In this animated object, students view an explanation of how current, voltage, and the charge on a capacitor of a series RC circuit change during five time constants. A short quiz completes the activity.

Students solve five problems to determine the total impedance of a series-parallel circuit. Immediate feedback is given.

In this screencast, Geometric Dimensioning & Tolerancing: The Feature Control Frame, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information.

Learners view animations showing methods of measuring the pH level of a solution using litmus paper and electronic instruments.

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.

In this interactive object, learners view various components of gears and read descriptions of them. Learners then identify the location of each of these components in a drag-and-drop exercise.

Picture of Adira hydraulic shear's operator's panel with part identification and instructions on how to start and stop the shear as well as setting stroke (cutting length).

Introduces two methods of determining bend allowance; one is simple and is an approximate, the other is more precise. Interactive part has learner calculate bend allowance and blank size.

The learner reads about safety considerations for operating a hydraulic metal shear. Text, graphics and a brief assessment are included.
