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

In this animated object, learners examine water molecules moving through a semipermeable membrane.

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

Learners examine the do's and don'ts of blogging in a school setting. They compare the features of a student blog with those of a classroom community blog. This learning object is particularly designed for instructors.

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

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

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

In this interactive object, learners solve for the current through each resistor, the voltage across each resistor, and the power dissipated.

In this interactive object, learners identify the symptoms of fluid volume excess and fluid volume deficit.

In this interactive object, the learner practices identifying charges on ions.

In this interactive object, the learner examines the basic terms used in division. A quiz completes the activity.

In this interactive object, learners read an overview of records management and then classify records as "vital," "important," "useful," or "nonessential" in a drag-and-drop exercise.

In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave displayed on an oscilloscope screen.

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

Identifies the parts of the hydraulic press brake featuring the Adira up-acting press brake. Interactive section asks to identify parts after first learning them.

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

In this interactive lesson, learners study examples of nouns that can be counted and nouns that cannot. They then identify whether a word is a "count" or a "noncount" noun in a practice exercise.
