Which one of the following can best develop the spirit of enquiry and…

Students practise asking meaningful questions, forming and refining hypotheses, and testing them.

Sustained projects develop research-based thinking, data collection and analysis skills.

Students gain awareness of cause–effect relationships and scientific reasoning through repeated trials and reflection.

Comparison with other approaches: Parent teacher associations support school–home links and awareness but do not directly provide students with sustained investigative practice.

In-service programmes strengthen teachers and can promote inquiry methods, but their effect on students depends on classroom implementation.

Hobby clubs encourage exploration and creativity but usually lack the structured, long-term experimental design needed for deep scientific enquiry unless specifically organised as investigative projects.

Practical suggestions to maximise impact: Design semester- or year-long science projects where students collect data, review literature, and present findings.

Provide teacher guidance on inquiry methods so experiments are structured for learning outcomes.

Share results through school exhibitions or science fairs to build awareness and reflective skills.
