Methods of Producing Electricity
By Terry Bartelt
In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
By Jill Larson
In this animated and interactive object, learners follow two rules to write unit conversion fractions.
Golder Finches Get the Girls
By Andrea Huntoon
Explore how a goldfinch interacts with its environment and how it's affected by environmental changes.
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.
Atomic Symbols, Atomic Numbers, and Mass Numbers
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners read definitions of atomic symbols, atomic numbers, and mass numbers and then answer questions about the number of neutrons, protons, and electrons in select elements.
Anatomical Terminology: Relative Position
By Barbara Liang
In this interactive learning activity, learners review the terms used to describe relative position of body parts in order to have a common set of words to describe their position.
How Pressure Changes Boiling Temperature
By Terry Bartelt, Terry Fleischman
Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.
Identifying Eukaryotic Animal Cell Organelles
In this animated object, learners are introduced to the structure and function of animal cell organelles.
In this animated object, learners examine how thermal energy is transferred by conduction, convection, and radiation. A brief quiz completes the activity.
Learners examine the meaning of oxidation, reduction, and half-reaction, and watch a film showing the deposition of copper metal from the reduction of copper (II) ion by aluminum. A brief quiz completes the activity.
In this animated object, the learner examines 17 types of joint movement.
Skin and the Integumentary System
Learners examine the structure and function of skin including the production of melanin.
Measuring Volume Using a Graduated Cylinder
By Jill Crowder
Learners view an explanation of how to read a graduated cylinder by measuring the lowest portion of the meniscus. A 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.
Classification of Joints
In this animated object, learners examine the different types of joints and their movements.
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."
The Appendicular Skeleton
In this animated object, learners examine the bones of the appendicular skeleton.
The Cell: Passive Transport Diffusion (Video)
Explore what passive transport diffusion is and how it moves water through a membrane.
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.
The Cell: Passive Transport Osmosis
In this animated object, learners examine water molecules moving through a semipermeable membrane.
Heat Transfer: Flash Version
By Deb Simonson
In this animated activity, learners explore three major methods of heat transfer and practice identifying each. This is the animated version with no audio.
A Typical Animal Cell (Video)
By Becky Polk-Pohlman
In this video, learners view the parts of an animal cell and its organelles.
The Anatomy of the Heart (Video)
In this video learners view the valves and chambers of the heart.
The Anatomy of the Heart
By Wendy Dusek
In this animated and interactive object, learners identify the valves and chambers of the heart.
