In this interactive object, learners follow steps to program and operate the Ercolina Top Bender.

An interactive html page that allows the user to manipulate a Cardioid-like shape generated by lines.

In this simulation, learners follow a series of steps to operate the Marvel Saw PCII in the manual mode. This activity includes a video clip.

In this simulation, learners follow 10 steps to program a job to saw metal. This activity includes a video clip.

In this learning activity you'll interact with the Johari Window to illustrate how willing you are to disclose information.

Learners are asked to control the Adira press brake following the same steps they would if working on the actual machine.

2D and 3D views used to help convey information from a drafter or designer to the welder are provided. This activity will focus on a mounting wedge. A short quiz to test your ability to correctly read this information follows.

In this animated object, learners examine how a gateway server operates.

In this interactive and animated object, students distribute the valence electrons in simple covalent molecules with one central atom. Six rules are followed to show the bonding and nonbonding electrons in Lewis dot structures. The process is well illustrated with eight worked examples and two interactive practice problems.

In this animated and interactive object, learners observe how two, three, or four groups of electrons around the central atom cause the shape of the molecule to be linear, trigonal planar, bent, tetrahedral, or pyramidal. Seven examples and eight interactive questions are provided.

In this interactive object, learners examine how voltages and currents vary in a parallel LC circuit as the applied frequency changes.

In this interactive object, learners sort antihypertensive medications into categories. Descriptions are provided.

In this interactive object, learners experience how the three primary flight controls allow a pilot to determine the motion of the airplane during flight.

In this interactive object, students read how to calculate the blank size for cylinders in a three-roll pinch roller. A calculator is required for the brief quiz that completes the activity.

In this interactive object, learners study the properties of a trapezoid and use a geometric formula to find its perimeter and area.

In this interactive object, learners calculate formula and molecular weights by working through five examples and two problems.

In this animated and interactive object, the learner uses a Casio fx-260 calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.

Students read about the world's active volcanoes that make up the "Ring of Fire." In an interactive exercise, they locate these volcanoes on maps.

In this interactive object, learners follow steps to find phase voltages in a partial three-phase power distribution circuit.
