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 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 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.
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.
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
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.
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 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.
