Session 1 · VOICE: Validate the Problem
Place walk
- 10 minHook: photos of two local places. Which looks healthier, and how could we know?
- 20 minWalk your chosen place. Record three things you notice, one you wonder, and what you could measure.
- 15 minShare wonders. Sort them: can we test it, measure it, or only look it up?
- 5 minChoose a class focus question and write it on the question board.
Session 2 · VOICE: Observe
How scientists record
- 10 minObservation vs inference: 'the water is brown' vs 'the water is polluted'.
- 20 minPractise with a jar of stream or tap water: colour, clarity, smell, temperature, pH.
- 15 minDesign the class recording sheet: what, where, when, units, notes.
- 5 minExit card: one observation and one inference from today.
Getting started
Use a sentence starter: 'I notice… I wonder… I could measure…'.
Stretch
Write two different questions about the same place and explain which is easier to test fairly.
Checkpoint
Each student has a testable question and knows what they will measure.
