This primer introduces the student to the key terms and concepts associated with the silicon diode.

In this animated and interactive object, learners examine why the voltage produced by an AC drive must be increased when its frequency is increased due to inductive reactance.

Learners examine how a linear displacement transducer is used to measure the linear position of a physical object. Animations show the sequential steps of the entire operation.

Learners solve word problems involving basic mechanical principles such as torque, horsepower, work, and power. Students who have problems with a particular word problem may try it again with a different set of numbers.

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.

Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.

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

In this interactive object, students view an animated depiction of Class 3 levers. A matching quiz completes the activity.

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

These are 3rd grade questions on forces & motion for a pretest or post test.

This is totally not a Science project

The students will review key ideas related to gravity.
