Grade 12 · Week 20 · U5
Essential question: Why does where a force is applied matter?
A door opens more easily when pushed farther from the hinge.
Build an initial model and explanation for: Why does where a force is applied matter?
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: torque; lever arm; equilibrium; center of gravity.
Study and explain the week's core ideas: torque; lever arm; equilibrium; center of gravity
Open torque text.
Revise Monday's model. Add two evidence-backed annotations and explain one limitation or uncertainty.
Torque balance calculations.
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: Why does where a force is applied matter?
Safe lever/door-handle force reasoning; avoid loading furniture.
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 does where a force is applied matter?
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.
