Session 1 · VOICE: Validate the Problem
Place walk
- 10 minHook: two photos of the same kind of place, one thriving and one struggling. What signs (tohu) tell you which is which? Which signs are living and which are non-living?
- 20 minWalk your chosen place in pairs. Record three things you notice, one thing you wonder, and what you could measure. Photograph one sign that worries you and one that looks healthy.
- 15 minShare wonders. Sort them into three piles: we can test it, we can measure it, or we can only look it up.
- 5 minChoose a class focus question and pin it to the question board.
Session 2 · VOICE: Observe
Observe like a scientist
- 10 minObservation or inference? 'The water is brown' is an observation. 'The water is polluted' is an inference. Sort ten statements from the walk.
- 15 minPractise on a tray of leaf litter or a jar of stream water: describe colour, clarity, smell and temperature, then count every creature you can see.
- 10 minList the biotic (living or once-living) and abiotic (non-living: light, water, temperature, soil) factors at your place.
- 15 minDesign the recording sheet together: what, where, when, how many, units, weather and notes.
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 count or measure.
