Essential question: Why is matter recycled while energy flows?
Open monday Deep Lesson · Model, Worked Example & Practice
Carbon atoms in food can later appear in exhaled carbon dioxide or new biomass.
Build an initial model and explanation for: Why is matter recycled while energy flows?
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: conservation of matter; metabolic pathway; biosynthesis; decomposition.
Open tuesday Deep Lesson · Model, Worked Example & Practice
Study and explain the week's core ideas: conservation of matter; metabolic pathway; biosynthesis; decomposition
Teacher-approved carbon-tracing diagrams.
Revise Monday's model. Add two evidence-backed annotations and explain one limitation or uncertainty.
Open wednesday Deep Lesson · Model, Worked Example & Practice
Complete atom accounting through simplified reactions.
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: Why is matter recycled while energy flows?
Open thursday Deep Lesson · Model, Worked Example & Practice
Carbon-tracing model with cards or digital system model.
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.
Record variables or design constraints, procedure/model, observations/data, and one revision you would make after reviewing the evidence.
Open friday Deep Lesson · Model, Worked Example & Practice
Answer the essential question: Why is matter recycled while energy flows?
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%.
Select one artifact from this week and explain why it is trustworthy evidence of growth.
