1. Condensed Lesson Plan*
Content
Objectives (The Students Will Be Able To:)
Methods
Evaluation
Parts of the computer
Identify key parts of a computer
Direct – PowerPoint presentation with handout for students
Monitor student response to questioning. Quiz at end of week.
Functions of the computer
Categorize parts of a computer by function (input, output, processing, & storage) and explain how parts work together
Direct – PowerPoint presentation with discussion and questioning included
Direct – watch video
Quiz
Parts / Functions
Compare between human and computer parts & functions
Indirect – Comparison activity to make predictions and draw analogy between humans and PC’s
Indirect – have students review web article from “Howstuffworks” web site
Class will be divided into 4 groups and given a part of the PC and asked to come up with a human comparison and share with the whole class. Monitor students group discussion and use worksheet to ensure correct comparisons are made.
* Materials, Accommodations, applicable Standards accounted for but not included in this condensed format

2. Four Functions of a Computer
Input
Process
Storage
Output
In 4 assigned groups spend five minutes discussing what you think human function relates to your assigned function and computer examples

3. Motherboard Contains: CPU Ports
Memory chips that control functions like video & networking
Connects to main power source

4. Input
Gets information into the computer and translates to digital form. Comes from devices such as:
Keyboard (Qwerty style from typewriters)
Mouse
Scanner
Microphone
Camera
Graphic tablet
Texts, graphics, sounds, video, music, are all transformed into binary code. Letters, words, numbers, and even colors all use the universal ASCII language
ASCII – zeros and ones stand for electrical pulses (1 = +, 0 = neutral
Each zero or one is a bit and 8 bits = a byte
A byte is a single letter, number, symbol, or sound
Human comparison – Ears, Eyes, Nose, Mouth

5. Input Devices

6. Process CPU is main processing unit of a computer
It coordinates all of the actions of the machine by following instructions such as:
Perform calculations
Interact with other components to operate the computer
The microprocessor is the primary work area where information gets processed
Software (i.e. games or programs on the computer) are the sets of instructions that you give to the processor
Microprocessor primary steps are:
Fetch
Decode
Execute
Human Comparison – Certain Sections of the Brain or Digestive System

7. Storage Computers have two types of storage Temporary Long-term
RAM or Random Access Memory stores information as you use it
Constantly gets erased and rewritten as you open & close files
Long-term
Hard Drives
CD-ROMs
Floppy disks
Flash Drives
The capacity of these types of memory vary – but the more you have, generally the better
Human Comparison – Brain (Different parts – long-term and short –term memory)

8. Process and Storage

9. All of these can store the same amount of information

10. Output
Display the information the computer has been processing or retrieve the information or result of the instructions given earlier
Monitor
Printer
Speakers
Human Comparison – Written work, speech, song, poem, painting, sculpture, repaired car
