A Typical Animal Cell (Video)
By Becky Polk-Pohlman
In this video, learners view the parts of an animal cell and its organelles.
Absolute Zero Temperature
By Dr. Miriam Douglass, Dr. Martin McClinton
Learners view illustrations showing the direct dependence of the volume of a gas on temperature and consider the relationship between the Kelvin and Celsius temperature scales.
Learners view several movie clips that demonstrate the use of an indicator to follow the neutralization reaction that occurs when an acid and a base are mixed. Students test their knowledge in a series of questions. Immediate feedback is given.
Acids & Bases
Students read different definitions of "acids" and "bases." In an interactive exercise, they identify if a substance is an acid or a base.
An Overview of Pulmonary and Systemic Circulation
By Wendy Dusek
In this animated and interactive object, learners examine how blood flows through the heart and lungs. A brief quiz completes the activity.
Anatomical Terminology: Body Regions
By Barbara Liang
Students identify the various regions of the human body through drag-and-drop exercises.
Anatomical Terminology: Relative Position Video
Students identify the various regions of the human body through video.
Anatomical Terminology: Relative Position
In this interactive learning activity, learners review the terms used to describe relative position of body parts in order to have a common set of words to describe their position.
Anatomy of the Ear
By Donna Matusewic
The student identifies the anatomical parts of the ear and learns the purpose and function of these parts. A review follows the lesson.
Antigen Presentation: T and B Cell Differentiation
By Carol Parent-Paulson
This learning object demonstrates the process by which antigens are identified, processed, and presented to mediators of the cellular immune system.
Ascending Tract: The Posterior White Columns
In this animated activity, learners view the pathways and functions of the fasciculus gracilis and the fasciculus cuneatus.
Atomic Structure and Ionic Bonding
In this animated object, learners examine the chemistry behind table salt.
Atomic Symbols, Atomic Numbers, and Mass Numbers
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners read definitions of atomic symbols, atomic numbers, and mass numbers and then answer questions about the number of neutrons, protons, and electrons in select elements.
Learners read the definition of atomic weight and obtain the weights of elements by viewing the Periodic Table and charts that list atomic weights by name or symbol.
Balancing Oxidation-Reduction Equations
In this animated activity, learners examine the terms "half-reaction," "oxidizing agent," and "reducing agent" and follow five interactive examples to balance equations for oxidation-reduction reactions. Three problems are provided as a self-check.
Biomolecules - The Lipids
In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.
