Learners examine the different types of lines used on a P&ID diagram and the types of connections they represent. They test their knowledge in a matching exercise.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.

In this learning activity you'll observe how switches are used in local area networks to increase data transmission speeds.

Learners review Kirchhoff's Current Law and work six practice problems. Feedback is given.

The learner will identify the steps and proper techniques for installing a wire spool on a welding machine.

In this animated and interactive object, learners examine ABO blood antigens and Rh antigens and their compatibility.

Learners read an explanation of the RL time constant and examine the formula for calculating the instantaneous current value. The current is graphed as it climbs to maximum or drops to zero. Note* In the formulas in this module, the Greek letter epsilon should be the mathematical constant 'e'.

In this learning activity you'll examine how a large computer network is configured.

Learners examine the various classifications of airspace and the requirements to pilot an aircraft there. A quiz completes the activity. This object has sound.

In this scenario, learners put themselves in the place of a safety director at a local company. They watch video of an injury-causing incident and propose changes to company policies and procedures to try to maintain a safe environment.

Learners read how to calculate the full-time equivalent for hours worked by employees. Practice exercises complete the activity.

Learners examine how an electromagnet is formed. Animated illustrations show current running through a coil wrapped around an iron core.

In this animated object, learners examine the situation that occurs when any two links of a mechanism lie in the same plane or on a straight line. Crank-sliders and crank-rockers are shown.

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

Learners are introduced to the maximum power transfer theorem. Examples show the load as it varies and the results are graphed.

Learners view steps to reduce changeover time in a manufacturing operation.

In this learning activity you'll review the historical progression of standards to learn what makes a good standard.

In this video, we’ll go over the necessary steps to square the toolhead on a Bridgeport mill.

This screencast shows how blood droplets are held together by a strong cohesive molecular force that produces surface tension in each drop and on the external force. Surface tension pulls the surface molecules of a liquid toward its interior, decreasing the surface area and causing the liquid to resist penetration.

In this learning activity you'll follow 11 steps to take measurements using a Vernier caliper.

Learners review Kirchhoff's Voltage Law and work six practice problems. Feedback is given.

Learners will examine how to use the SMART principle to make sure a goal is simple, measurable, realistic, timely, and holds people accountable.

In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.

Learners read about the vector diagram for a parallel RL circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.

Learners use this Structured Query Language tutorial to gain an understanding of how a SELECT statement is built. This learning object has audio content.
