We launched air powered rockets today as the start of our kinematics project. Stage I asks the kids to measure the launch velocity (using video analysis) and predict the max altitude. Kids then compare that prediction to the height they measured using an altitude tracker. Here’s my launch video:
And my video analysis results:
I’m impressed at how quickly these kids learned video analysis. Today’s just the 2nd or 3rd time they’ve used Logger Pro and they needed no help from me — not even remembering to scale the video, something my regular year kids always forget how to do.
During the regular year, this is a great two-period project or lab. Here are the materials you need:
- Air Rocket (Arbor Science)
- Altitude Tracker (Estes)
- Bicycle pump
- Video camera
- Logger Pro or Tracker video analysis software
Get my version of the project. We finish the project on Friday.
