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

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

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

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.

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

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

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.

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

In this interactive object, learners view the icons and symbols used most frequently in value steam mapping. A matching activity completes the object.

In this interactive object, learners read the definitions of terms associated with the construction of a grouped frequency distribution. A brief quiz completes the activity.

In this interactive object, learners read a description of value-added and non-value-added activities and then place various work duties into these two categories.

In this animated and interactive object, the learner uses a TI-86 calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.

In this interactive object learners will sort veterinary urinary medications into categories.

In this animated and interactive object, learners calculate the area and centroid of a rectangle.

In this interactive object, learners determine the limiting reagent and the excess reagent in chemical reactions. Learners test their knowledge by solving three problems.

In this interactive object, learners read the definitions of the parts of a cell and assemble a basic eukaryotic cell in a drag and drop exercise. A matching quiz involving cell terms and their definitions completes the activity.

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

Learners use the coefficients in a balanced equation to develop the mole ratios of reactants and products involved in the reaction. Five interactive examples illustrate the method, and students test their knowledge by working four problems.
