Essential question: Why do temperature and concentration affect reaction rate?
A reaction speeds up as particles collide more frequently or energetically.
Build an initial model and explanation for: Why do temperature and concentration affect reaction rate?
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: collision; activation energy; temperature; concentration; surface area.
Study and explain the week's core ideas: collision; activation energy; temperature; concentration; surface area
Open collision-theory text.
Revise Monday's model. Add two evidence-backed annotations and explain one limitation or uncertainty.
Compare rate ratios across conditions.
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: Why do temperature and concentration affect reaction rate?
Safe simulation/data analysis; no unsupervised reactive mixtures.
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.
Answer the essential question: Why do temperature and concentration affect reaction rate?
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.
