Learning Intention

We are learning about hardware and software components of a computer.

---

Success Criteria

✅ I can identify key computer components such as the motherboard, CPU, RAM, hard drive, and power supply unit.
✅ I can explain the function of each component in a simple way.
✅ I can differentiate between hardware and software.

Lesson Duration

⏳ 35 minutes

Resources

• Video: Pre-selected educational video describing computer components (motherboard, CPU, RAM, hard drive, power supply unit).
• Physical computer components (if available): Old computers for students to explore hands-on.
• Printed component cards: Cards with names and descriptions of each part.
• Mini whiteboards & markers.

Lesson Breakdown

1. Introduction & Hook (5 mins)

👩‍🏫 Teacher-led Discussion:

• Pose the question: "What makes a computer work?"
• Record student responses on the board.
• Use an analogy: "A computer is like a human body – it has a ‘brain’ (CPU), ‘memory’ (RAM), a ‘power' source, and ‘storage’ like a backpack (hard drive).”
• Briefly introduce the terms hardware and software – explain that today, we will focus on hardware.

2. Video Viewing (8 mins)

📺 Students Watch an Engaging Video:

• The video should briefly explain the motherboard, CPU, RAM, hard drive, and power supply unit.
• Encourage students to jot down interesting facts or important terms they hear.
• Pause briefly after each component for a quick verbal recap.

3. Interactive Activity – Component Sorting (12 mins)

🚀 Hands-on Sorting Challenge:

• Divide students into small groups of 4.
• Give each group printed component cards – they must match the names of components to descriptions and images.
• If available, let students examine actual computer components (e.g. an old desktop tower with removed parts).

💡 Bonus Challenge:

• Each group picks one component and comes up with a fun way to explain it to the class in one sentence or action. For example:
  • "RAM is like a whiteboard – you can write on it, but when you turn it off, everything disappears!"

4. Wrap-Up & Reflection (8 mins)

🧠 Think-Pair-Share:

• Pose the question: "Which component do you think is the most important and why?"
• Students discuss in pairs, then some share answers with the class.

🎯 Exit Ticket – 3, 2, 1 Reflection:

• On mini whiteboards, students write:
  3️⃣ three things they learned
  2️⃣ two components they can name confidently
  1️⃣ one question they still have

🔄 Teacher Recap: Review common student questions to clarify misconceptions before the lesson ends.

Differentiation

🔹 For Support:

• Provide sentence starters for explanations.
• Use visual aids and real-life analogies for each component.

🔹 For Extension:

• Introduce students to software vs. hardware in more depth.
• Challenge them to research how storage sizes affect performance.

---

Assessment Opportunities

• Formative: Observe group discussions and sorting activity responses.
• Exit Ticket: Assess students’ understanding through their written reflections.

---

Teacher Reflection

📝 Next Steps:

• Based on student responses, determine if a follow-up lesson on software components is needed.
• Consider incorporating a hands-on activity like building a model computer in future lessons.
