Learners read how to use a lumber rule to quickly and accurately estimate board feet. They then use virtual samples to practice the process.

In this learning activity, learners review the value of health and wellness as it relates to exercise, nutrition, intimacy, and spirituality. Examples of each are identified, and learners are given the opportunity to reflect on how these examples are associated with health concerns in older adults.

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.

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.
