The expedition’s shrinking memory

What must survive when a briefing becomes shorter?

Make your own investigation

Write your own six-line briefing. Preserve a condition under a word budget and test the resulting answer.

Keep complete lines from the beginning until the budget is exhausted. Report whether declared essential lines survived.

Case cards

Cut these cards apart. Use the original example first, then let a partner supply a changed case. Keep sealed/final cards with the teacher until the learner commits a rule.

Case 1

Briefing line: The walk leaves at nine.

Essential condition: False

My prediction and reason:

Case 2

Briefing line: When it rains the walk is cancelled.

Essential condition: True

My prediction and reason:

Case 3

Briefing line: Bring a water bottle.

Essential condition: False

My prediction and reason:

Case 4

Briefing line: The guide wears a green hat.

Essential condition: False

My prediction and reason:

What this cannot establish

Presence does not prove a model will use a condition correctly. Test the resulting briefing separately.
