The Cell: Passive Transport Osmosis (Video)
Explore what passive transport osmosis is and how it moves water through a semipermeable membrane.
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."
Anatomical Terminology: Relative Position Video
By Becky Polk-Pohlman
Students identify the various regions of the human body through video.
Mass Versus Weight
In this learning activity you'll explore the difference between mass and weight.
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.
By Barbara Liang
In this learning activity you'll review the structure and function of the different tissues of the human body.
Physiological Events at the Neural Synapse
In this learning activity you'll review information on the neural synapse.
The Food Pyramid
By Michele Williams
In this learning activity you'll explore the food pyramid and the recommended services.
The Sense of Smell
In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.
Anatomical Terminology: Body Regions
Students identify the various regions of the human body through drag-and-drop exercises.
Biomolecules - The Lipids
In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.
Biomolecules - The Proteins
In this animated object, learners read an introduction to protein structure and function.
The Solid State
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
In this well-illustrated object, learners examine the structures and properties of the four types of solids: molecular, metallic, ionic, and covalent network. Five interactive questions are provided.
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.
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.
The Stress Response
In this animated object, learners read a brief description of the roles of the hypothalamus, emotions, and adrenal secretions during the stress response.
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.
Anatomy of the Ear
By Donna Matusewic
The student identifies the anatomical parts of the ear and learns the purpose and function of these parts. A review follows the lesson.
By Jill Larson
In this interactive object, the learner practices identifying charges on ions.
In this animated activity, learners examine the two major phases of cell division: mitosis and cytokinesis.
The 12 Cranial Nerves
In this interactive and animated object, learners read a description of the number, name, and function of the cranial nerves. A matching quiz completes the activity.
The Four Types of Chemical Reactions
In this animated object, learners examine synthesis, decomposition, exchange, and reversible reactions.
The Cell Cycle
In this animated object, learners examine the different phases of a cell's life.
The Unipolar and Multipolar Neurons
Learners examine the location, structure, and function of the unipolar and multipolar neurons.
Transport Processes Requiring ATP
In this animated object, students observe how ATP energy is used to move substances across the cell membrane from an area of lower concentration to an area of higher concentration and when something too large needs to get in or out of a cell.
