Purpose: to identify equipment and laboratory techniques used in chemistry.

Materials: Bunsen burners, glassware, safety glasses, aprons, strikers, graduated cylinder, triple beam balance, thermometer, etc=

Procedure: read handouts at each station and follow directions for practicing each technique.
