The Sense of Smell
By Barbara Liang
In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.
The Sense of Sight (Screencast)
In this screencast, learners read about the parts of the eye.
The Sense of Hearing (Screencast)
In this screencast, 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 Mole and Avogadro's Number
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine how chemists use moles to "count" atoms by weight. Examples are given.
The Limiting Reagent in Chemical Reactions
In this interactive object, learners determine the limiting reagent and the excess reagent in chemical reactions. Learners test their knowledge by solving three problems.
The Kinetic Theory of Gases
By Dr. Miriam Douglass, Dr. Martin McClinton
In this animated activity, learners examine what gases are composed of and how their particles interact. They also consider several assumptions that form the basis for the Kinetic Theory of Gases.
The Juxtaglomerular Apparatus
By Becky Polk-Pohlman
Explore the location, structure, and function of the juxtaglomerular (JG) apparatus.
The Fungi Kingdom: Common Characteristics of Fungi
Learners examine what defines a fungus and read how fungi differ from animals and plants.
The Four Types of Chemical Reactions
In this animated object, learners examine synthesis, decomposition, exchange, and reversible reactions.
The Formation of Ester Bonds in the Synthesis of Lipids
By Richard Wilkosz
In this animated object, learners examine the formation of ester bonds in the synthesis of lipids using triglyceride biosynthesis as an example. Ester bond formation is described as a dehydration synthesis reaction.
The Food Pyramid
By Michele Williams
In this learning activity you'll explore the food pyramid and the recommended services.
The Electrocardiogram (Screencast)
By Bruce Forciea
In this animated object, learners view the "T" and "P" waves and the "QRS complex." A brief quiz completes the activity.
The Effect of Temperature on the Vapor Pressure of a Liquid
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.
The Corticospinal Tracts
In this animated object, learners examine the major descending tracts of the nervous system. A matching exercise completes the activity.
The Combined Gas Law
Learners combine Boyle's Law and Charles's Law to solve for the pressure, volume, and temperature of a gas sample under two sets of conditions.
The Cell: Passive Transport Osmosis (Video)
By Wisc-Online
Explore what passive transport osmosis is and how it moves water through a semipermeable membrane.
The Cell: Passive Transport Osmosis
In this animated object, learners examine water molecules moving through a semipermeable membrane.
The Cell: Passive Transport Diffusion (Video)
Explore what passive transport diffusion is and how it moves water through a membrane.
The Cell: Passive Transport Diffusion
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.
The Cell Cycle
In this animated object, learners examine the different phases of a cell's life.
The Brain - Anatomy and Function
By Susan Heitman
Learners review and reinforce their knowledge of brain anatomy and function in this learning activity.
The Basidiomycetes of the Fungi Kingdom
Learners examine the lifecycle of basidiomycetes. Terminology and fungi examples are provided.
