In this animated object, learners view molecules as they collide and move between two different solutions. They also observe what happens when the temperature of the solutions is raised or lowered.

Learners examine what defines a fungus and read how fungi differ from animals and plants.

Explore what proteins are, their structure, and their functions.

In this learning activity you'll explore a graphical depiction of a radian for angular measurement.

The learner studies how electrons travel from one atom to the next. Examples demonstrate how voltage is created by the use of a battery or through magnetism. A quiz completes the activity.

In this learning activity you'll determine what happens to current flow in a series circuit when the resistance is changed.

Explore what passive transport diffusion is and how it moves water through a membrane.

In this learning activity you'll read about Robert Maddux's conflict model and then apply what you've learned to an interactive exercise.

In this interactive object, learners review descriptions of various blood collection tube additives. They then test their knowledge by matching the different tubes to their corresponding additives.

Explore what passive transport osmosis is and how it moves water through a semipermeable membrane.

In this learning activity you'll analyze an introduction and determine whether or not it was effective. You'll also gain an understanding of what makes an effective introduction.

In this animated object, students examine what happens when electrons share molecules.

The target audience of this learning object is trigonometry students who have already learned what a radian is and have already derived the key values of the coordinates associated with common radian units, but now need to practice finding those values on the unit circle. The student does not need to know the definition of the six trig functions to do this activity.

Learners read about the most common forms of financial statements including balance sheets, cash flow statements, and profit and loss statements. A brief quiz completes the activity.

In this animated object, learners examine what anxiety is, how it affects people, and ways to manage it.

In this learning activity you'll differentiate between the five contexts affecting communication.

In this animated object, learners examine what happens to lead and cycle times when the batch size is reduced.

Learners examine the psychological and sociological barriers that interfere with clear communication. They select examples of ad hominem fallacy, bandwagon fallacy, emotional appeals, red herrings, irrelevant appeals to authority, suggestibility and conformity, “poisoning the well’, and “shoehorning.” In an interactive exercise, learners identify ways to overcome these barriers.

Learners examine eight different kinds of faulty logic or perception that interfere with critical thinking. They are superstition, ignorance, clustering illusion, false analogies, gambler’s fallacy, irrelevant comparisons, post hoc fallacy, and slippery slope fallacy. In an interactive exercise, learners identify ways to overcome these barriers.

In this animated and interactive lesson, learners examine additive and subtractive color theories.
