The learner reads an explanation of how to determine lengths for tubing and pipe bending and then performs calculations in an interactive exercise. Two methods for determining angle bends are shown. A calculator is required.
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.
Learners examine the components of the x-ray tubehead, a sealed, heavy metal housing that contains the x-ray tube that produces dental x-rays. This object is designed to help students understand the functions and safety features of the tubehead.
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 read how nanotechnology is creating new jobs in emerging industries while making others obsolete. This colorful and animated activity also looks at the types of products being created through the use of technology and how educational institutions have responded.
In this animated object, learners read about the uses of nanotechnology. The sciences, engineering, electronics, and other disciplines converge in nanotechnology. Examples are given for applications in manufacturing, biomedicine, and environmental science. Concerns about possible environmental effects are discussed.
Dental x-rays are generated in the dental x-ray tube. Through this animated learning object, students will learn the steps in x-ray generation from turning on the x-ray unit to exposing the dental x-ray film.
