I'd suggest trying out your local Radioshack for the magnets. I managed to get a five pack for $2.99 haha.

As you may or may not know, we on the national rules committees at Science Olympiad begin work about this time every year on updating the rules for next year. We have a general policy of trying to make at least one significant change to each returning event (not all events return every year - they rotate in and out every so often), as well as trying to correct issues that required clarifications or FAQs.

The day after Nationals we (the national event supervisors, state directors, etc. etc.) always have a big meeting where we hash out issues face to face and try to come up with a near final version of the new rules. While many of us (myself included) are former competitors, in general we don't get direct input from current competitors during this process, although we do get some input from some coaches who happen to be involved at the national level.

Thus, as the Physical Sciences Committee chair, I've decided to try an experiment this year. MagLev is tentatively scheduled to return the following year (2012-2013 season), but will also continue to be a trial event in some states next year (2011-2012 season). What specific changes would you make to the rules? I'm open to all suggestions (small and large), but can't promise we'll actually implement any of them. Feel free to post ideas here or send me a PM if you'd like.

Do you have any idea as to whether New York is likely to run it as a trial again next year? Also, as I suggested on the other thread, elaboration of the content of the test is really necessary. The specs on the Optics test this year are a model - the description was quite thorough, and gave students a clear understanding of what to prepare. The existing spec on the Magnetic Levitation trial rules states, in its entirety, "Basic information on physics of magnetism, common uses of magnets, medical uses of magnets, superconductors." Since the test is weighted at 50% of the event score, this is clearly inadequate. After all there are almost two full pages on the vehicle, which is only 25% of the event score. I also think that the weighting is a bit off - perhaps the vehicle could be 40%, prediction 15%, graphs 5%, test 40% or something like that.

Also, can the size of the track be standard this time, and not just "somewhere in the ballpark of whatever width"? Most teams' problems were the tracks because the rules weren't specific enough. I know it's hard to all order the same type of track, but it would be really great if something was done about the ambiguity of the rules.

Personasaurus Rex is right, there must be something about a exact track size. While our car always ran, it was built to run best on our school's track, which was ever so slightly different from all the competition tracks. We saw many cars get completely stuck, which gave any cars that did make it down the track an unfair advantage. Also, at regionals the track was really two shorter tracks taped together, and almost every car we saw got hindered by this track splice.

That's not really a problem for the rules committee it is a problem of the manufacturer's. All of the major supply companies except Kelvin and Pitsco seem to be selling the same track, which comes in two sections and is supposed to meet Brookhaven specs, but is actually quite variable. Our district ordered three and they were all different widths, the narrowest about 1/16" shy of 2 9/16". Even if the rules committee made a tighter spec, I suspect that there would still be a lot of variation in the competition tracks, because that is the way they come. Honestly, though, principles are simple enough that accommodating the track is about the only challenging aspect of the build.

There should be a rule about he track being in one piece, at least. There was just no reason that the track was in two pieces.

Still, they couldve done better than taping the tracks together.

Which regional was this? And are you sure that the track itself was taped together, or was it just the side rail?

It was literally two shorter tracks, lined up and held in place by two pieces of tape, one on either side. The was a small lip at the joint, and it affected most cars saw that made it that far. A lot of cars didnt make it that far; they didnt move at all because the track was smaller than those teams' school's tracks, which brings us back to the other issue.

Does anyone have any idea on what to use to create a mock sled for the MagLev? I tried foam, but it isn't standing up too well, especially under over 150g weights.
It's the week before the competition... Look forward to seeing all of you at SUNY!

Tupperware. See if you can find one that just fits between the rails, then just position the magnets. Using sand as your weight is a great way to keep it balanced.

I am a new coach for this trial event and need to order the track. I see from the NY site (http://www.newyorkscioly.org/SOPages/COTResources.html) which the MagLev Science Olympiad description points to says that there are both Kelvin and Pitsco tracks but Pitsco moved their magnets.

Who is the manufacture of the tracks which will be at nationals? Does anybody know so I can make sure I order the right ones.

Thanks.

Are rechargeable 9 volt batteries allowed in the MagLev trial event in Wisc? It doesn't state they are not. Thank you!
