Materials Required: Blank Paper, Black Markers, Calculators, White or Blackboard
Activity Time: 30 minutes to 1.5 hours
Concepts Taught: Formula Weight, Stoichiometry

This is merely an activity to reinforce the skills of stoichiometry and computation of formula weight.
Therefore, I do not have objectives. The format of this educational game is similar to The Price is Right.
It starts with 4 students being called at random to the front of the room at a row of desks. They are given
a lengthy formula and a limited amount of time to compute the formula weight. The time must be short or all
the students will have the same answer. They should not be able to use a periodic table, but should depend
on previous knowledge. The student who is closest to the correct formula weight wins this portion of the game.
They get to come up to the front of the room and for a prize which could be anything from a piece of candy
to bonus points, etc., They will complete a stoichiometry problem. Just like in the real show, the "audience"
can help them complete it. They should be given a limited amount of time. If they get it right, then they get
the nice prize! I like to give everyone in the class a little treat afterwards too. This is really not that
different from making the students come to the front of the room and complete a problem, but they will have
so much fun, they won't know they're learning!
