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 a drag-and-drop exercise, the learner considers various food items and determines if they improve brain functioning. This learning object is designed for instructional assistants.

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.

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

Students read an explanation of the operation of an operational amplifier that functions as a comparator.

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.

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.

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

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.

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

Explore what proteins are, their structure, and their functions.

In this animated and interactive object, learners examine the structure and functions of granulocytes and agranulocytes. Two exercises complete the activity.

Learners will identify ladder logic diagrams and the logic functions they perform.

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

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

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

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.

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.

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