Learners read about the different uses of the word "data." They will test themselves on examples of data that is singular, plural, qualitative, quantitative, nominal, ordinal, interval, rational, discrete, or continuous.

In this screencast, you'll observe two vehicles moving across the screen at different rates then describe the motion. Additionally, you'll select the corresponding graphs of distance vs. time, velocity vs. time, and acceleration vs. time for each vehicle.

In this learning activity you'll factor an algebraic expression of the form AX(Squared) + BX + C using the FOIL technique.

In this animated object, learners examine synthesis, decomposition, exchange, and reversible reactions.

In this colorful and interactive object, learners examine the structure and function of muscle and connective tissues. A quiz completes the activity.

Learners review descriptions of 10 personality disorders and then test their knowledge in an interactive softball game.

In this learning activity you'll review information on the neural synapse.

In this learning activity you'll review the five Muslim beliefs.

Learners examine how language can interfere with clear communication. They select examples of ambiguity, assuring expressions, doublespeak euphemisms, jargon, emotive content, false implications, meaningless comparisons, and vagueness. In an interactive exercise, learners identify ways to overcome these barriers.

In this learning activity you'll review physiological noise and complete an activity.

The student reviews primary and secondary groups and takes a short quiz.

In this animated object, learners examine how gas volume varies directly with absolute temperature (K at constant pressure). An example of a sample of gas at two conditions of volume and temperature is used to illustrate the law.

In this interactive object, learners view a mind map of the structural-functional Approaches and quiz themselves about the manifest and latent functions and the dysfunctions of social patterns.

In this learning activity you'll identify correctly formatted MLA citations.

In this animated object, learners examine processes that do not use ATP directly including hydrostatic pressure and facilitated diffusion with carrier proteins.

In this screencast, you will see how the Johari Window works when determining a relationship with someone.

In this interactive object, learners identify charges on ions, write new formulas based on charge, and balance equations using coefficients.

In this screencast, learners categorize different metabolic activities as catabolic or anabolic and follow a glucose molecule through the processes of glycolysis, aerobic respiration, and fermentation.

Learners examine the location, structure, and function of the unipolar and multipolar neurons.

In this learning activity you'll match a scenario to Maslow's Principle of Motivation. You'll understand the differences between each step in the hierarchy.

In this interactive object, learners identify the parts of an animal cell and its organelles.

The learner will identify barriers to critical thinking related to internal and external factors after viewing scenarios.

In this colorful, interactive object, learners examine nervous and epithelial tissue composition and function. A quiz completes the activity.

In this screencast, learners examine the function and location of the motor neurons and the damage that can result when they are injured.

Learners examine how vapor pressure is calculated. The vapor pressure of a liquid increases with increasing temperature. If the heat of vaporization and the vapor pressure at one temperature are known, the vapor pressure at a second temperature can be calculated.
