||To make measurements after estimating the length or circumference
of various objects
||To demonstrate that perception and measurement may differ, and to
improve the participants' powers of estimation
||Any number of individuals or teams.
|| Items to estimate and measure measuring tools (hard and soft rulers)
||Each team or individual will be presented with objects to estimate.
- Teams will have 10 minutes to study the objects, estimate the
dimensions and record them. This record is then submitted to the
- Teams will then measure the object, being as accurate as possible.
- Judges will calculate the difference between the measured and
estimated values, first checking that the measured values correspond
to the values obtained earlier by the judges.
- The team with the smallest overall difference between the actual
and estimated values will be declared the winner.
||Similar experiments can be performed by estimating and measuring
the volume of irregular solids.
