In this animated object, learners examine the different types of joints and their movements.

In this animated activity, learners examine muscle cell contraction and relaxation and consider the role of calcium ions.

Learners read how the transfer function for a RC high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

In this animated object, learners examine synthesis, decomposition, exchange, and reversible reactions.

In this learning activity you'll observe the growth of gram negative organisms and determine if they're lactose positive or negative.

In this animated object, learners examine the structure and function of intracellular and extracellular fluid. They also read about the most common electrolytes in the body and complete a matching exercise to test their knowledge.

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.

Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.

Learners review guidelines for the proper use of a dial caliper. Illustrations appear throughout the learning object.

In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

In this interactive object, learners examine the structure and function of the sense of taste.

In this animated object, learners examine processes that do not use ATP directly including hydrostatic pressure and facilitated diffusion with carrier proteins.

Students review the Voltage Divider Rule and work practice problems.

In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

In this learning activity you'll practice using the 4-input truth table.

Learners examine the differences and similarities between hydraulic and pneumatic systems.

In this animated object, learners compare the mode of action of steroids with the action of amino acid-based hormones.

In this interactive object, learners review case studies and identify complex arterial blood gases.

In this animated and interactive object, learners identify musculoskeletal fractures.

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.

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 read an overview of records management and then classify records as "vital," "important," "useful," or "nonessential" in a drag-and-drop exercise.

Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.

Learners consider the Apgar scores for several fictitious newborns. They are then given an Apgar score and proceed to create a situation in which a newborn would receive that rating.
