The Food Pyramid
By Michele Williams
In this learning activity you'll explore the food pyramid and the recommended services.
Passive Transport: Filtration and Facilitated Diffusion
By Barbara Liang
In this animated object, learners examine processes that do not use ATP directly including hydrostatic pressure and facilitated diffusion with carrier proteins.
Regional Body Parts
By Gerald Heins
In this interactive object, learners identify a person's regional body parts.
The Axial Skeleton: The Skull and the Rib Cage
In this animated object, learners examine the eight cranial bones, the fourteen facial bones, and the ribs.
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.
What Is Electricity?
By Terry Bartelt
The learner studies how electrons travel from one atom to the next. Examples demonstrate how voltage is created by the use of a battery or through magnetism. A quiz completes the activity.
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.
By Wendy Dusek
In this highly animated and colorful object, learners examine the steps of carbohydrate digestion. A brief quiz completes the activity.
The Limiting Reagent in Chemical Reactions
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
In this interactive object, learners determine the limiting reagent and the excess reagent in chemical reactions. Learners test their knowledge by solving three problems.
Heat Transfer: Flash Version
By Deb Simonson
In this animated activity, learners explore three major methods of heat transfer and practice identifying each. This is the animated version with no audio.
By Debbie McClinton, Dr. Martin McClinton
Students read an explanation of chemical formulas in this animated activity. A quiz completes the object.
Newton's First Law of Motion
By Kim Ristow
The learner views several animations to study Newton's First Law of Motion, also known as "The Law of Inertia."
Newton's First Law of Motion - Video
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.
The Mole and Avogadro's Number
Learners examine how chemists use moles to "count" atoms by weight. Examples are given.
Glucose Metabolism for the Endocrine System
In this interactive object, learners read about the seven hormones that help regulate blood glucose. A quiz completes 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.
By Bruce Forciea
In this animated object, learners view the "T" and "P" waves and the "QRS complex." A brief quiz completes the activity.
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.
Protein Synthesis (Video)
By Becky Polk-Pohlman
In this video, you'll review how every protein molecule of an organism is synthesized.
Learners examine how melting, vaporization, and sublimation require energy input while freezing and condensation release energy.
Eukaryotic Cells: Assembling the Cell
By Kristine Snow
In this interactive object, learners read the definitions of the parts of a cell and assemble a basic eukaryotic cell in a drag and drop exercise. A matching quiz involving cell terms and their definitions completes the activity.
In this animated object, learners examine how thermal energy is transferred by conduction, convection, and radiation. A brief quiz completes the activity.
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.
Students solve a molarity problem in a drag and drop exercise.
