Assess students' ability to design and carry out a fair test investigating how ramp angle affects how far a toy car travels, including writing a testable hypothesis, identifying and controlling variables (same car, surface, release method, starting point), selecting and using measurement tools (protractor, ruler/tape), planning repeated trials, recording and averaging results, creating a distance vs. angle graph, interpreting trends, identifying sources of error, and drawing evidence-based conclusions with basic safety considerations.
