Engaging in inquiry
During the guided inquiry activity I created an experiment to see if different types of surfaces would affect the momentum of marbles. The one aspect of this inquiry was determining whether the momentum would be different on the hardwood floor. I also used another surface; carpeted floor. I was surprise that the momentum of the marbles on the hardwood floor did not affect the momentum of either size marble. I would have to say this was the one aspect that might have affected my conclusion about whether the size of the marble would make a difference. If I made any modifications it would probably be with other types of surfaces to test. I would make this experiment more real life by using a skateboarder and changing the different types of surfaces to see if that would change their momentum. The one thing I would want students to learn from this experiment is Newton's Laws of motion and how friction would affect the momentum of an object.

Hey guys,
ReplyDeleteI seem to have created two blog accounts? I'm trying to combine or convert my blogs to this account, so if you are a follower of this blog my blog address is http://lcopeland-johnson.blogspot.com
Hello LaKeitha!
ReplyDeleteYour investigation sounds interesting. If I understand correctly, the two different marbles (of different size and mass) had the same momentum on the wood floor. How did the momentum of the same size marble change between the carpeted floor compared to the wood floor? This sounds like a great experiment to try with students, as they could change either the surface or the size/mass of the object.
Thanks for sharing!! :)
This would be a great experiment to use with students when discussing Newton's Laws of Motion and friction and momentum.
