In this interactive object, learners examine the characteristics of osteoarthritis, rheumatoid arthritis, and osteoporosis. Students then describe the precautions to be aware of when working with clients who have arthritis and identify assistive devices that clients might use to prevent injuries at home.

Students complete a sample exam for DC/AC I. It provides an overview of the material presented in the course.

In this interactive object, learners review case studies and identify complex arterial blood gases.

Learners read an introduction to arterial blood gasses and then identify uncompensated ABGs.

Students read and test themselves on the conditions that cause specific acid/base imbalances.

In this interactive object, learners answer 25 questions regarding part or assembly drawings. The basic areas of blueprint reading are covered.

In this animated object, learners examine the relationship between pressure and temperature in an air conditioning system.

By the end of this module, you’ll be able to:

- List four categories of disease agent sources

- Discover conditions when disease transmission is likely to occur

- Describe the means of disease transmission in a given situation

In this animated object, learners examine the factors that determine how well a capacitive proximity sensor can detect an object. Those factors include size, position, and the materials from which the target is made. A brief quiz completes the activity.

In this interactive object, learners examine problem areas related to patients with arthritic conditions. They also identify treatment precautions and design a treatment plan.

In this interactive object, learners identify the risk factors and the precautions to follow when treating a patient with a cardiac condition. They also design a treatment plan for that patient.

Learners read about the process of dividing industrial goods into the categories of entering, foundation, and facilitating.

In this learning activity you'll review conditional sentences and match the "if clause" with the correct "result clause."

In this animated activity, learners examine why various materials are conductors, insulators, or resistors of current. A short quiz completes the learning object.

In this animated, audio and graphic activity illustration, learners will view design criteria for properly storing property and evidence.

Learners will be able to identify areas within the property room including adjoining work areas, work flow, temporary storage, long-term storage, high profile items, bulk or oversize items, biohazards, hazardous materials, cold storage, administrative area, and release areas.

This learning activity presents information on how the type of material used for the dielectric of a capacitor affects the capacitor's value in farads.

Students will learn how to document bloodstains using roadmapping equipment materials

Students view information taken from various sources and decide if the material is acceptable for a technical research report. After choosing whether or not the source material is acceptable, the students read an explanation from the instructor.

In this animated activity, learners examine how to change the gain of an optical sensor to overcome environmental conditions and distance.

Boyle's Law states that gas volume varies inversely with the pressure at constant temperature and is described by the equation PV = constant. An example of a sample of gas at two conditions of P and V is used to illustrate the law.
