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.
Taffy Atoms
By Eileen Bouchard
Students read brief descriptions of atoms, molecules, elements, and compounds, and complete a matching exercise that pictures these particles and molecules as pieces of taffy.
Calculating Formula Weight and Molecular Weight
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
In this interactive object, learners calculate formula and molecular weights by working through five examples and two problems.
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.
Body Sections and Divisions of the Abdominal Pelvic Cavity
In this animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.
Percent Composition of Compounds (Screencast)
Learners examine the method used to calculate the mass percent of an element in a compound. Three examples and one problem illustrate the method.
Product Yields in Chemical Reactions (Screencast)
Learners examine the meaning of theoretical yield, actual yield, and percent yield. They test their knowledge by solving two problems.
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.
How to Use a Microscope
Learners examine the function of each part of a microscope and follow step-by-step instructions on how to focus on a specimen. They also review the proper use and care of a microscope and test their knowledge in two drag-and-drop exercises.
Dental Charting
The purpose of this learning object is to introduce the dental hygienist to the process of documenting a patient's dentition.

Chemical Bonds: The Hydrogen Bond
By Jill Larson
In this interactive object, students examine a type of chemical bond known as the "hydrogen bond."
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. Check out our video on relative position: https://bit.ly/2kTXujp
What Is Torque? (Screencast)
By Terry Bartelt
Learners read a description of torque and study the factors that cause its magnitude to change.
Acid-Base Reactions (Screencast)
By Dr. Miriam Douglass, Dr. Martin McClinton
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.
