In this interactive object, learners check their knowledge of concepts related to the cost of ensuring quality in manufacturing as they relate to the categories of appraisal, prevention, internal failures, and external failures.

Learners examine the changes in current and voltage values in a parallel circuit when open and short conditions develop. Ohm's Law calculations are shown, and a brief quiz completes the activity.

In this animated and interactive object, learners examine the definitions and formulas for radius, diameter, circumference, and area. Students also solve practice problems involving the circumference and area of a circle.

Examining the Free Exercise Clause of the First Amendment

In this learning activity you'll read about efforts to prevent the government from interfering with citizens' rights to practice their religious beliefs.
