✂️ PARENT ANSWER KEY — Detach before giving worksheet to students
Parent note: Student wording may vary if the science reasoning is correct.
Multiple-Choice Answer Key
- Students will compare balanced and unbalanced forces and explain how they affect an object’s motion.
- Students will gather evidence that gravity pulls objects toward Earth.
- Students will test how ramp steepness changes motion and explain the role of gravity.
- Students will observe how a moving object can transfer motion during a collision.
- Students will test how adding mass can change an object’s motion in a force investigation.
- Students will design, test, and improve a small force-based system and defend the improvements with evidence.
- Using evidence from observations, tests, or models to support explanations
- To make system relationships easier to see and explain
Short Response — What Success Looks Like
- Student names a specific investigation from the unit.
- Student identifies the force or force pattern correctly.
- Student uses observations or measurements as evidence.
Short Response — Sample Acceptable Answer
“In the ramp lesson, the toy car sped up when it rolled down the steeper ramp. Gravity pulled it down the ramp, and the unbalanced force changed its motion because the car went faster and farther.”
