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.
Body Sections and Divisions of the Abdominal Pelvic Cavity
In this animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.
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 review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
Identify your self-awareness score. In this learning activity, you'll answer 24 questions that attempt to measure three factors relating to self-awareness: introspection, public self-consciousness, and social anxiety.
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 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.
Learners assign oxidation numbers to atoms in neutral compounds and in polyatomic ions. Six examples are worked through in detail, and three problems are provided.
In this animated activity, learners examine the terms "half-reaction," "oxidizing agent," and "reducing agent" and follow five interactive examples to balance equations for oxidation-reduction reactions. Three problems are provided as a self-check.
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.
Learners examine pictorial drawings used in engineering including sectioned and exploded drawings. A sketching quiz is provided to help the learner create simple pictorial sketches by using orthographic views and an isometric template.
In this learning activity you'll apply information about three different sources of governmental power: Unitary, Confederate, and Federal to world governments.
