Detaching and Attaching Computer Components Safely

Ron Herron

Description

Using safe practices, students detach and attach the components of a computer system. When the task is completed, the computers should work properly as before.

Materials

-8 computers for 16 students,
one for each group of two students)
-8 tool kits
-8 writing pads
-8 pencils or pens
-Class copies of questions in attached file

Preparations

1. Purchase note pads and pencils.
2. Gather all required tools.
3. Gather computers that will be required.
4. Telescopic magnet pointer for pointing to components for identification and retrieving screws that are dropped down in the computer may be used. (Optional)

Procedures

NOTE: Prior to this lesson, students have already received instruction on all of the different computer components and how they work.

DAY 1
Teacher leads students in step-by-step procedures of detaching/attaching computer components.

1. Divide class into groups of two students.

2. Allot one computer for each group.

3. Hand out note pads and pencils so that students can write down the step-by-step procedures.

4. Present safety practices to the class to include:
a. Shutting down computer.
b. Unplugging the computer.
c. Grounding themselves by touching the metal computer case to dissipate static electricity.
d. Inventory tools after attachment of components to make sure no tool is left in the computer before powering up.

5. Issue the required tools to each group.

SPECIAL NOTE: At this point, the students observe, record, and then perform the procedures demonstrated by teacher in Steps 6-18 below.

6. Demonstrate safety practices.

7. Remove computer case cover by removing screws on the back of the computer.

8. Detach all expansion cards (video card, sound card, network interface card, etc.) by removing the screws that attach the expansion cards to the motherboard.

9. Unplug data cables from the hard drive, floppy drive, and CD-ROM and unplug data cables from motherboard.

10. Unplug power supply cable from hard drive, floppy drive, and CD-ROM.

11. Detach the hard drive, floppy drive, and CD ROM by removing attachment screws.

12. Detach memory from motherboard.

13. Detach CPU (Central Processing Unit) fan and heat sink from CPU.

14. Detach CPU from motherboard.

15. Unplug power supply from motherboard.

16. Detach power supply by removing screws on back of the computer case.

17. Remove color-coded wires for the power button, speaker, power light, hard drive light, reset button, and sleep mode. Be sure to remind students to write down where the color-coded wires attach to the motherboard on their note pads.

18. Detach motherboard from the computer case by removing the attachment screws.

DAY 2
1. Review the procedures from DAY 1. Acknowledge any questions from the students by giving formative feedback in the form of affirmative and corrective statements.

2. Lead step-by-step procedures for setting up the computer. Repeat steps 1-18 in reverse order to attach the components to the computer. At the completion of this task have students inventory tool kits to make sure no tool is left in computer before powering up.

DAY 3
1. Review the procedures from DAY 2. Acknowledge any questions from the students regarding DAY 1's or DAY 2ís lessons by giving formative feedback in the form of affirmative and corrective statements.

2. Students perform step-by-step procedures on their own.

3. Teachers point to components asking students for identification. Incorporate questions as the students are detaching and attaching the components. (See Associated File for sample questions.)

Assessments

Evidence: Students detach and attach the components of the computer while using safe practices.

Criteria: Performance Task (Observation)
1. Observe students while using safe practices in this distinct order:
a. Shutting down computer.
b. Unplugging the computer.
c. Grounding themselves by touching the metal case of the computer to dissipate static electricity.

2. Observe students while detaching the components (hard drive, floppy drive, CD-ROM, CPU, memory, expansion cards, power supply, and motherboard) from the computer.

3. Observe students while students then reattach the components to the computer.

4. Point to components for students to verify identification and ask questions about components as the components are being detached and attached.

Note: Formatively assess students as they use the technology tools. Provide assistance for students who are experiencing difficulty and monitor accordingly.

Extensions

Pairing an ESE student with a student that has a firm understanding of the lesson is a successful strategy.
