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

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 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.

The student reads about the parts of a pipe/tubing bender and later identifies them in an interactive review.

In this animated activity, learners examine the terms "half-reaction," "oxidizing agent," and "reducing agent" and follow five interactive examples to balance equations for oxidation-reduction reactions. Three problems are provided as a self-check.

In this interactive object, learners simplify ratios and solve problems using proportions. All terms are defined.

Students read about the six theoretical perspectives used to explore psychological events and do an interactive exercise.

In this well-illustrated object, learners examine the structures and properties of the four types of solids: molecular, metallic, ionic, and covalent network. Five interactive questions are provided.

In this interactive object, learners read about words that give information about another word in a sentence. Students also practice placing modifiers in sentences in drag and drop exercises.

In this interactive object, the learner reads a case study and then determines appropriate assessment, planning, and intervention strategies necessary during the detoxification phase.
