✓Lesson Snapshot
Student Objective
I can use free-fall data to estimate acceleration due to gravity and evaluate measurement error.
Main Activity
Plan or analyze a drop test using timing, height, and repeated trials.
Deliverable
Free-fall calculation and error notes
Tools / Materials
Notebook, calculator, timer or video option, meter stick/tape measure, data sheet
1ProblemUnderstand the challenge and why it matters.
Gravity affects dropped payloads, landing systems, and many mission tests. Small measurement errors can strongly affect calculated acceleration.
2ConceptLearn the engineering idea or skill.
In free fall, an object accelerates downward due to gravity. Repeated timing and height measurements help estimate acceleration and reveal error.
3ApplyUse the skill in a guided task.
Use drop height and time data to calculate acceleration and compare the result to expected gravitational acceleration.
4DocumentRecord your evidence and decisions.
Record the formula used, calculations, units, percent error if assigned, and sources of error.
5ReviewCheck quality and identify your next step.
Your notes should explain why timing and measurement precision matter in fast events.
