In this video learners view the valves and chambers of the heart.
By Barbara Liang
In this animated and interactive object, learners examine ABO blood antigens and Rh antigens and their compatibility.
Ascending Tract: The Posterior White Columns
In this animated activity, learners view the pathways and functions of the fasciculus gracilis and the fasciculus cuneatus.
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.
Reading a Triple Beam Balance
By Jill Crowder
Students identify the parts of a triple beam balance and practice measuring the mass of objects.
The Sense of Taste
In this interactive object, learners examine the structure and function of the sense of taste.
In this animated activity, learners examine the two major phases of cell division: mitosis and cytokinesis.
Measuring Volume Using a Graduated Cylinder
Learners view an explanation of how to read a graduated cylinder by measuring the lowest portion of the meniscus. A quiz completes the activity.
Newton's Second Law of Motion - Video
By Kim Ristow
In this learning activity you'll examine force, mass, and acceleration to understand this "Law of Acceleration."
Learners read a general description of the function and structure of leaves and examine drawings and microscopic views. A matching exercise completes the learning object.
The Anatomy of the Heart
By Wendy Dusek
In this animated and interactive object, learners identify the valves and chambers of the heart.
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 the Cell Membrane
By Becky Polk-Pohlman, Barbara Liang
In this learning activity you'll study the structure of the cell membrane and construct it using the correct molecules.
Identifying Eukaryotic Animal Cell Organelles
In this animated object, learners are introduced to the structure and function of animal cell organelles.
Muscle Cell Contraction
In this animated activity, learners examine muscle cell contraction and relaxation and consider the role of calcium ions.
The Sense of Hearing (Screencast)
In this screencast, learners examine hearing and balance. Detailed drawings of the outer, middle, and inner ear structures are included.
The Cell: Passive Transport Osmosis
In this animated object, learners examine water molecules moving through a semipermeable membrane.
In this animated and interactive object, learners examine ventilation, external and internal respiration, and gas transport.
Spelling of Bacteria Names
By Marise Hussey
Learners listen to the pronunciation of bacteria names and then type the words. They may choose the number of names that they wish to spell (up to 70). Immediate feedback is given, and a final score is provided at the end of the activity.
Biomolecules - The Lipids
In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.
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.
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.
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.
A Typical Animal Cell
By Gerald Heins
In this interactive object, learners identify the parts of an animal cell and its organelles.
In this learning activity you'll review how every protein molecule of an organism is synthesized by that organism in a prescribed process. This activity helps students understand the fundamental life process of making protein.
