Evidence Detective

What your child will figure out
- Separate direct observations from inferences about what may have happened.
- Name the visible limit of a magnifier, audio recording, or short time window.
- Use repeated, reliable samples rather than one dramatic noisy clue to calibrate confidence.
- Rate a source and revise confidence when stronger contradictory evidence appears.
The levels
- Desk sandbox
Inspect one scene with three bounded tools and read each explicit limitation.
- See it or infer it?
Sort scene cards into observation and inference spaces.
- One clue is not enough
Compare repeated clear samples with one dramatic blurry frame.
- Surprise revision
Rate a limited source, set initial confidence, then revise after stronger evidence.
Ready when they are.
