Review for:Vernier Motion SensorIf you used this resource in your own classroom, please add your review. posted: on June 1, 2007 at 9:52AM
My rating of this resource: *****
My experience using this resource: physics
Topic I was teaching: uniformly accelerated motion; conservation of energy
My learning goal for which this resource was used: obtain a good data set for an object in freefall; analyze graphs of position and velocity vs. time to determine value of gavitational acceleration; use data to construct graphs of PE/KE/total mechanical energy and attempt to verify energy conservation
Course Level: Honors or Advanced, Intro or Regular
How I/my students used the resource: working in pairs, students used the motion detector and Logger Pro to record data for a soccer ball or basketball that was thrown upward and allowed to fall back toward the detector; data was exported as a text file which students then imported in Excel for graphing and analysis
Value Added: Increases data collection & analysis skills, Provides assessment opportunity
Strengths: The data sets are extensive and high quality; learning the software is quick enough that students can easily collect good data in the time available to them
Weaknesses: motion detectors can produce spurious readings, so it sometimes takes multiple attempts to get good data (on the other hand, that's life in science, so maybe that's not a bad thing...)
