Essential question: How does a reference frame change how motion is described?
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.
A passenger can be at rest relative to a train and moving relative to the ground.
Build an initial model and explanation for: How does a reference frame change how motion is described?
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: position; displacement; distance; velocity; reference frame.
Study and explain the week's core ideas: position; displacement; distance; velocity; reference frame
Open mechanics text on kinematics.
Revise Monday's model. Add two evidence-backed annotations and explain one limitation or uncertainty.
Slope of position-time graph.
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: How does a reference frame change how motion is described?
Walking-motion graph or video analysis in a clear safe space.
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 does a reference frame change how motion is described?
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.
