Inside a Computer

👩‍🏫 Teacher’s Guide

Objective
Students will identify important parts inside a computer (motherboard, CPU, RAM, storage, power supply) and describe their basic jobs.

Teaching Notes

• Use a diagram or photo of an open desktop computer to point out parts.
• Explain that laptops and tablets also have these parts, but smaller and packed tightly.
• Keep explanations simple: each part has one main job.
• Emphasize safety: never open devices without adult help.

🧒 Student Worksheet

Concept and Helping Material

Inside a computer are many parts that work together. The CPU does the main thinking, RAM helps the computer work quickly, storage keeps files, and the motherboard connects parts like a big road map.

Computer Vocabulary and Definition

• — The main board that connects computer parts together.
• — The main part that does most of the computer’s thinking.
• — Short-term memory the computer uses while working.
• — Where the computer keeps files for a long time.
• — The part that gives electricity to the computer.

Computer Prtactices

• Label a computer diagram: motherboard, CPU, RAM, storage, power supply.
• Sorting game: Match each part to its job (CPU → thinking, storage → saving).
• Draw a simple ‘inside computer’ box and place labels in the right spots.
• Safety talk: Write 2 rules for handling devices safely.

Reflection

• Which inside part sounds the most important to you, and why?
• What is one safety rule about hardware?
