Learners read an explanation of the debits and credits of accounting as they relate to T accounts and the accounting equation. Illustrated examples are provided.

In this learning activity you'll describe the operation of a logic inverter using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

In this learning activity you'll explore the operation of a NAND gate using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

In this learning activity you'll review the operation of a NOR gate by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

The Effect of Temperature on the Vapor Pressure of a Liquid

Learners examine how vapor pressure is calculated. The vapor pressure of a liquid increases with increasing temperature. If the heat of vaporization and the vapor pressure at one temperature are known, the vapor pressure at a second temperature can be calculated.

In this learning activity you'll explore how an Exclusive-OR gate operates by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

The learner will understand the operation of the six fundamental logic gates and the inverter by using truth tables, Boolean Algebra equations, switch analogies, and written statements.

In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.
