To identify twelve (12) elements by observing their physical
- The competition consists of three rounds with a time limit
of five minutes per round.
- In the first round, each team will be required to identify
twelve (12) elements by observing their physical properties.
Some of the samples may be in sealed containers. Each team will
submit an element answer sheet at the 5 minute mark.
- The second round is similar to the first except that a written
clue is provided for each element. One additional clue is provided
in the third round.
- Each correct element selection in round one will score one
point. For round two, each correct response gains two points.
In round three, correct answers receive 3 points. There is no

- Element answer sheets will be submitted at the end of each
round. The team may retain a copy of their answers.
- Teams may submit revised answers in succeeding rounds.
- The elements that could be used are:
Mg, Ca, Cr, Mn, Fe, Co, Ni, Pt, Cu, Ag, Au, Zn, Hg, A1, C, Si,
Sn, Pb, N , P, Sb, Bi, 0 , S, H, I, Ne, and Ar.
- The clues given will be based mainly on the properties and

the first clue could be that it was a good conductor of electricity
and the second that is was a coinage metal.
