Students examine the operation of synchronous and asynchronous inputs on a JK Flip-Flop.

In this interactive object, learners work 12 problems dealing with dc circuit analysis.

In this learning activity you'll explore various ways to calculate the power consumed in a series/parallel circuit.

In this animated object, learners examine the mechanisms for gas exchange among the lungs, blood, and tissues.

In this learning activity you'll review the structure and function of the different tissues of the human body.

In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.

Students review the best practices for using a ruler and answer five basic questions.

In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.

Learners study the types of symbols used on a P&ID diagram to indicate instruments. A quiz completes the activity.

The superposition theorem is explained as it relates to dc circuit analysis. Examples are given.

In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.

Students learn how to predict how circuits will respond to varying frequency. They solve for the magnitude and phase angles.

Learners follow a methodical approach for the dc analysis of series-parallel circuits.

Students study the concept that the voltage drop across a series circuit resistor is proportional to its resistance. They then complete a brief quiz.

In this animated object, learners examine the various connective tissue layers of the muscle organ. The terms "prime mover," "synergist," "antagonist," "origin," and "insertion" are defined.

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 learning activity you'll examine how a data file is broken into packets and transmitted over the Internet.

In this learning activity you'll examine a systematic method for converting a decimal number (base 10) into a binary number (base 2).

Learners examine a CBC and study the functions of blood cells, the normal range for each item on the CBC, and possible reasons for increases or decreases from the normal range.

In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.

In this learning activity you'll review information on the neural synapse.

In this animated object, learners examine the major descending tracts of the nervous system. A matching exercise completes the activity.

In this learning activity you'll explore Kirchhoff's Current Law and view examples of its application.

This learning object describes the production of an alternating current in a generator with a single-loop armature. An illustration of how a sine wave is produced is shown through animation.

Learners examine the internal parts of a DC electrical motor and then text their knowledge in a drag-and-drop exercise.
