Day 55: Falling Rolls Class of 2015

AP Physics C: Falling Rolls Day! Here’s video from 2 of this year’s groups. We had some synchronization issues for their first drops, but they each nailed it on their second attempt:

NGSS Science and Engineering Practices:
#2. Developing and using models
#5. Using mathematics and computational thinking

UPDATE: 2014 DEC 4

Physics teacher Dan Hosey shared his class’s results today. I like how they use rods to drop both rolls simultaneously!

    I love this activity (and first learned about it from you!). Here’s my question: with you having it done it so often, are the students less surprised? Are there things in your teaching that you like to be surprises (and therefore take steps to ensure it)?

    • Frank Noschese says :

      It’s amazing how little information gets passed on from one year’s students to the next. This lab, the shoot for your grade lab from last week, tug of war, etc, never fail to surprise the kids. I guess I’m lucky that way. But even if they’d seen it before, it’s physics! Students always love doing it themselves, live and in person.
