In this animated object, learners examine the mechanisms for gas exchange among the lungs, blood, and tissues.

In this interactive object, students view an animated depiction of Class 3 levers. A matching quiz completes the activity.

Learners consider a variety of business etiquette situations and determine if the response given is appropriate or inappropriate.

Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

In this animated and interactive object, learners examine the formula for horsepower and work practice problems.

Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.

The learner will identify ways to overcome barriers to critical thinking and problem-solving including false memories, personal biases and prejudices, and physical and emotional hindrances.
