Ramp Height and Distance: Finding a Line

Roll a toy car down ramps of different heights, graph the data, and find the slope of the line.

Grade 8Math ChallengeExperimentScience OlympiadMathSciencePhysicsData AnalysisMeasurementIntermediate60 to 90 min7 materials

What you'll learn

  • Make a scatter plot and draw a best-fit line
  • Calculate and interpret the slope as a rate of change
  • Use the line to predict a value you did not test

Objective

Collect data on how ramp height affects how far a car travels, graph it, and interpret the slope of the best-fit line.
