Lesson 8: Testing, Evaluation & Data Logging
Duration of Days: 4
Lesson Objective
SWBAT:
Conduct a "Coast-Down Test" to measure rolling resistance.
Log Watt-hour consumption at different speeds to find the "Sweet Spot."
How does a 5 PSI change in tire pressure affect our total range?
What does the data tell us about our gear ratio—is the motor running too hot?
Data Logging, Telemetry, Rolling Resistance, Drag Coefficient, Watt-hour/Mile.
CT-CTE.EDP.A.04 (Test and evaluate); CT-CTE.TRANS.E.21 (Monitoring).
DOK Level: 4 (Extended Thinking)
Students conduct controlled tests to gather performance data.
Misconception: "Testing is just driving for fun."
Correction: It is a scientific experiment requiring written data.
Support: Provide "Testing Log" sheets with specific columns.
Extension: Use cameras to film suspension under load.
The Test Report: A summary of data and three "Tuning Changes" based on findings.
