Power Sources Exploration

Overview

Duration: 60 minutes
Class Size: 8–12 students
Year Group: Year 7-8 (Ages 11-13)
Setting: MLD Special School
Subject: Science
National Curriculum Alignment:

• Key Stage 3 Science - Physics
• Investigate and understand energy sources and their uses
• Understand how energy is transferred and conserved
• Use simple models to explain scientific concepts

---

Learning Objectives

By the end of this lesson, students will be able to:

1. Understand that electrical appliances need a power source to work.
2. Identify and name common sources of power found in the home (e.g., batteries, mains electricity, solar power).

National Curriculum Reference:

• KS3 Science: Energy, electricity and circuits unit
• Pupils should be taught to recognise examples of energy transfer and explain how energy flows in simple systems.
• Pupils should recognise different sources of energy including renewable and non-renewable.

---

Success Criteria

• Students can say or show that an appliance requires a power source to function.
• Students can name at least three common power sources from their homes using objects or pictures.

Lesson Structure

1. Warm-up Activity (10 minutes)

Activity: “Power Detective”

• Purpose: Activate prior knowledge, engage curiosity.
• Procedure:
  • Teacher holds up common home electrical appliances one by one (e.g., a torch, a small radio, a blender).
  • Students guess and say how each works or what makes it ‘go’.
  • Teacher guides discussion: "Does it need power? Where does the power come from?”
• Materials: Real household appliances or clear large pictures/photos.

---

2. Introduction & Explanation (10 minutes)

Activity: “Meet the Power Sources!”

• Purpose: Introduce and name different power sources clearly.
• Procedure:
  • Teacher shows real objects or large pictures of common power sources:
    • Battery (show AA or AAA battery)
    • Mains electricity plug and socket (demonstration with socket cover for safety)
    • Solar panel model or picture
    • Hand-crank generator (if available) or picture
  • Teacher describes each using simple language and gestures—e.g.:
    • “Battery: small box that gives power.”
    • “Mains: power from the wall.”
    • “Solar: power from the sun.”
  • Students repeat names and key facts.
• Materials: Batteries, plug/socket model or safe demonstration, pictures or models of a solar panel and hand-crank generator.

3. Main Activity – Hands-on Exploration (25 minutes)

Part A: Power Match Game (15 minutes)

• Purpose: Active engagement through matching appliances to their power sources.
• Procedure:
  • Students are given cards/pictures of appliances and separate cards/pictures of power sources.
  • In small groups or pairs, students match each appliance to its correct power source.
  • Once matched, students discuss why this power makes the appliance work.
• Support: Teacher and assistants guide vocabulary and understanding, offer prompts as needed.
• Materials: Laminated picture cards of appliances (e.g., torch, TV remote, kettle) and power sources (battery, mains plug, solar panel).

Part B: Real Object Demonstration (10 minutes)

• Purpose: Connect theory to experience.
• Procedure:
  • Use a real torch with a battery inside—show how removing the battery stops it working.
  • Demonstrate a solar garden light outside or near window, show how sun gives it power (or use a torch to simulate).
  • Show a plug and socket, carefully explaining safety and how plugging in powers appliances.
• Safety: No open wiring. Use safe, supervised objects only.

4. Reflection and Assessment (10 minutes)

Activity: “Power Source Story”

• Purpose: Check understanding in a simple, personalised manner.
• Procedure:
  • Each student chooses one appliance from the lesson and tells the class (or a partner) what powers it and why.
  • Alternatively, students draw a picture of their favourite appliance and label its power source.
  • Teacher encourages use of learned vocabulary: battery, mains, solar.
• Assessment: Teacher listens for correct identification and simple explanation related to the success criteria.

---

Resources & Materials Needed

• Real appliances (torch, radio, kettle) or clear photos
• Batteries (AA, AAA)
• Plug and socket model or visual aid
• Laminated picture cards (appliances and power sources) for matching game
• Solar panel model or picture
• Whiteboard or flipchart with key vocabulary and visuals
• Drawing paper and crayons/coloured pencils

---

Differentiation & SEND Strategies

• Use simple, clear language and repeat key vocabulary often.
• Incorporate multisensory learning: see, touch, hear, and move.
• Visual supports: large pictures/cards, real objects to engage tactile and visual learners.
• Provide one-to-one or small group support when needed.
• Simplify tasks and use step-by-step instructions.
• Allow additional time for responses.
• Use praise and encouragement liberally to promote confidence.

---

Extension Ideas (For Higher Ability or Additional Time)

• Introduce basic idea of renewable vs non-renewable power sources through pictures (wind turbines, fossil fuels).
• Investigate what happens when appliances do not have power e.g., torch without battery won't light.
• Simple experiment: using a battery to light up an LED in a circuit kit.

---

Classroom Management Tips

• Set clear rules for handling real objects carefully and safely.
• Rotate small groups to keep engagement high.
• Make the learning fun by praising participation, using friendly competition in matching game.
• Use breaks and movement to maintain focus for MLD learners.

This carefully scaffolded, engaging approach ensures SEND students build concrete understanding of power sources relevant to their everyday lives aligned with the KS3 National Curriculum, empowering them to connect scientific concepts with real-world experience.
