Overview

Unit Title: Energizing Circuits Exploration
Lesson Number: 6 of 7
Lesson Duration: 120 minutes
Year Level: Year 6
Class Size: 26 students
School: Cannington Community College
Curriculum Alignment:
Australian Curriculum – Science (Year 6):
Science Understanding – Physical sciences

• ACSSU097 – Electrical energy can be transferred and transformed in electrical circuits and can be generated from a range of sources.

Science Inquiry Skills:

• ACSIS103 – Identify, plan and apply the elements of scientific investigations to answer questions and solve problems using equipment and materials safely and identifying variables.
• ACSIS104 – Decide variables to be changed and measured in fair tests, and observe, measure and record data with accuracy.

Cross-Curriculum Priority: Sustainability
General Capabilities: Critical and Creative Thinking, Ethical Understanding, Literacy, Numeracy, Personal and Social Capability

---

WALT (We Are Learning To):

• Construct and compare series and parallel circuits
• Identify and describe the advantages and disadvantages of series and parallel circuits
• Record and interpret scientific observations from electrical investigations

---

Success Criteria:

By the end of the lesson, students will be able to:
✔ Construct a simple series circuit and a parallel circuit using appropriate materials
✔ Verbally and visually explain the difference between the two types of circuits
✔ Evaluate which circuit is more appropriate for specific uses based on their functionality
✔ Work collaboratively and safely during investigations

---

Required Materials

For each group (groups of 4-5 students):

• 2 D-cell batteries
• 1 battery holder
• 3 light globes with holders
• Insulated copper wire with alligator clips
• Switches (2 per group)
• Circuit diagram templates (printed)
• Printed lab sheets (1 per student)
• Safety glasses
• Coloured pencils/markers
• iPads or Chromebooks for optional digital reflection (1 per group if available)

Lesson Breakdown

Session 1: Introduction & Exploration (30 minutes)

Warm-Up (10 mins)

• Begin with a brain buzz - Show students two simple circuits (one series, one parallel) on the IWB (Interactive Whiteboard). Ask:
  • "What differences do you notice?"
  • “What do you predict will happen if one light globe is removed from each?”

Mini-lesson and Demonstration (15 mins)

• Introduce key terms: series, parallel, current, voltage, open circuit, closed circuit
• Demonstrate both circuits practically with a working example on the front desk using a document camera:
  • Series circuit with 3 globes
  • Parallel circuit with 3 globes
• Use student input to co-construct a definition for series circuit and parallel circuit on an anchor chart for classroom display

Guided Discussion (5 mins)

• Open floor to student questions and predictions
• Prompt discussion on real-world applications e.g., fairy lights (series), home lighting (parallel)

Session 2: Investigations (60 minutes)

Group Circuit Construction (45 mins)

• Students work in mixed-ability groups of 4-5
• Each group receives a circuit challenge board (including steps and diagrams on constructing both types)
  • Task 1: Build a series circuit with 2 lightbulbs and a switch
  • Task 2: Build a parallel circuit with 2 lightbulbs and a switch
  • Task 3: Observe and record brightness, behaviour when a light is removed, and energy distribution
• Safety protocol discussed and implemented (gloves/glasses for careful handling)

Scientific Observation Sheet (Completed Individually):

• Diagram labelling
• Prediction and observation comparison
• Which circuit is more efficient? Why?

Teacher Focus during Activity:
Support struggling students with 1:1 or small group circuit checking. Ensure all groups test both circuits.

Support Activity (for students requiring additional help):

• Provide illustrated instructions with step-by-step diagrams
• One-on-one support available for construction and wiring circuits
• Use pre-wired example kits for hands-on scaffolded learning

Extension Activity (for advanced learners):

• Modify circuits using 3 or more globes and additional batteries
• Include a buzzer or motor to extend application
• Challenge: Can you create a hybrid circuit (combination of series and parallel)? Use your knowledge and explain its advantages in your science journal.

Session 3: Reflection & Consolidation (30 minutes)

Whole-Class Discussion (10 mins)

• Groups present findings and show working circuits
• Compare and contrast as a class: which is more reliable? Which is more energy efficient?

Interactive Sorting Activity (10 mins)

• On the whiteboard, slide images or descriptions of different devices
  • Students classify them as using series or parallel circuits (e.g., torch, Christmas lights, home lighting)

Exit Ticket (10 mins)

• Each student completes a quick “Snap Summary”:
  • “The best thing about parallel circuits is…”
  • “A real-world example of a series circuit is…”
  • “One troubleshooting tip for circuits is…”

Optional: Digital exit ticket using Padlet or Microsoft Forms

---

Assessment Opportunities

✔ Observation of participation and teamwork during circuit building
✔ Quality and accuracy of scientific observation sheet and drawings
✔ Responses during whole-class discussion and exit ticket
✔ Reflection journal entries (optional homework)

---

Differentiation

• Visual learners benefit from diagrams, colour-coding and step-by-step visuals
• Kinaesthetic learners engage in hands-on circuit construction
• Verbal learners participate in group discussion and oral presentation
• Struggling literacy learners offered sentence starters and scribed support if needed

---

Teacher Notes

• Circuits can be finicky; pre-test materials before lesson
• Record student quotes and experiences during the session for use in portfolios or reflective journal
• Reinforce safety procedures (no touching wires while circuit is connected, proper handling of batteries)
• Encourage cooperative learning by assigning rotating group roles: Engineer, Recorder, Tester, Timekeeper

---

Links to Future Learning

Prepares students for Lesson 7: Electrifying Innovations, where they will apply their circuit knowledge to design and present an energy-efficient device or electrical system.

---

Reflection Prompt for Teacher

After the lesson, reflect on:

• Which students excelled in the hands-on activities and why?
• How well did students understand the difference between circuit types?
• What would I do differently next time with the same objectives?
