Active tissues consume oxygen and release carbon dioxide at different rates.
Learning target
Build an initial model and explanation for: How do cells release usable energy from organic molecules?
Evidence task
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: glycolysis; aerobic respiration; ATP; redox; fermentation.
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: How do cells release usable energy from organic molecules?
Respirometry simulation or germinating-seed dataset; avoid sealed living-organism experiments without supervision.
Safety boundary
Use the course safety charter. If supervision, facilities, materials, or conditions are not appropriate, use the supplied-data/simulation alternative rather than improvising hazardous procedures.
Evidence task
Record variables or design constraints, procedure/model, observations/data, and one revision you would make after reviewing the evidence.
Answer the essential question: How do cells release usable energy from organic molecules?
Mastery evidence
Submit a claim, at least two specific pieces of evidence, reasoning that connects them, one limitation/counterclaim, and a correction note for any essential concept below 80%.
Portfolio
Select one artifact from this week and explain why it is trustworthy evidence of growth.
