👋 0–10 min: Welcome & Re-engagement

• Greet students and settle them into the science space.
• Begin with a 2-minute "buzz starter" question:
  "What would your life be like without electricity for a day?"
  (Ask a few students to share; connect responses to the real-world reliance on circuits.)

---

🧠 10–25 min: WALT + Revision

Step-by-step

• Display WALT and Success Criteria on the board.
• Walk through each point, encouraging students to call out examples of what these may look like in practice.
• Use a short recap quiz on the whiteboard:
  • What is a 'load' in a circuit?
  • What role does a battery play?
  • Can a circuit work with a broken wire?

Use visuals and real parts to point during explanations.

---

👩‍🏫 25–45 min: Explicit Teaching

Teacher Models

• Under a visualiser, show the components: battery, wire, bulb, switch.
• Construct a simple circuit live, explaining each step. Highlight how connections must be complete.
• Show a broken circuit and ask students to identify the problem (missing connection, bulb blown, etc.).
• Introduce and draw basic circuit symbols on board — model translating a real circuit into a diagram.

Students jot the diagram into their journals, labelling components.

---

🔧 45–75 min: Guided Group Activity – Let's Build!

Activity: "Light Up the Path"

• Students form groups of 4.
• Using instruction booklets and their knowledge, build a working circuit to light a bulb.
• Encouraged to test different battery numbers, switch placements, and component positions.

Rotation Roles: In each group:

• Builder – Connects components.
• Reader – Reads the instruction steps.
• Recorder – Draws final circuit diagram & notes any issues.
• Tester – Ensures circuit works & checks connections.

Teacher role: Rotate and check in with groups. Use questioning:

• "Tell me what part this is."
• "What might happen if we reverse the battery?"
• "What do you think is causing this not to work?"

---

⚠️ 75–90 min: Testing and Troubleshooting

Teacher Challenge Circuit: Provide two preassembled broken circuits at a testing station.

• Invite groups to diagnose and fix them.
• Students write from their group what the issue was and how they fixed it, tying into Success Criteria.

---

🧠 90–105 min: Extension & Support Activities

🟢 Support for Struggling Students

• Provide simplified picture-based instructions.
• Offer a pre-connected circuit missing only one part (e.g. just attach battery).
• Work in a triad with Teacher Aide support.

Mini-goal: Can they get the bulb to light? Can they draw what worked?

🔵 Extension for Advanced Learners

• Challenge: Can you create a parallel circuit with 2 bulbs that still work if one is unscrewed?
• Introduce new components like a buzzer or fan.
• Measure brightness changes with 1 vs 2 batteries and record as a bar graph.

---

💬 105–115 min: Class Reflection & Journals

• Gather class together. Invite 3–4 groups to present:

  • What was your circuit design?
  • What went wrong—and how did you fix it?
  • What did YOU do in your group role?

• Students record in their Science Journals:

  • Draw final working circuit with labels
  • Self-reflect on one thing they learned and one concept they’re still unsure about

---

✅ 115–120 min: Pack-up & Exit Ticket

• Students return materials tidily to tubs.

• Complete a paper 'exit ticket' before leaving:

  ⭐ One thing I learned about circuits today _____
  ❓One question I still have is __________

Collect tickets to inform targeted revision in next lesson.

Differentiation Strategies

Low Ability Learners:

• Visual support (circuit building cards with images)
• Pairing with scaffolded peer in group roles
• Use sentence starters in journals: "My circuit used... It worked because..."

High Ability Learners (G&T):

• Design a new component challenge: “If you had a solar panel, how would you wire it into the circuit?”
• Introduce resistor components for exploration if available

---

🌟 Teacher Reflection Prompts (Post-Lesson)

• Which students confidently explained their circuits?
• Did anyone in particular demonstrate strong problem-solving under pressure?
• Was there enough challenge for advanced learners, and support for those needing it?
• How did hands-on engagement affect student enthusiasm?

---

This lesson embraces a hands-on, inquiry-based approach tailored to Year 6 learners’ development, underpinned by the Australian Curriculum and differentiated for diverse ability levels. Through role engagement, troubleshooting, and circuit building, students will not only see electricity in action but collaborate to bring it to life.

---

Next Lesson Preview: Lesson 5 – Investigating Conductors and Insulators
Students will test a variety of classroom materials to determine which allow electric current to flow, creating their own “Materials Lab Report”.
