Weighing and Measuring Techniques

This unit presents material related to weighing and measuring techniques commonly performed in laboratories. It begins by describing the operation of two types of instruments used to make mass measurements: mechanical and electronic balances. Then the techniques of reading various volumetric measuring devices (including graduated cylinders, pipettes, and burettes) are demonstrated. Next, the unit presents demonstrations of how to make linear measurements using calipers and a measuring microscope. The unit concludes with a segment on temperature measurements that describes the techniques used to read alcohol and mercury thermometers and to check the accuracy of liquid-filled thermometers
