In this animated lesson, students view the operation of an electromechanical relay. A brief quiz concludes the activity.

Using the principle of Pascal's Law, the learner will interpret the gauge readings in a hydraulic system to determine when the system is operating properly under various load conditions and when there is a defect.

In this animated learning object, students are introduced to standard procedures, pilot actions, and pilot callouts for C-172 critical phases of flight.

Learners review Ohm's Law and then work 12 problems to help them apply the law to automotive electrical systems. 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.
