Lesson Plan: OR Gates Physics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to determine the input and output of OR gates in logic circuits and complete truth tables for OR gates.

Objectives

Students will be able to

• recognize the symbol for an OR gate,
• recall the output of a single OR gate,
• evaluate the output of two or more OR gates connected together,
• use truth tables to evaluate the output of two or more OR gates connected together.

Prerequisites

Students should already be familiar with

• the idea that a binary signal has two possible values: 0 and 1,
• the idea that a logic gate is a device that takes one or more binary inputs and has one binary output,
• the idea that logic gates can be drawn as part of logic circuits, in much the same way that analog circuit components can be drawn as part of analog circuits.

Exclusions

Students will not cover

• any other types of logic gate (e.g., AND gates, NOT gates, NAND gates, NOR gates, XOR gates, etc.),
• algebraic representations of Boolean logic,
• the material or structural design of logic gates,
• combinations of more than one type of logic gate.
