4-H National Youth Science Day 2015

Motion Commotion Experiment Uses Video Physics App

This year’s National Youth Science Day experiment was submitted by Oregon 4-H in collaboration with Oregon State University and Vernier. The experiment, “Motion Commotion,” relates speed, stopping distance, and reaction time. Participants have the option of using the Video Physics app for iOS to analyze the motion of a toy car moving down a ramp and coming to a stop on a level surface.

Since 2008, the National 4-H has held a National Youth Science Day, in which 4-H members across the country do an experiment and learn science outside of their school classrooms.

This year’s National Youth Science Day will be Wednesday, October 7th. To learn more about the 4-H National Youth Science Day, go to
