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.
Learners examine the labeling scheme used in ladder logic diagrams to identify components, wires, rungs, and rails. This activity includes self-check questions.
Learners examine a CBC and study the functions of blood cells, the normal range for each item on the CBC, and possible reasons for increases or decreases from the normal range.
In this interactive object, learners read the characteristics of each stage of labor and delivery. They then identify the stages in a multiple-choice assessment.
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.
In this animated object, learners examine the method of interpreting the truth tables for two-position and three-position selector switches on ladder logic circuit diagrams.
