Updated for 2026–27: This page contains an archived SCO Olympiad Class 7 Science previous-year practice paper with an embedded PDF, 10 practice questions and an answer key. The existing URL is being preserved because it already has Google search history, while the visible content now correctly identifies the resource as SCO Olympiad.
Use this paper to practise science concepts, reasoning, diagrams and application-based questions. For the best result, attempt the questions first, check the answer key afterwards, and then revise the concepts behind every mistake instead of memorising old option letters.
Curriculum relevance note: NCERT’s official Class VII Science learning outcomes include digestion, acids and bases, heat transfer, mirrors and lenses, electric circuits, time period of a simple pendulum and related investigations. These are closely connected to topics appearing in this archived paper, but students should still follow their current school textbook and teacher guidance for the latest chapter sequence.

How to Use This Class 7 Science Olympiad Paper
- Attempt the questions once without checking the answer key.
- Use a timer so you practise both speed and accuracy.
- Mark guessed answers separately from clearly wrong answers.
- Group mistakes into topics such as nutrition, respiration, acids and bases, motion, light, heat, cells and plant reproduction.
- After revision, retry the difficult questions and explain the reasoning in your own words.
Important: this is an archived practice paper. Exam-day instructions, section names, response-sheet rules and scoring can change, so always follow the current SCO Olympiad paper, admit card and official preparation guidance.
1. Choose the correct order of terms that describe the process of nutrition in ruminants.
- Swallowing → partial digestion → chewing of cud → complete digestion
- Chewing of cud → swallowing → partial digestion → complete digestion
- Chewing of cud → swallowing → mixing with digestive juices → digestion
- Swallowing → chewing and mixing → partial digestion → complete digestion
2. Mohit can see a yellow, wiry branch structure twining around the stem and branches of a tree. Can you help him identify the plant?
- Cuscuta
- Algae
- Fungi
- Dodo
3.Which process is explained below?
- Inhalation
- Exhalation
- Respiration
- Both A and B
4.Consider the following statements:
- Both acids and bases change colour of all indicators.
- If an indicator gives a colour change with an acid, it does not give a change with a base.
- If an indicator changes colour with a base, it does not change colour with an acid.
- Change of colour in an acid and a base depends on the type of the indicator.
5. The given figure shows an oscillating pendulum.
Time taken by the bob to move from A to C is t1 and from C to O is t2. The time period of this simple pendulum is ________.
- (t1 + t2)
- 2 (t1 + t2)
- 3 (t1 + t2)
- 4 (t1 + t2)
6. The image formed by a lens is always virtual, erect and smaller in size for an object kept at different positions in front of it. Identify the nature of the lens.
- Concave lens
- Diverging lens
- Convex lens
- Both A and B
7. A circular metal loop is heated at point O as shown in the figure.
- In which direction would heat flow in the loop?
- In which order the pins at points P, Q and R fixed with the help of wax fall if points O, P, Q and R are equidistant from each other?
- (i)-The heat will flow in both the directions i.e. from O to P and O to R.
(ii)- At first the pins at R and P will fall simultaneously followed by the pin at Q.
- (i)-The heat will flow in both the directions i.e. from Q to P and Q to R.
(ii)- At first the pins at R and P will fall simultaneously followed by the pin at Q.
- (i)-The heat will flow in both the directions i.e. from O to P and O to R.
(ii)- At first the pins at Q and P will fall simultaneously followed by the pin at R.
- (i)-The heat will flow in both the directions i.e. from R to P and R to O.
(ii)- At first the pins at R and P will fall simultaneously followed by the pin at Q.

(a) Tartaric acid (i) soap
(b) Calcium hydroxide (ii) curd
(c) Formic acid (iii) tamarind
(d) Sodium hydroxide (iv) ant’s sting
(e) Lactic acid (v) lime water

Quick Explanations for Selected Answers
- Q1: Ruminants first swallow food, it is partly digested, then cud is brought back to the mouth for chewing before digestion is completed.
- Q2: Cuscuta is a yellow, thread-like parasitic plant that coils around a host plant and obtains nutrition from it.
- Q4: Indicator behaviour depends on the indicator used. Different indicators can show different colour changes in acidic and basic solutions.
- Q6: A concave lens is a diverging lens. It forms a virtual, erect and diminished image for real objects placed at different positions, so Both A and B is the correct choice.
- Q7: Heat conducts away from the heated point in both directions around the metal loop; the nearest pins warm and fall before the farther pin.
- Q10: Tartaric acid is commonly associated with tamarind, calcium hydroxide with lime water, formic acid with ant stings, sodium hydroxide with soap making and lactic acid with curd.
Class 7 Science Olympiad FAQs
Is the PDF on this page from SCO Olympiad?
Yes. The downloadable PDF and practice questions on this page are SCO Olympiad Class 7 Science material retained as a previous-year practice resource.
Can I download the Class 7 Science Olympiad paper for free?
Yes. The embedded PDF can be opened or downloaded from this page for revision, timed practice and concept review.
Does this older paper exactly match the current Class 7 school syllabus?
Not necessarily. An archived Olympiad paper can remain useful for concept and reasoning practice, but chapter order and classroom emphasis may change. Students should use their current school textbook and teacher guidance alongside this paper.
How should I analyse mistakes after attempting the paper?
Separate mistakes into concept errors, reading errors and guesses. Revise the weak concept, solve a few similar questions and then retry the original question without looking at the answer.
Where can I continue with SCO Class 7 Science Olympiad preparation?
Students can continue with SCO International Science Olympiad resources after reviewing the mistakes from this paper.
