ACTIVITY #1
Power Point Presentation (ICT Integration)
Game - like (the class is divided into 5 groups) presenting, the students will
identify the different parts of computer hardware.
The teacher shows the actual hardware components and encourages students in asking
question related to computer hardware.
Guide Questions:
a. How can you tell if some components of computer are defective?
b. What makes a computer just suddenly shut down?
DEVELOPMENTAL ACTIVITIES:
C. Preparatory (unlocking difficulties)
Activity #2 Group discussion and collaboration
The teacher group the students, based on a seat plan
The teacher will present a power point presentation.
Each group is provided with laboratory sheet to answer based on the task given.
PARTS FUNCTION
Hard Disk Is a high capacity, non-volatile, magnetic data storage device with a
volume (disk) that is usually non-removable
Motherboard It is the main circuit board of a microcomputer.
Power supply This enables different power supplies to be interchangeable
Heat Sink It transfers heat generated within a solid material to a fluid medium.
System Case Also known as a computer chassis.
RAM Is a volatile, meaning it holds data only when the power is on.
CPU The portion of a computer system that carries out the instructions.
DVD ROM Designed to optically access data stored on a DVD.
Video Card An expansion card which generates a feed of output images.
System Fan Any fan inside, or attached to, a computer case used for active cooling.
D. DISCUSSING NEW CONCEPTS AND PRACTICING NEW SKILLS #1
The teacher will show a video clip of a computer system servicing doing assemble and
disassemble computer hardware.
The teacher encourages students to ask related questions.

a. Give importance in wearing PPE in a workplace?
b. What are some unavoidable accidents may happen in a workplace?
Developing Mastery: Formative assessment
ACTIVITY #2: Cooperative Learning
The teacher groups the students into 5-7.
The teacher will present a station in performing pc assemble and disassemble
Every group will perform pc assembly and disassembly in the station provided.
Each group is provided with laboratory sheet and assigned task to filled up (inventory form).
The students should select appropriate tasks and test equipment suit to a certain job.
Performance will be assessing using rubrics.
RUBRICS
Components Percentage
Accuracy 50%
Adherence to the procedures 20%
Workmanship (applied safety precautions) 20%
Speed 10%
Performance Rating 100%
Remind students of the following:
Guidelines and instructions in performing unit assembly/disassembly are being provided in every
assigned stations
Leader will facilitate the activity task.
Every group are only given 10 minutes allotted time for disassembling computer hardware and another
10 minutes allotted time for assembly.
Procedure:
Steps on how to disassemble a computer
A. Personal Computer Disassembly
Unplugging all the cables and wires
Opening the outer shell / case
Removing the system fan
Removing the CPU Fan
Detaching the power supply
Removing the CD / DVD Drives
Detaching the Hard Drive
Pull Out the Motherboard
