A single page PDF handout about modern glass with information about how it is produced and coloured.
Old cloths and plastic bags can be made into something really desirable and processing plastic is really a relatively simple exercise in applying heat and pressure.
Glass is an extremely durable material, though fragile, and can be recycled many times. Recycling glass requires far less energy than manufacturing it from raw materials, saving both cost and environmental damage. The PowerPoint file presents information about recycling glass, including a video linked from YouTube, and challenges students to sort glass from mixed waste as would be required for recycling.
This activity is designed to be completed in class over a period of a week or a little more. It requires students to collect, weigh, record, and analyse the waste they produce during the week. It will help them to realise how much waste is generated and to recognise the differences between general waste, recycled products, and reusable materials. There are questions to help with their thinking about the issues.
This presentation addresses how braiding fibres can increase strength with a video demonstration of a braider that can handle up to 144 strands. There are questions for students to answer.
Separating materials in a materials recovery facility requires a lot of work. Can you imagine how hard robots or machines have to work to do that job with tonnes and tonnes of waste material? This experiment will give you some idea.
This presentation is designed to engage students in investigating the nature and some history of glass from ancient times to current types and applications.
This unit of work is designed for use over an extended period of 11 or more lessons. It aims to build skills and understanding around green terms such as sustainability, recyclability, and biodegradability in real world contexts, exploring perspectives of decision-makers perspectives, such as company directors, and considerations around using sustainable methods.
