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.
The Anatomy of the Heart
By Wendy Dusek
In this animated and interactive object, learners identify the valves and chambers of the heart.
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.
Cell Division
By Barbara Liang
In this animated activity, learners examine the two major phases of cell division: mitosis and cytokinesis.
Respiratory Basics
In this animated and interactive object, learners examine ventilation, external and internal respiration, and gas transport.
Lewis Dot Structures of Covalent Compounds
By Dr. Miriam Douglass, Dr. Martin McClinton
In this interactive and animated object, students distribute the valence electrons in simple covalent molecules with one central atom. Six rules are followed to show the bonding and nonbonding electrons in Lewis dot structures. The process is well illustrated with eight worked examples and two interactive practice problems.
Identifying Eukaryotic Animal Cell Organelles
In this animated object, learners are introduced to the structure and function of animal cell organelles.
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.
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.
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."
How to Read a Caliper
By Barbara Anderegg
In this interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.
Intermolecular Forces
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
In this well-illustrated activity, learners examine the three types of intermolecular forces: dipole-dipole forces, London or Van der Waals forces, and the hydrogen bond. Two interactive questions are included.
