Introduction to Safety in the Chemistry Lab (Video)
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.
Laboratory testing begins with a doctor's order and is followed by specimen collection. In this activity, learners review doctors’ lab orders and select the blood collection tubes required for each patient.
The tubehead is a sealed, heavy metal housing that contains the x-ray tube that produces dental x-rays. This learning object will provide students with practice identifying and labeling the dental x-ray tubehead.
