Did this happen to anyone else? After we estimated we had to measure. About 60 of our points were from measuring and we got 12 points on estimation. I think it just comes down to who did just a couple points better estimation wise.

Yup, estimation is HARD. Our team did well but we didn't get the results so we can't confirm that they estimated well or not. Or measured well or not...

When I first read the rules I thought that it would be easier to get estimation points than it really is! Many of our estimations, even this late in the season, score zeros.

You got your scores? I didn't get my scores for anything, ever. ._.

Ugh, I guess that's what I have to study.

funny... we had the exact opposite situation. Measuring tools must really hate us or something because most of our points came from estimating. We're so unskilled that we're epicly skilled. Or we just have awful luck. :|

In the rules, it says that time is one of the units that could be in competition. So far, I have never seen a competition with this. Can someone give me an example of a time question that might pop up?

Estimate the time it takes for (given object) to fall (given distance).

For example, a 1cm cube falling 2 meters. This question was at the Bay Area Regionals.

That's probably because time is, along with temperature, harder to prepare activities for. I've been stretched to find things, myself. A few ideas...
-as said above, time for an object to fall
-time for some machine to work, turn, or do its thing (you'd see the parts in order to estimate)
-time for a reaction to run to completion
...stuff like that.

From my experience, this is the general trend at both competitive and relatively noncompetitive tournaments.

I ran this event for the second time this season yesterday, and my general warning to all teams now is twofold. First, so many teams are clueless about how to measure to the first uncertain digit. Not doing so cripples your score. Additionally, not coming prepared for estimations is equally dangerous. Practice ballparking common objects in different units. In other words, know the approximate mass of a typical soup can in g, kg, and mg. I'd start there.

At regionals this weekend, there were about 5 mass/weight questions on the test, and as it is said in the rules, you aren't allowed to lift anything without permission (which was not granted). Without the density or volume of the object, how are you supposed to estimate mass w/out touching the object?? :?

When I ran this event I included a station where it was required to measure the period of a pendulum with a stop watch and a station where it was required to measure the length of time for an animated gif to run. The period of a pendulum is constant independent of how high it is swinging. If you are asked to measure a period, remember, it is the time for a full cycle, back and forth.The best way to measure it accurately is to find the time for 10 cycles to complete and then divide the time for 10 cycles by 10.

274-what were the objects? If they were common, then there is your answer. It's not unreasonable to give you a softball, not permit you to touch it, and expect you to estimate mass. THat's part of preparing.

Droobles-that is an interesting take on it! I've given pendulums as instruments (the kids who hate me for this one have Chalker on the first page to thank), never the thing actually being measured. Very cool.

There were some reasonable ones (fishing weight, rock) but there was also one where there was a long metal rod made of an unknown material. Without knowing the metal, it was very hard to estimate.

I think we had something similar. Your best chance is just random guessing at that point. I don't think that the event supervisors will be able to get a hold of a super light or super dense metal, so you should at least get partial points there by just assuming that it is iron or steel or some other common metal.

Well, among common metals you have things like iron and aluminum, which have respective densities of 7.87 g/ml and 2.7 g/ml, so I think so far randomly guessing is our best strategy for this.

2nd: Can I please have tips.

Thanks
