Quick summary: This lesson is part of a unit that explores how electricity and processed materials combine to power mobile phones. In this lesson, students use wires, batteries and light bulbs to learn what circuits are and how they work. Students will also learn how to read a circuit diagram, and use this information to find out how circuits and batteries power mobile phones.
- Students understand what a circuit is, how it works and how to draw a circuit diagram
- Students understand the basics of how electricity is used in a mobile phone circuit and battery
- Students understand that electricity travels around circuits in a current and that the circuit has to be complete for the current to flow
- Students understand how a battery stores electrical energy and how it works
- Students understand how circuits are used to power mobile phones
21st century skills:
Australian Curriculum Mapping
Year 5 & 6 – Design and Technology
- Investigate how electrical energy can control movement, sound or light in a designed product or system (ACTDEK020)
- Investigate characteristics and properties of a range of materials, systems, components, tools and equipment and evaluate the impact of their use (ACTDEK023)
Year 6 – Science (Chemical and Physical)
- Changes to materials can be reversible or irreversible (ACSSU095)
- Electrical energy can be transferred and transformed in electrical circuits and can be generated from a range of sources (ACSSU097)
General capabilities: Information and Communication Technology (ICT) Capability, Critical and Creative Thinking, Ethical Understanding.
Cross-curriculum priority: Sustainability.
Relevant parts of Year 5&6 achievement standards:
Year 5 & 6 – Design and Technology
Students critically examine technologies − materials, systems, components, tools and equipment − that are used regularly in the home and in local, national, regional or global communities, with consideration of society, ethics and social and environmental sustainability factors.
Year 6 – Science
They learn about transfer and transformations of electricity, and continue to develop an understanding of energy flows through systems.
Topic: Sustainability, Energy, STEM/STEAM.
Time required: 80 mins.
Level of teacher scaffolding: Medium – facilitate class discussion, support students in circuit building.
- Student Worksheets – one copy per student
- Device capable of presenting a video to the class
- The Parts Of A Phone sheet ready to project for the class
- Enough paper, pens and pencils for each group
- Minimum three lights (LED or similar), six alligator clip wires, one battery holder and a battery between each group of four students
- Enough deconstructed old mobile phones for groups of four students to have one each OR a class set of Parts Of A Phone
Note: LED lights have positive and negative charged points. Students will need support getting their ends right! If wires are attached incorrectly, the LED lights will break, so you will likely need several spares.
Note: If you choose to collect your own phones follow these instructions to deconstruct, How to Take Apart a Phone.
Note: Here are some examples of the electronic equipment in this lesson and where to buy them:
