In this animated object, students examine the role that the solubility of water plays in various biological functions.

In this animated activity, learners view the input and output leads of a JK flip-flop. They also see how it functions in each mode of operation. A brief quiz completes the learning object.

In this interactive object, learners examine a mind map depicting manifest and latent functions of education. Quiz questions complete the activity.

In this animated activity, learners view the pathways and functions of the fasciculus gracilis and the fasciculus cuneatus.

Are you a member of a fragmented, conflicted, or smooth- functioning team? Learn the characteristics of each to build a stronger team.

Learners examine the functions of the three types of memory used by an Allen-Bradley SLC-500 programmable logic controller: the Executive ROM, Scratch Pad, and Processor File.

The target audience of this learning object is trigonometry students who have already learned what a radian is and have already derived the key values of the coordinates associated with common radian units, but now need to practice finding those values on the unit circle. The student does not need to know the definition of the six trig functions to do this activity.

In this learning activity you'll discover the functional differences between value and reference types within the .Net framework.

Learners examine the components of the x-ray tubehead, a sealed, heavy metal housing that contains the x-ray tube that produces dental x-rays. This object is designed to help students understand the functions and safety features of the tubehead.

Learners read how to create a spreadsheet to determine the voltage drop across a resistor in an AC circuit. The complex functions explained in other learning objects are used in this example.

Learners examine a 555 integrated circuit, which functions as a one-shot monostable multivibrator, and then test their knowledge. Immediate feedback is provided. Animations are used to show the sequential operations.

Students review the functions of the keys on the Starrett HB400 Optical Comparator controller.

In this learning activity you'll assemble the components of a prokaryotic cell and match the names and functions with each structure.

In this animated activity, learners examine how various NAND gate configurations and the logic signals produced throughout the circuit perform the functions of all of the other types of logic gates.

Students view schematics and truth tables that demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NAND gates.

Learners view the three zones of platelet structure, peripheral, structural, and organelle, and read about their functions.

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.

Learners read how the NOR gate can be configured to obtain the other common logic gates. Schematics and Boolean expressions demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NOR gates

In this colorful and animated activity, learners examine the four functions provided by a hydraulic reservoir. A brief quiz completes the learning object.

In this learning activity you'll relate statistics on aging in America to the functions and dysfunctions created by these demographic changes.
