The learner will identify active and passive voice and distinguish between the two.

Learners view the operation of an NPN transistor in the active region.

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

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

In this learning activity you'll evaluate the immune response including active, passive, natural, and artificial immunity.

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 will examine the four steps to listen actively to improve relationships.

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

In this learning activity you'll explore the difference between mass and weight.

Multimedia Principles - Signaling. Explore how using voice and visual cues can help your learners focus, organize, and process your content.

In this learning activity you'll review the differences between identification, authentication, and authorization.

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

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.

Students read about the world's active volcanoes that make up the "Ring of Fire." In an interactive exercise, they locate these volcanoes on maps.

In this learning activity you'll use active listening skills to answer 10 questions based on a story.

In this activity you will learn the benefits of SSH, Secure shell, versus plain FTP.

Learners listen to effective techniques to successfully interact with customers via the telephone. They also submit their own suggested replies to customers in various scenarios. Topics include general telephone etiquette, dealing with angry callers, working with confused or unsure customers, and managing voicemail. A quiz completes this customer service activity.

Learners read about the strengths and weaknesses of this Web communication tool.

This activity is cognitive. Learners will actively listen to a story activated by the computer. Then learners will take a quiz on their comprehension. Lastly, learners will compare their chosen answers against the answer key to determine how well they really did "actively" listen. (Credit given to Tom E. Wirkus, University Of Wisconsin-LaCrosse for this activity.)

In this animated object, students observe how ATP energy is used to move substances across the cell membrane from an area of lower concentration to an area of higher concentration and when something too large needs to get in or out of a cell.
