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

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

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 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.

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

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

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

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, part 3 in a series, learners follow the steps of the “mathemagician” to examine four numerical curiosities: What’s Special About 1089, Perfect Squares: 1089 and 9801, The Mathematical Significance of 1776, and The Calculator Number Game. The learner will also study six number patterns and look at one remarkable table. Immediate feedback is provided.

In this interactive object, students read about organizing data in a tabular form. A brief quiz completes the activity. This is the first in a series of six learning objects.

In this interactive object, learners examine the structural-functional, social-conflict, and symbolic interaction analyses of recreation. A mind map and quiz questions are included.

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

In this interactive object, learners sort veterinary anti-inflammatory and pain reducing medications into categories. They also complete an exercise involving trade names.

In this interactive object, learners examine the five problem-solving steps of Define, Measure, Analyze, Improve, and Control. Some of the most common measures and tools are listed for each step.

In this interactive object, learners calculate a centroid of a composite area by first creating a chart. A short quiz completes the activity.

In this interactive learning object, learners follow a strategy for identifying specific and general topics to improve their ability to find the main idea of a passage.

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