Learners analyze a base-biased npn transistor circuit. A "help" screen is available.

Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.

In this animated activity, learners study how the magnetic field of an armature can distort the DC motor's main magnetic field. A brief quiz completes the object.

Learners view animations showing how a time-of-flight flowmeter uses ultrasonic sound waves to measure the flow of a liquid.

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.
