In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied. A brief quiz completes the activity.

Learners convert a number from standard form to engineering notation.

In this animated and interactive object, learners examine how a variable voltage is obtained from a variable resistor that is wired as a potentiometer across a fixed DC power supply.

Learners work practice problems to calculate the total resistance of a circuit. Feedback is provided.

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

Learners read an explanation of how the Magnetron Ignition System uses a solid state switching component, a step-up transformer, and magnetism to provide a high voltage spark in a one-cylinder combustion engine.

In this interactive object, students view an animated depiction of Class 1 levers. A matching quiz completes the activity.

In this animated object, learners examine formulas for displacement and velocity ratios. They also view examples and calculate velocity and the velocity ratio.

Learners examine the operation of a proportional control amplifier and the two ways that it is programmed using proportional gain or proportional band. A brief quiz completes the activity.

This game will test classroom rules and behaviour.
