Newton's Second Law of Motion - Video
By Kim Ristow
In this learning activity you'll examine force, mass, and acceleration to understand this "Law of Acceleration."
The Actions of Hormones
By Barbara Liang
In this animated object, learners compare the mode of action of steroids with the action of amino acid-based hormones.
Acids & Bases
By Jill Larson
Students read different definitions of "acids" and "bases." In an interactive exercise, they identify if a substance is an acid or a base.
By Debbie McClinton, Dr. Martin McClinton
Students read an explanation of chemical formulas in this animated activity. A quiz completes the object.
Microbial Flora in Body Sites
By Dawn Madl
In an interactive exercise, learners identify the human body sites that harbor a normal resident flora and the sites that are sterile.
By Terry Bartelt
In this animated object, learners examine how thermal energy is transferred by conduction, convection, and radiation. A brief quiz completes the activity.
Conversions in Nursing Math
By Barb Hummel
Learners quiz themselves on the conversion factors within and between the metric, apothecary, and household systems.
Students solve a molarity problem in a drag and drop exercise.
The Structure of an Atom
Students examine atomic structure and the octet rule.
Newton's First Law of Motion - Video
The learner views several animations to study Newton's First Law of Motion, also known as "The Law of Inertia."
The Cell: Passive Transport Osmosis
In this animated object, learners examine water molecules moving through a semipermeable membrane.
Passive Transport: Filtration and Facilitated Diffusion
In this animated object, learners examine processes that do not use ATP directly including hydrostatic pressure and facilitated diffusion with carrier proteins.
The Vertebral Column
Learners read a brief description of the vertebral column and examine the distinctive features of the cervical, thoracic, and lumbar vertebrae.
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine how melting, vaporization, and sublimation require energy input while freezing and condensation release energy.
Ascending Tract: The Posterior White Columns
In this animated activity, learners view the pathways and functions of the fasciculus gracilis and the fasciculus cuneatus.
The Juxtaglomerular Apparatus
By Becky Polk-Pohlman
In this animated and interactive object, learners examine the location, structure, and function of the juxtaglomerular (JG) apparatus.
By Bruce Forciea
In this animated object, learners view the "T" and "P" waves and the "QRS complex." A brief quiz completes the activity.
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.
In this interactive object, students examine how the volume and temperature of an ideal gas relate under conditions of constant pressure and quantity.
Naming Binary Ionic Compounds Containing Variable Oxidation State Cations
Roman numerals are used to identify the charges on metal cations having multiple oxidation states. Five examples are provided for practice.
Naming Compounds Containing Polyatomic Ions
Learners examine a table of common polyatomic ions. Eight examples are provided for practice.
Shapes of Simple Molecules - Part 1
By Dr. Miriam Douglass, Dr. Martin McClinton
In this animated and interactive object, learners observe how two, three, or four groups of electrons around the central atom cause the shape of the molecule to be linear, trigonal planar, bent, tetrahedral, or pyramidal. Seven examples and eight interactive questions are provided.
Mole Ratios in Chemical Equations
Learners use the coefficients in a balanced equation to develop the mole ratios of reactants and products involved in the reaction. Five interactive examples illustrate the method, and students test their knowledge by working four problems.
The Neuromuscular Junction
In this animated object, learners examine the major events that occur at the neuromuscular junction.
Muscle Cell Contraction
In this animated activity, learners examine muscle cell contraction and relaxation and consider the role of calcium ions.
