This animated lesson shows how pushing a start or stop button on a ladder circuit causes the cylinder of a hydraulic circuit to extend and retract.

Students follow the steps for finding the total impedance for a series-parallel circuit. Several examples are given.

In this animated object, learners examine the procedure used to determine the types of terminals on a single-pole, double-throw switch.

This interactive object is designed to help learners memorize the schematic symbols used in ladder logic diagrams. Learners quiz themselves using electronic flashcards.

Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.

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.

In this animated object, learners examine how the sensory, motor, mixed, and reflex nerves work in the human body.

Students answer five questions concerning magnetism.
