In this animated activity, learners examine the operation of a dynamic braking circuit used to quickly stop a motor.

The student takes a 14-question quiz of shop safety.

In this animated object, learners study how displacement level sensors are used to measure the level of liquid in a tank.

This review assesses the student's knowledge of the tool and cutter grinder and of the tool and cutter grinding process.

This activity is a simulation that allows the learner to practice personal protective equipment tasks.

This activity is a simulation that allows the learner to practice personal protective equipment tasks.

In this simulation activity, an electrician will troubleshoot an AC motor that is overheating. Before accessing blueprints and then using a multimeter to find the fault, the learner will follow safety protocols by following lock-out tag-out procedures and then suit up with appropriate (PPE) personal protection equipment.

In this simulation activity, an electrician troubleshoots a defective compressor motor that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.
