- Source access · 4 min. Release J/K without the key; log read-aloud or other support.
- Independent plan · 5 min. Learner marks shared features, DNA location, complete versus incomplete inventory and one caution.
- Independent response · 7 min. Choose Day 5 route; capture first response with evidence and limit. Do not supply a model sentence with the answer.
- Self-audit · 4 min. Learner checks whether a blank/not-labelled item was treated as biologically absent.
