But the kid in the video found a way to compensate. Honestly, I don't know if the data is supposed to be linear or not. Ours turned out to be which made things easier. <br /><br />If the data turned out to be non-intuitive, that possibly could open up for a discussion for what was intuitive and why? The mathematical models usually only take us so far anyway. <br /><br />I'll do the activity again next year, for sure, but I'm going to be prepared for things <i>not</i> to work out so nicely.David Coxhttps://www.blogger.com/profile/06277427735527075341noreply@blogger.comtag:blogger.com,1999:blog-5964889903484807623.post-68900164470909900572010-09-19T11:19:14.734-07:002010-09-19T11:19:14.734-07:00Hey, I tried this with my kids, but it didn't ...Hey, I tried this with my kids, but it didn't go as well as I had hoped. I encountered these problems in my class, and was wondering if you had any suggestions:<br /><br />* cars turning (even smashing into the side when we were doing the "closest to the line" contest). I think this can be fixed in the future by having narrower tracks. (I had built a track for the contest, but it was sort of wide and defeated the purpose.)<br /><br />* The y-intercept for most groups was negative! Why?? The kids felt that was very non-intuitive, and so did I. <br /><br />* Measuring accurately the distances was difficult for most groups, with the cars curving and all. So was releasing it consistently (applying the same pressure) each time. It made me feel that their data was fairly unreliable.<br /><br />Thoughts?? The kids had fun, but I wasn't too happy with the way the math worked out. :(<br /><br />Thanks!<br />Mimiuntilnextstophttps://www.blogger.com/profile/15285583728476473117noreply@blogger.comtag:blogger.com,1999:blog-5964889903484807623.post-66687156019018101622010-08-24T18:37:36.354-07:002010-08-24T18:37:36.354-07:00Sounds fabulous.

Out of curiosity, did the turning radius end up affecting some of the kids' ability to get close to the finish line?untilnextstophttps://www.blogger.com/profile/15285583728476473117noreply@blogger.comtag:blogger.com,1999:blog-5964889903484807623.post-70891941373297278342010-08-23T12:54:48.812-07:002010-08-23T12:54:48.812-07:00Hey, I stole the idea from Frank anyway.
My int...Hey, I stole the idea from Frank anyway. <br /><br />My intuition says it shouldn't be linear either. Maybe it was the cars I bought, the tile floor, user error in measurements or whatever. Either way, it made for a good activity.David Coxhttps://www.blogger.com/profile/06277427735527075341noreply@blogger.comtag:blogger.com,1999:blog-5964889903484807623.post-61465523196960485942010-08-22T09:01:04.632-07:002010-08-22T09:01:04.632-07:00Love it!
