Essential question: How can velocity change even when speed does not?
Five full lessons, worked graph problems, vocabulary, teacher notes, an offline motion model and public randomized practice. The original daily student evidence journal remains below untouched.
An object turning at constant speed is still accelerating.
Build an initial model and explanation for: How can velocity change even when speed does not?
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: acceleration; velocity; instantaneous; average; vector.
Study and explain the week's core ideas: acceleration; velocity; instantaneous; average; vector
Open kinematics text.
Revise Monday's model. Add two evidence-backed annotations and explain one limitation or uncertainty.
Slope and area relationships on motion graphs.
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: How can velocity change even when speed does not?
Motion-sensor simulation or supplied dataset.
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: How can velocity change even when speed does not?
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.
