By Wendy Dusek
In this highly animated and colorful object, learners examine the steps of carbohydrate digestion. A brief quiz completes the activity.
Conversion Between Mass and Moles of an Element
By Dr. Miriam Douglass, Dr. Martin McClinton
Atomic weights are used to convert the mass of a sample into the number of moles of the element in the sample and vice versa. Four examples are provided for practice.
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.
Anatomical Terminology: Relative Position
By Barbara Liang
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 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.
Naming Binary Ionic Compounds Containing Fixed Oxidation State Cations
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine a table containing the names of common cations and anions. They then check their knowledge by answering a series of questions.
Peptide Bond Formation
By Richard Wilkosz
In this animated object, learners examine the formation of peptide bonds through dehydration synthesis.
Newton's First Law of Motion - Video
By Kim Ristow
The learner views several animations to study Newton's First Law of Motion, also known as "The Law of Inertia."
The Formation of Ester Bonds in the Synthesis of Lipids
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.
What Is Torque?
By Terry Bartelt
Learners read a description of torque and study the factors that cause its magnitude to change. A brief quiz completes the activity.
The Mole and Avogadro's Number
Learners examine how chemists use moles to "count" atoms by weight. Examples are given.
By Bruce Forciea
In this animated object, learners view the "T" and "P" waves and the "QRS complex." A brief quiz completes the activity.
In this animated activity, learners examine the two major phases of cell division: mitosis and cytokinesis.
White Blood Cells
In this animated and interactive object, learners examine the structure and functions of granulocytes and agranulocytes. Two exercises complete the activity.
The Actions of Hormones
In this animated object, learners compare the mode of action of steroids with the action of amino acid-based hormones.
Regional Body Parts
By Gerald Heins
In this interactive object, learners identify a person's regional body parts.
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 Structure of an Atom
By Jill Larson
Students examine atomic structure and the octet rule.
By Elizabeth Yoon
In this interactive object, learners categorize different metabolic activities as catabolic or anabolic and follow a glucose molecule through the processes of glycolysis, aerobic respiration, and fermentation.
The Sense of Smell
In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.
By Kristine Snow
Learners read about endospores and view video clips demonstrating spore staining procedures. Correctly stained slides are shown. The learning object includes two matching exercises.
Science Lab Equipment- Part 1
By Bruce Bell
Students read an introduction to the lab equipment used to contain and dispense chemicals. A quiz completes the activity.
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.
Newton's First Law of Motion
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.
