30. Fuse wire used in electric circuits is made of a material with a:

High melting point Low melting point High resistance and high melting point Zero resistance

Explanation: Fuse wire has a low melting point so it melts and breaks the circuit during excessive current flow, preventing damage.

SECTION V: Pedagogical Issues in Science Teaching [Questions 41 to 50]

41. Science as a discipline is best characterized by its:

Reliance on tradition and unquestioned beliefs Systematic method of inquiry, observation, and experimentation Fixed and unchangeable set of facts Focus only on memorisation of formulas

Explanation: Science is fundamentally a systematic, evidence-based process of inquiry and experimentation, not a static body of facts.

42. The most effective approach for teaching science concepts at the upper primary level is:

Rote memorisation of definitions Activity-based/inquiry method involving hands-on experiments Only lecture method Copying notes from the blackboard

Explanation: Hands-on, activity-based, inquiry learning helps learners construct and internalise scientific concepts meaningfully.

43. As per NCF 2005, science teaching at the school level should be closely linked with:

Only textbook content The child's everyday life and surrounding experiences Competitive examination patterns Rote learning of scientific laws

Explanation: NCF 2005 emphasizes connecting science education to children's daily life experiences for meaningful learning.

44. The primary purpose of formative assessment in science teaching is to:

Rank students according to marks obtained Provide continuous feedback to improve the teaching-learning process Only prepare year-end report cards Replace all other forms of evaluation

Explanation: Formative assessment is an ongoing process aimed at diagnosing learning gaps and guiding instruction, not merely grading.

45. A key aim of teaching science at the upper primary stage is to develop in learners:

Ability to memorise chemical formulae accurately Scientific temper and process skills Skill in only laboratory apparatus handling Interest only in scoring well in examinations

Explanation: The core aim of science education is fostering scientific temper, curiosity, and process skills like observation and reasoning.

46. To identify misconceptions held by students in science, a teacher should best use a:

Summative test conducted at year end Diagnostic test Oral roll-call Homework checking register

Explanation: Diagnostic tests are specifically designed to identify learning gaps and misconceptions before or during instruction.

47. The constructivist approach to teaching science emphasizes that:

Knowledge is transmitted directly from teacher to learner Learners actively construct knowledge through their own experiences and reasoning Only textbooks are the valid source of knowledge Learning happens solely through memorisation

Explanation: Constructivism holds that learners build their own understanding through active experience rather than passive reception.

48. Remedial teaching in science is provided mainly:

Before starting a new chapter, for all students uniformly After diagnosing specific learning gaps, to help struggling learners overcome difficulties Only to high-achieving students As a complete substitute for regular classroom teaching

Explanation: Remedial teaching targets identified learning gaps in specific students to help them catch up with the class.

49. An important characteristic of the nature of science is that scientific knowledge is:

Absolute and unchangeable once established Tentative, empirical, and open to revision with new evidence Based only on personal opinion Fixed permanently once discovered

Explanation: A defining feature of science is that its knowledge is provisional and evolves as new evidence emerges.

50. Cooperative/group learning strategies in a science classroom mainly help to promote:

Individual competition only Peer learning, collaboration, and shared understanding Rote memorisation in isolation Reduced student interaction

Explanation: Cooperative learning encourages students to work together, share ideas, and build understanding collaboratively.
