In this animated learning object, students examine the life cycles of a virus.
Virus Particles: Structure and Function
By Kristine Snow
In this learning activity you'll assembles parts of a virus and match virus terms and descriptions.
Virus Matching Exercises
Learners complete two exercises. In the first quiz, they divide viruses into two categories: RNA and DNA. They later match each virus with the disease it causes.
Transport Processes Requiring ATP
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.
In this learning activity you'll review the structure and function of the different tissues of the human body.
In this animated and interactive object, learners examine the lifecycle of fungi including asexual and sexual reproduction. Learners test their knowledge by identifying a diagram and by completing a crossword puzzle.
The Vertebral Column
Learners read a brief description of the vertebral column and examine the distinctive features of the cervical, thoracic, and lumbar vertebrae.
The Vascular System of the Kidneys
By Becky Polk-Pohlman
Learners play a vascular system "game" to identify the arteries, capillaries, and veins that make up the renal blood supply pathway. A score is given at the end of the activity.
The Upper and Lower Motor Neurons
In this animated object, learners examine the function and location of the motor neurons and the damage that can result when they are injured.
The Unipolar and Multipolar Neurons
Learners examine the location, structure, and function of the unipolar and multipolar neurons.
The Two-Neuron Knee-Jerk Reflex Arc
In this interactive object, learners examine the neuron pathway into and out of the spinal cord. They complete the activity by testing their knowledge of vocabulary and the location of spinal cord structures.
The Structure of the Muscle Organ
In this animated object, learners examine the various connective tissue layers of the muscle organ. The terms "prime mover," "synergist," "antagonist," "origin," and "insertion" are defined.
The Stress Response
In this animated object, learners read a brief description of the roles of the hypothalamus, emotions, and adrenal secretions during the stress response.
The Sense of Taste
In this interactive object, learners examine the structure and function of the sense of taste.
The Sense of Smell
In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.
The Sense of Sight (Video)
In this screencast, learners read about the parts of the eye.
The Sense of Sight
In this animated and interactive object, learners read about the parts of the eye. A short quiz completes the activity.
The Sense of Hearing (Video)
In this screencast, learners examine hearing and balance. Detailed drawings of the outer, middle, and inner ear structures are included.
The Sense of Hearing
In this animated activity, learners examine hearing and balance. Detailed drawings of the outer, middle, and inner ear structures are included.
The Plant Kingdom: An Introduction
Learners read about the mutations that occurred in plants for the successful transition from an aquatic to a terrestrial existence. The classification of plants is based on these adaptive structures.
The Organization of the Human Body: Body Cavities
In this interactive object, learners examine the locations of major body cavities and their protective membranes. A drag-and-drop exercise completes the activity.
The Neuromuscular Junction
In this animated object, learners examine the major events that occur at the neuromuscular junction.
The Juxtaglomerular Apparatus
In this animated and interactive object, learners examine the location, structure, and function of the juxtaglomerular (JG) apparatus.
