Free, optional and no return, upload, family information, live-organism work or new materials. Home absence/private response is not an error. An extra is another invitation, not a daily quota. Keep held first responses before any Days 25/30 home or extra discussion.
Day 21
Optional home: Tell or show one food-to-consumer link from a capsule, if you want. It can be a private thought; no return or family fact is needed.
Supplement: Add F3 to a chosen leaf link and explain both arrow points. Do not claim all caterpillar species are eaten.
Day 22
Optional home: Choose a household-free imaginary sign for the arrow key. Explain what it means without a device or recorded voice.
Supplement: Compare E leaves→C with E pollen/nectar/sap→G and give a reason for the distinct labels.
Day 23
Optional home: Describe one difference between a matter loop and energy flow to yourself or a willing person. No observation or experiment at home is asked.
Supplement: Add a carbon dioxide path alongside the mineral-nutrient loop, keeping sunlight on the energy trace.
Day 24
Optional home: Ask yourself what would make a remaining food path useful. Keep an unknown rather than searching a local habitat.
Supplement: Draft a model comparison with sufficient versus insufficient alternatives and an explicit time frame.
Day 25
Optional home: After your first FW-C response, choose a familiar study method for one actual available component. No answer from home is required.
Supplement: After the first response only, compare your assumption with another possibility; mark any teaching help and revision.
Day 26
Optional home: Use a spoken “if … then … because …” about the ordinary model. It need not be shared or written.
Supplement: Add one indirect pathway after more L, and say which other conditions would need to stay similar.
Day 27
Optional home: Notice a certainty word in an invented model claim, such as always. Change it if your source cannot support it.
Supplement: Compare delayed and immediate effects without adding invented counts or a universal timeframe.
Day 28
Optional home: Keep a source ID beside an optional private explanation. No family source, photo or online report access is required.
Supplement: Compare the specific QM F6 link with the general NPWS mammal diet claim; explain why their scopes differ.
Day 29
Optional home: Use your genuinely available explainer for one self-chosen question, or start afresh if it is absent. Sharing is optional.
Supplement: If a willing person really uses it, record an actual question privately and choose a source-based revision; otherwise retain a plan.
Day 30
Optional home: After the first FW-D response, decide whether to keep one component for later study. No grade, home return or proof of improvement is asked.
Supplement: After the first response only, contrast direct and competing indirect pathways; retain uncertainty where it is reasoned.
