats after equal time intervals.
- Q9: Humans normally have 12 pairs of ribs, so there are 12 ribs on each side of the chest.
Class 6 Science Olympiad FAQs
Is the PDF on this page from SCO Olympiad?
Yes. The downloadable PDF and the practice questions on this page are SCO Olympiad Class 6 Science material retained as a previous-year practice resource.
Can I download the Class 6 Science Olympiad paper for free?
Yes. The embedded PDF can be opened or downloaded from this page for revision and timed practice.
How should students use a previous-year Science Olympiad paper?
Attempt it before checking the answers, record guessed and incorrect questions, revise the related concepts and then retry the difficult questions. Previous-year papers are most useful for finding weak areas and improving speed and accuracy.
Does an older paper always match the current Class 6 syllabus?
No. Textbook structures and Olympiad instructions can change. NCERT now lists the Class VI Science textbook as Curiosity, so students should use this older SCO paper for practice while checking current school topics separately.
Where can I continue with SCO Class 6 Science Olympiad preparation?
Students can continue with SCO International Science Olympiad resources and other Class 6 practice material after reviewing their mistakes from this paper.
