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."
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 Axial Skeleton: The Skull and the Rib Cage
By Barbara Liang
In this animated object, learners examine the eight cranial bones, the fourteen facial bones, and the ribs.
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 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.
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.
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.
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.
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.
Construction of the Cell Membrane (Video)
In this video you'll study the structure of the cell membrane and construct it using the correct molecules.
Biomolecules - The Lipids
In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.
Calculation of Atomic Weight from Isotopic Composition
Learners examine the method for calculating the atomic weight of copper from the natural percent composition of each of its two isotopes.
Measuring Volume Using a Graduated Cylinder
By Jill Crowder
Learners view an explanation of how to read a graduated cylinder by measuring the lowest portion of the meniscus. A quiz completes the activity.
By Wendy Dusek
In this highly animated and colorful object, learners examine the steps of carbohydrate digestion. A brief quiz completes the activity.
Newton's First Law of Motion
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.
The Actions of Hormones
In this animated object, learners compare the mode of action of steroids with the action of amino acid-based hormones.
The Fungi Kingdom: Common Characteristics of Fungi
Learners examine what defines a fungus and read how fungi differ from animals and plants.
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 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.
Protein Synthesis (Video)
In this video, you'll review how every protein molecule of an organism is synthesized.
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.
Methods of Producing Electricity
In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
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.
