DawnL Posted September 15, 2012 Share Posted September 15, 2012 My daughter is gearing up to work on her 3rd science fair project. I posted previously how she didn't do as well as she anticipated in her last science fair and she was very discouraged. I promised her I'd help her "bring her A+ game" so she can produce a high quality project. We've gone back and forth on what her project this year should be. She hadn't come up with anything and everything she considered stemmed from my suggestions so her heart wasn't in it. Suddenly, she came up with her own. She was hesitant to suggest it, mostly because last year's project was an overdone topic and not really relevant. Last year her project was testing which was more electric, fruits or vegetables. She did well, but only received an honorable mention. I understood why, but not until after everything. Her consideration is, can a fully grown person really climb up a tower using human hair? You know, the whole Rapunzel thing. I think this is an interesting question and I told her that as she writes this up she needs to make sure that she not only includes all the scientific verbage that is relevant, but to also discuss how her research and results can be useful. She isn't sure her topic can be useful. I think it can be useful, although I'm thinking perhaps more as a physics question. Such as, if one hair holds Xoz and another holds Yoz, do they together hold Xoxz+Yoz or do they hold Zoz? She is correct when she tells me that no one is going to be using human hair to climb with, but I told her that it could be relevant somehow for mountain climbers. They may not be using human hair, but they certainly could use information about the strength of what they are using. We also discussed the variation....does the color of the hair affect the strength? Does the age of the person with the hair affect how much weight it can hold? If the hair has been chemically altered (colored, permed, straightened, etc) does that effect how much weight it can hold? Another consideration we discussed was, if we tied the hair around something to test how much weight it could lift, it could likely lift more because it is wrapped around the object more than once. So it would be a more accurate test to have the weight tied to some kind of clamp, then clamp the weight to the hair, much like a hand would clamp around the hair. I'm mostly thinking out loud here, but I'd love any suggestions or opinions. I do not want to fail my daughter by not adequately preparing her for the challenge of her next science fair. She was starting to say she shouldn't do it this year, but I wouldn't let her chicken out. I don't want to build her up to fail spectacularly. Our state science fair grades each participant on their own project. If every child in a grade did an A+ project, they could all earn a 1st place position. I doubt that's ever happened as the judging is truly fair, but it gives you an idea of what she could potentially achieve. Now that she is in 6th grade, as a Middle Schooler there are secondary contests as part of the Science Fair, too. I have told her that they are difficult to win so she shouldn't count on those, but we discussed it as a goal to work for. She would consider that an ultimate achievement.
