Measurement

PHY 100 & 103

Introduces various techniques for making precision measurements that will be used throughout the course. Direct measurements of the mass and dimensions of solid objects allow students to calculate volumes and finally densities. The diffences in making similar assessments of a liquid sample are also addressed, along with the uncertainty inherent in all measurements. Students are instructed in the careful use of instruments such as the meter stick, dial caliper, graduated cylinder, and three types of balances as to illustrate differences in precision.

Equipment

Notes

There should be meter sticks and rulers on the conduiters next to every lab table. Also, the metal cube and metal cylinder should be of the same type of metal.

There are two versions of this lab - "Measurement techniques for mass, size, and density" and "Measurement techniques for mass and size". The orange 1000 cc cube should be placed on the instructors table, and the cubic meter stick model should be assembled and placed at the front of the room, along with any large matter model. Make sure that the room has plenty of paper and that each table has a SAFE-T ruler and a meter stick.
