A Fermi question is one where a seemingly
impossible-to-calculate answer is estimated. A famous
example of a Fermi question is "How many licks does it take
to get to the center of a tootsie roll pop?", where there is
very little data to use and assumptions must be made. Fermi
questions are named after Enrico Fermi, a physicist who is
known for solving these types of questions.
<br /><br />
In Science Olympiad, answers to Fermi questions are given in
powers of ten. For example, an estimated answer to the above
question of 400 licks is put in scientific notation as
4⋅10<sup>2</sup>, and the exponent on the ten is used as the
answer, yielding 2. If the estimate was 600 licks, or
6⋅10<sup>2</sup>, then the answer would be 3, rounding up.
<br /><br />
Points are usually given as follows:
<br /><br />
5 points for the correct power of ten
<br />
3 points for one away from the correct power of ten
<br />
1 point for two away from the correct power of ten
<br /><br />
For example, if the correct answer to the number of licks to
the center of a tootsie roll pop is 2, and the given answer
is 2 , five points are awarded. If the given answer is 3 or
1 , 3 points are awarded, and if the given answer is 4 or 0,
one point is awarded. All other answers would receive 0
points.
