Thanks very much!
They could have been angered that you only used 2 of their materials (rules require 3).solakmagic wrote:My team took a surprising and disappointing 17th at Regionals this year--we contacted the proctor of the event, who told us we were tiered for not following the directions. Barring anything we forgot to read, the directions commissioned us to perform an experiment testing the effect of stress on a paper clip. Given K'nex, Legos, Lincoln Logs, rubber bands, and paper clips, we pulled 1, 2, 3, 4 (IV) rubber bands a total of 10 cm when attached to the arm of a paper clip, and measured the arm of the paper clip's displacement.
Did we not follow the given directions?
I have the rules as saying the students must use at least two of the materials...XJcwolfyX wrote:They could have been angered that you only used 2 of their materials (rules require 3).solakmagic wrote:My team took a surprising and disappointing 17th at Regionals this year--we contacted the proctor of the event, who told us we were tiered for not following the directions.

However, the ruler SHOULD and usually would count as a third.
The stuff you measure with isn't to be counted in with the materials.XJcwolfyX wrote:They could have been angered that you only used 2 of their materials (rules require 3).solakmagic wrote:My team took a surprising and disappointing 17th at Regionals this year--we contacted the proctor of the event, who told us we were tiered for not following the directions.

Yes, and the provided paper clips and rubber bands were used. Two provided materials.XJcwolfyX wrote:The rules state:
"The students must use at least two of the provided materials to design and conduct an experiment."
2014 Rules, Section 3, Paragraph a, Lines 5-6
If I was judging I would have tiered you.
