Different organisms or tissues produce distinct gas, heat, or mass-change patterns.
Learning target
Build an initial model and explanation for: How do scientists infer metabolic processes from indirect measurements?
Evidence task
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: rate; control; respiration proxy; confounding variable; uncertainty.
Calculate rates, normalize by mass, and compare variability.
Evidence task
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: How do scientists infer metabolic processes from indirect measurements?
Analyze a supplied metabolic dataset; design a safe follow-up investigation.
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 scientists infer metabolic processes from indirect measurements?
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.
