Scenario
A Year 9 student, Priya, wants to investigate the question "Does music help you study?" Her teacher tells her the question is too vague to test and asks her to refine it before planning anything.
(a) Why is "Does music help you study?" too vague to investigate as it stands? Identify what is missing.
(b) Rewrite the question so it is investigable. Your version must name a variable to change and a variable to measure.
(c) Name two variables Priya would need to keep the same (controlled variables) so her test stays fair.
1. A student plans to test "Does the type of soil affect how tall a gum tree grows?" using real gum trees over a 10-week project. Explain why this question is not feasible, and suggest one change that would make it investigable in the time available.
2. A wellness video claims "celery juice cures anxiety." Rewrite this claim as an investigable question, then state one reason the original claim cannot be tested as written.
