In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.

In this interactive object, learners read about the differences between push and pull manufacturing systems. A brief quiz completes the activity.

In this learning activity you'll explore the control panel of a Marvel 460A-PC vertical band saw and learn how to make a simple cut.

In this interactive object, students answer 10 questions covering Ohm's Law and Power Law.

In this interactive object, learners examine the neuron pathway into and out of the spinal cord. They complete the activity by testing their knowledge of vocabulary and the location of spinal cord structures.

In this animated object, learners examine the function and location of the motor neurons and the damage that can result when they are injured.

The learner constructs a nail and identifies the terms relating to the structures of the nail in a matching exercise.

This learning object shows how the shape of a stain defines the angle of impact. In general terms the more circular the stain, the more perpendicular will be the angle at which it struck the surface. The more elliptical the shape of the stain, the more acute the angle will be. With practice and experience, the analyst can recognize the general angle of impact based solely on the shape of the stain.

In this animated object, learners read about hydrostatic pressure and observe how it is used to measure the level of a material in a container.

As Pressure, Volume, Temperature, or number of molecules changes, how does that affect one of the others.
