The Structure of the Muscle Organ
By Barbara Liang
In this animated object, learners examine the various connective tissue layers of the muscle organ. The terms "prime mover," "synergist," "antagonist," "origin," and "insertion" are defined.
The Effect of Temperature on the Vapor Pressure of a Liquid
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine how vapor pressure is calculated. The vapor pressure of a liquid increases with increasing temperature. If the heat of vaporization and the vapor pressure at one temperature are known, the vapor pressure at a second temperature can be calculated.
In this animated and interactive object, learners examine the lifecycle of fungi including asexual and sexual reproduction. Learners test their knowledge by identifying a diagram and by completing a crossword puzzle.
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.
Muscle and Connective Tissue
In this colorful and interactive object, learners examine the structure and function of muscle and connective tissues. A quiz completes the activity.
The Appendicular Skeleton
In this animated object, learners examine the bones of the appendicular skeleton.
Biomolecules - The Proteins
In this animated object, learners read an introduction to protein structure and function.
The Cell: Passive Transport Osmosis
In this animated object, learners examine water molecules moving through a semipermeable membrane.
By Wendy Dusek
In this animated and interactive object, learners examine ventilation, external and internal respiration, and gas transport.
In this animated and interactive object, learners examine ABO blood antigens and Rh antigens and their compatibility.
Mass Versus Weight
By Kim Ristow
In this learning activity you'll explore the difference between mass and weight.
Skin and the Integumentary System
Learners examine the structure and function of skin including the production of melanin.
The Cell Cycle
In this animated object, learners examine the different phases of a cell's life.
Biomolecules The Carbohydrates
Learners read a brief introduction to monosaccharides, disaccharides, and polysaccharides. The processes for dehydration synthesis and hydrolysis are shown.
Heat Transfer: Conduction, Convection, Radiation
By Laurie Jarvis, Deb Simonson
In this animated activity, learners explore three major methods of heat transfer and practice identifying each.
Biomolecules: The Carbohydrates (Video)
By Becky Polk-Pohlman
Viewers watch an introduction to monosaccharides, disaccharides, and polysaccharides. The processes for dehydration synthesis and hydrolysis.
The Cell: Passive Transport Diffusion
In this animated object, learners view molecules as they collide and move between two different solutions. They also observe what happens when the temperature of the solutions is raised or lowered.
Construction of Free-Body Diagrams
In this learning activity you'll explore a step-by-step process to solve simple free-body diagrams. They identify forces acting in the x or y direction in interactive exercises.
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.
Identifying Eukaryotic Animal Cell Organelles
In this animated object, learners are introduced to the structure and function of animal cell organelles.
