Measuring the coefficient of friction of a skater on ice part of comPADRE Pedagogic Library:Teaching with Data:Examples
Students use video analysis of ice skaters gliding across the ice to determine the coefficient of friction between the skates and the ice. Materials include instructions and six videos that can be used for analysis.
Determining Measured Values and Uncertainty part of comPADRE Pedagogic Library:Measurement and Uncertainty:Examples
Student practice taking measurements with various instruments and learn to determine the uncertainty of their measured value.
Performing Calculations using Measured Values that Include Uncertainty part of comPADRE Pedagogic Library:Measurement and Uncertainty:Examples
Students measure the density of pennies to determine their composition. Students practice determining measured values that include uncertainty and practice calculations using numbers that include uncertainty.
