Description: This is a station event. Teams will be given a series of tasks to perform involving measurement or estimation of measurement, such as finding the volume of water in a graduated cylinder, massing an object with a variety of scale types (triple beam, pan balance, spring, etc), measuring the length of an object, finding the diameter of a wheel using a caliper, etc. This list is not all inclusive, the tasks may be completely different. In addition some calculations may also be performed.

Materials: Teams must bring NOTHING.

Event leaders will provide all materials, including station items, the test, writing instruments, etc.

Scoring: High score wins. Points will be awarded according to the accuracy of the estimates or measurements. Ties will be broken using pre-selected tiebreaker stations.
