Physiological Events at the Neural Synapse
By Barbara Liang
In this learning activity you'll review information on the neural synapse.
Construction of the Cell Membrane (Video)
By Becky Polk-Pohlman
In this video you'll study the structure of the cell membrane and construct it using the correct molecules.
The Vascular System of the Kidneys
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.
Mole Ratios in Chemical Equations
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
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.
Mass Versus Weight
By Kim Ristow
In this learning activity you'll explore the difference between mass and weight.
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.
By Jill Larson
In this animated object, students examine what happens when electrons share molecules.
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 Sense of Smell
In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.
By Carol Parent-Paulson
This animated object illustrates the events leading to the migration of phagocytes into areas of tissue damage and/or bacterial presence. Learners view bacterial cell phagocytosis, its subsequent enzymatic digestion, and exocytosis.
The Brain - Anatomy and Function
By Susan Heitman
Learners review and reinforce their knowledge of brain anatomy and function in this learning activity.
Acids & Bases
Students read different definitions of "acids" and "bases." In an interactive exercise, they identify if a substance is an acid or a base.
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.
Naming Compounds Containing Polyatomic Ions
Learners examine a table of common polyatomic ions. Eight examples are provided for practice.
The Autonomic Nervous System - Sympathetic Division
Learners examine the function and wiring of the sympathetic nervous system.
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.
Chytrids, as members of this group are known, are found everywhere. In this animated learning object, students examine the role of chytrids and their impact on the environment.
Red Blood Cells
In this animated and interactive object, learners examine the red blood cell's life cycle and function. A brief exercise completes the activity.
Vapor pressure is the pressure exerted by molecules in the gas phase in equilibrium with a liquid or a solid. Two examples are used to illustrate vapor pressure: the drying of clothes and the evaporation of ice.
The Structure of an Atom
Students examine atomic structure and the octet rule.
By the end of this module, you'll be able to:
- Identify actions that can reduce biosecurity risk
- Develop a biosecurity action plan for a farm
- Select the most cost effective strategies
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.
Changes in Our World: Chemical and Physical (Screencast)
By Deb Simonson
In this screencast, learners examine the kinds of physical and chemical changes that occur in substances.
How the Brain Develops (Screencast)
By Mary Beth Boettcher
In this interactive learning object, learners study the parts of the brain and then test their knowledge in a drag-and-drop exercise.
By Dr. Miriam Douglass, Dr. Martin McClinton
In this interactive and animated object, learners use solubility rules to predict when an insoluble ionic compound will precipitate in a double replacement reaction. Step-by-step examples are given.
