Monday

Phenomenon / Launch

The same reaction proceeds at very different rates under different conditions.

Learning target

Build an initial model and explanation for: How do enzymes change reaction pathways without being consumed?

Evidence task

Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: enzyme; active site; activation energy; denaturation; rate.

Tuesday

Concept & Model Revision

Study and explain the week's core ideas: enzyme; active site; activation energy; denaturation; rate

Reading

Open text on enzymes and reaction-energy diagrams.

Evidence task

Revise Monday's model. Add two evidence-backed annotations and explain one limitation or uncertainty.

Wednesday

Data & Quantitative Reasoning

Graph reaction rate against temperature or substrate concentration.

Evidence task

Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: How do enzymes change reaction pathways without being consumed?

Thursday

Investigation / Engineering

Catalase-style dataset analysis or supervised safe simulation; no ingestion.

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.

Friday

CER / Synthesis

Answer the essential question: How do enzymes change reaction pathways without being consumed?

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.
