In this animated and interactive object, learners follow steps that begin with choosing the correct drive roll and include feeding the electrode wire from the spool to the welding gun.

Learners examine the theory of operation for a combustible gas detector. A brief quiz completes the activity.

The student takes a quiz on identification and operations of an engine lathe.

The learner reads step-by-step work instructions and views a drawing for facing and center drilling on a lathe.

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 water pump 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.
