Description
Teams of two students will use various devices to make numerous estimates and measurements expressing their answers in metric units.

Number of Participants
2 students

The Competition
1. Each team of two students will move through stations twice, first time for 30 seconds to estimate and second time for approx. 1 ½ minutes to make actual measurement. Each station will contain the equipment and materials needed to make a measurement or measurements or a set of questions. Students may be quizzed on the various units of the metric system and the conversion among prefixes (100,000 cm = 1 km, for example).
2. All measurements will be made and recorded in metric untis. Students are expected to record all digits know with certainty and one estimated digit (Law of Significant Figures). Simple calculations may be necessary to determine the answers at some stations. Calculators will be provided (no outside calculators allowed).
3. Teams will have a limited amount of time at each station (30 sec first time and 1 ½ minutes the second time). Students must move at the indicated time to ensure that all teams have an equal opportunity to use the equipment at each location.
4. An answer sheet will be provided for each team to record their estimates. A second answer sheet will be provided when teams transition to the actual measurements.

Scoring
The scoring of the event will be based on the closeness of the estimates and the number of correct responses. Ties will be broken with the closeness of estimates and correctness of responses on pre-determined tie-breaker questions.
