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.
In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object. Front, side, and top orthographic views are shown.
In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.
Learners develop 3D visualization skills by examining front, side, and top orthographic views of objects. Using this information, students select the corresponding isometric view of each object.
Phase Relationships Between Line-Neutral and Line-Line Voltages
Learners view a demonstration showing that line-neutral voltages and line-line voltages are not in-phase with each other, but have a definite 30-degree relationship.
In this interactive object, learners view a mind map of the structural-functional Approaches and quiz themselves about the manifest and latent functions and the dysfunctions of social patterns.
This animated object illustrates the events leading to the migration of phagocytes into areas of tissue damage and/or bacterial presence. Learners view bacterial cell phagocytosis, its subsequent enzymatic digestion, and exocytosis.
In this animated learning object, students view the operation of an oscilloscope that is used to measure AC voltages. A brief quiz completes the activity.
In this interactive object, students view the various positions used during medical examinations. They then match the names of the positions with the correct images and with their descriptions.
In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.
In this interactive learning object, students view the ammeter connections for measuring currents in a parallel circuit with three branches on an energy concepts lab board. A brief quiz completes the activity.
In this animated activity, learners examine the construction of a binary counter using a JK flip-flop. The ability of the JK flip-flop to "toggle" Q is also viewed.
