✍️ Short Response — Use Evidence
Explain one way energy moved in this unit and how that energy caused a motion change. Use evidence from a collision, speed test, or surface/friction test.
✂️ PARENT ANSWER KEY — Detach before giving worksheet to students
Parent note: Student wording may vary if the physical-science reasoning is correct.
Multiple-Choice Answer Key
- Energy can move from one object to another in a collision.
- Greater speed often causes a bigger motion change.
- Rough surfaces usually create more friction and slow objects sooner.
- A fair test changes one variable and keeps others the same.
- Evidence should include specific observations or measurements.
- Stopping or slowing after contact is evidence of friction or energy transfer.
- Comparing a low and high ramp helps show how speed changes results.
- A strong explanation connects claim, evidence, and reasoning.
Short Response — What Success Looks Like
- Student names a specific test from the unit.
- Student describes the motion change with evidence.
- Student explains how energy moved or changed during the event.
Short Response — Sample Acceptable Answer
In the collision test, the moving car hit the resting car and the resting car started rolling. That evidence shows energy moved from the first car to the second car and caused a new motion change.
