Lesson summary
This lesson is part of a unit that explores how electricity and processed materials combine to power mobile phones. In this lesson, students will investigate the conductivity of various materials and apply this understanding to the circuitry inside a mobile phone. They will learn what makes a mobile phone work and where the materials in a mobile phone come from.
Learning intentions:
Students will...
- explore the properties of conductors and insulators by experimenting with different materials
- investigate the importance of these materials in the function and recycling of mobile phone components
- consider the environmental and economic impacts of the materials used in the production of mobile phones and their circuitry.
Success criteria:
Students can...
- construct a simple circuit and demonstrate how different materials can either conduct or insulate electricity
- describe the significance of using specific metals in mobile phone circuit boards and explain why these metals are considered precious
- evaluate the importance of recycling mobile phones by considering the environmental and economic impacts of the materials used in their production.
