Nature & Structure of Science

The single biggest idea CTET tests in this section is that science has two faces. Science as a PRODUCT is the accumulated body of knowledge — the facts, concepts, principles, laws and theories printed in the textbook. Science as a PROCESS is the way that knowledge is generated — observing carefully, asking questions, framing a hypothesis, experimenting, collecting evidence and drawing reasoned conclusions. Good science teaching gives weight to BOTH; teaching only the product (dictating facts to be memorised) misrepresents what science actually is. Underpinning the process is the scientific attitude — curiosity, open-mindedness, honesty, objectivity and the habit of suspending judgement until there is evidence — and the wider scientific temper, which is reasoning over blind belief and the refusal to accept claims without proof. Science is also self-correcting and tentative: conclusions are always open to revision in the light of new evidence, which is exactly why a child's questions and even wrong guesses are valuable in the science classroom.

✅ Solved examples

1. When CTET describes science as both a "body of knowledge" and a "way of investigating", it is distinguishing science as a:
Product (the organised knowledge) versus a process (the method of inquiry). Sound science teaching addresses both, not the product alone.
2. A teacher encourages students to question results, demand evidence and not accept a claim merely because the textbook says so. She is mainly fostering:
Scientific temper / scientific attitude — reasoning on the basis of evidence rather than blind belief or authority.
3. The statement "scientific conclusions are always open to revision in the light of new evidence" describes which feature of science?
Science is tentative and self-correcting — knowledge is provisional and changes as better evidence appears, not fixed and final.
4. A pupil insists his result is correct even though it does not match the evidence he gathered. The scientific attitude he most needs to develop is:
Objectivity / open-mindedness — judging on the basis of evidence and being willing to revise a belief, rather than clinging to a prior opinion.

✏️ Practice — try these, take hints as needed

1. Treating science only as a set of facts to be memorised ignores which essential aspect of science?
Science has two faces.
How knowledge is generated.
Science as a process / method of inquiry
2. Curiosity, honesty, open-mindedness and reliance on evidence together make up the:
A disposition, not content.
Required for doing science.
Scientific attitude
3. Rejecting superstition and demanding proof before accepting a claim is an expression of:
Reasoning over blind belief.
A national-policy phrase.
Scientific temper
4. That a theory can be revised when fresh evidence contradicts it shows science is:
Not final or absolute.
Corrects its own errors.
Tentative and self-correcting
