The Anatomy of the Heart (Video)
By Becky Polk-Pohlman
In this video learners view the valves and chambers of the heart.
By Barbara Liang
In this animated activity, learners examine the two major phases of cell division: mitosis and cytokinesis.
The Fungi Kingdom: Common Characteristics of Fungi
Learners examine what defines a fungus and read how fungi differ from animals and plants.
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
In this well-illustrated activity, learners examine the three types of intermolecular forces: dipole-dipole forces, London or Van der Waals forces, and the hydrogen bond. Two interactive questions are included.
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.
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.
Introduction to Class 3 Levers
By James Bourassa, John Rosz
In this interactive object, students view an animated depiction of Class 3 levers. A matching quiz completes the activity.
The definition of an isotope is illustrated using the three isotopes of carbon. The three isotopes of hydrogen are discussed as exceptions.
The Combined Gas Law
By Dr. Miriam Douglass, Dr. Martin McClinton
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.
"I Want to Be Well" Case 1: Respiratory Pathogens
By Dawn Madl
In this learning activity you'll observe information and formulate an evaluation that includes diagnosis and microorganism identification.
Test Your Knowledge of Miscellaneous Bacteria
By Marise Hussey
Learners match diseases with their portals of entry, causative agents, and associated vectors.
Spelling of Bacteria Names
Learners listen to the pronunciation of bacteria names and then type the words. They may choose the number of names that they wish to spell (up to 70). Immediate feedback is given, and a final score is provided at the end of the activity.
Introduction to Safety in the Chemistry Lab
By Bruce Bell
Learners read about lab equipment and basic safety measures. In a quiz, they view photos and determine if the lab technicians pictured are using safe practices.
The Sense of Smell
In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.
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.
Respiratory System Gas Exchange
By Bruce Forciea
In this animated object, learners examine the mechanisms for gas exchange among the lungs, blood, and tissues.
Energy in Chemical Reactions
In this animated and interactive object, learners examine kinetic and potential energy as well as the first law of thermodynamics and the flow of energy between a system and its surroundings. Students also answer questions about exothermic and endothermic reactions
Atomic Symbols, Atomic Numbers, and Mass Numbers
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.
Nervous and Epithelial Tissue
In this colorful, interactive object, learners examine nervous and epithelial tissue composition and function. A quiz completes the activity.
Students solve a molarity problem in a drag and drop exercise.
In this animated activity, learners compare the van der Waals equation with the Ideal Gas Law.
Common Types of Oxidation-Reduction Reactions
