How are mobile phones made?
#Did you know: There are more mobile phones in the world than there are people. So everyone has a responsibility to make sure they recycle their old mobiles phones and don't let them go to waste.
In this module students will appreciate and understand the variety and quantity of resources that come together to manufacture a mobile phone. Students will be introduced to the idea that products have life cycles and will be encouraged to consider the impact of the product life cycle on the environment.

- Scientific knowledge is used to inform personal and community decisions (ACSHE220)
- Read the Fact Sheet: Mobile Phone Manufacturing and watch the Mobile Phone Prezi (see links below) videos. Discuss the different stages of the mobile phone life cycle.
- Divide the students into five groups and assign each group with one stage of the product life cycle.
- Ask each group to produce a presentation of their stage of the product life cycle.
- As part of the presentation they need to investigate the social, environmental and economic benefits and costs at each stage of the product life cycle.
- The work can be presented as an oral activity, flow diagram, poster, Prezi or Powerpoint presentation.
- When all groups have produced their presentation, they can present it to the class as ‘experts’ on that stage of the mobile phone life cycle.
- Share your student work and upload the presentations to the MusterKids Zone on the MobileMuster website.
- Recap: using the information presented students can complete the Worksheet: How Are Mobile Phones Made? Either individually or as a class.
- Interactive whiteboard (IWB)
- Facts Sheet: Mobile Phone Manufacturing
- Prezi Video: Mobile Phone Manufacturing (Part 1, Part 2, Part 3, Part 4)
#Did You Know: To make mobile phones, manufacturers first need to extract raw materials from the earth.
They are then used to make each component of the mobile phone like the printed circuit board. This is the ‘brain’ of the phone, like a computer. They consist of many wires or circuits made of metal, located on a plastic or fibreglass board.
- Crude oil is extracted from the earth to make plastics, silicon and other materials to that are used to make the circuit boards.
- Metals such as copper, gold, lead, nickel, zinc, beryllium, tantalum and other metals are mined from the earth to make components that are used to make the board.
- Many of the raw materials that are used in the manufacturing of the circuit board contain substances that can be potentially harmful to the environment if they are buried in landfill.
There are many household appliances that use environmental rating systems to measure the sustainability of products. Vodafone has developed a voluntary environmental rating scheme which looks at the environmental and ethical performance of many of the mobile phones they sell.
Visit the Vodafone Eco Rating site, view the Video: Vodafone Eco Rating and look at how you can calculate the mobile phone’s impact on the environment. The rating system measures water usage, energy and raw materials, pollution, hazardous materials, carbon emissions, recyclability and ethical practices.
If you were an engineer working for a mobile phone manufacturer and wanted to create a new environmentally sustainable mobile phone, how would you design the phone? In your response consider the entire life cycle of a product — from materials acquisition, materials processing, manufacturing, packaging, transportation, use and disposal of the product.
