Introduction to Safety in the Chemistry Lab
By Bruce Bell
Learners read about lab equipment and basic safety measures. In a quiz, they view photos and determine if the lab technicians pictured are using safe practices.
I've never heard of test tube holders, or clamps, referred to as test tube "tongs".
Many of the pictures in the safety quiz were too small to see well enough to really answer the questions. Maybe if there was only one picture per frame?Posted by Mrs. K.Witt on 8/29/2016 11:52:04 PM Reply
